SMP

Single matrix preconditioner (SMP) builds a preconditioner using user defined off-diagonal parts of the Jacobian.

Overview

The Single Matrix Preconditioner (SMP) builds one matrix for preconditioning. As an example, consider the system:

var element = document.getElementById("moose-equation-8b8267d0-297c-422f-ba6a-d8d2fbdcaf40");katex.render("\\begin{aligned} \\nabla \\cdot k(s,T) \\nabla T &= 0 \\\\ \\nabla \\cdot D(s,T) \\nabla s &= 0 , \\end{aligned},", element, {displayMode:true,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});

Users can then specify which off-diagonal blocks of the matrix to use like


off_diag_row    = 's'
off_diag_column = 'T'

Which would produce a preconditioning matrix like this:

var element = document.getElementById("moose-equation-eef52855-64a1-4ce1-8894-fe0d8951d85e");katex.render("\\boldsymbol{M} \\equiv \\begin{bmatrix} \\left(k(s,T) \\nabla \\phi_j, \\nabla \\psi_i\\right) & \\boldsymbol{0} \\\\[3pt] \\left(\\frac{\\partial D(s,T)}{\\partial T_j} \\nabla s, \\nabla \\psi_i\\right) & \\left(D(s,T) \\nabla \\phi_j, \\nabla\\psi_i\\right) \\end{bmatrix}", element, {displayMode:true,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});

In order for this to work, the computeQpOffDiagJacobian() function must be provided in the kernels that computes the required partial derivatives. To use all off diagonal blocks, you can use the following input file syntax:


full = true

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.
# Beam is along the z axis

# Test to verify the fundamental natural frequency of a one element ADComputeShellStress
# BCs: Clamped on one end, free on others.
# Initial perturbation applied to edge of the beam. After that, the shell vibrates freely.
#
# Results have been compared for various thicknesses with the following approximate Results
# (Moose results were obtained with 8 elements along the length)
# Thickness = 0.1. Reference freq: 10.785 Hz, Moose freq: 10.612 Hz
# Thickness = 0.05. Reference freq: 5.393 Hz, Moose freq: 5.335 Hz
# Thickness = 0.025. Reference freq: 2.696 Hz, Moose freq: 2.660 Hz
#
# Reference values have been obtained from Robert Blevins, "Formulas for Dynamics, Acoustics and Vibration",
# Table 5.3 case 11. Formula looks like: f = lambda^2/(2*pi*a^2) * sqrt(E*h^2/(12*(1-nu*nu))), where lambda
# changes as a function of shell dimensions.

# This test uses one single element for speed reasons.

# Here, the shell, instead of being on the XY plane, is oriented at a 45 deg. angle
# with respect to the Y axis.

# Represents a unique Maxwell module with E = 10GPa and eta = 10 days with an imposed eigenstrain alpha = 0.001.
# The behavior is set up so that the creep strain is driven by both the elastic stress and the internal
# stress induced by the eigenstrain (E * alpha).
#
# In this test, the specimen is free of external stress (sigma = 0) so the creep deformation only derives from
# the eigenstrain. The total strain to be expected is:
#     epsilon = alpha * (1 + t / eta)
# Both the stress and the elastic strain are 0.

# Hertz Contact: Sphere on sphere

# Spheres have the same radius, Young's modulus, and Poisson's ratio.

# Define E:
# 1/E = (1-nu1^2)/E1 + (1-nu2^2)/E2
#
# Effective radius R:
# 1/R = 1/R1 + 1/R2
#
# F is the applied compressive load.
#
# Area of contact a::
# a^3 = 3FR/4E
#
# Depth of indentation d:
# d = a^2/R
#
#
# Let R1 = R2 = 2.  Then R = 1.
#
# Let nu1 = nu2 = 0.25, E1 = E2 = 1.40625e7.  Then E = 7.5e6.
#
# Let F = 10000.  Then a = 0.1, d = 0.01.
#

## Note: There is not a good way to check the result.  The standard approach is
## to map contact pressure as a function of radius, but we don't have the
## contact pressure available.  See the description on Wikipedia for details of
## analytic equations, and the Abaqus Benchmarks Manual, 1.1.11, for a plot of
## contact pressure vs. radius.

# Define E:
# 1/E = (1-nu1^2)/E1 + (1-nu2^2)/E2
#
# Effective radius R:
# 1/R = 1/R1 + 1/R2
#
# F is the applied compressive load.
#
# Area of contact a::
# a^3 = 3FR/4E
#
# Depth of indentation d:
# d = a^2/R
#
#
# Let R1 = R2 = 2.  Then R = 1.
#
# Let nu1 = nu2 = 0.25, E1 = E2 = 1.40625e7.  Then E = 7.5e6.
#
# Let F = 10000.  Then a = 0.1, d = 0.01.

# Two phase density-driven convection of dissolved CO2 in brine
#
# Initially, the model has a gas phase at the top with a saturation of 0.29
# (which corresponds to an initial value of zi = 0.2).
# Diffusion of the dissolved CO2
# component from the saturated liquid to the unsaturated liquid below reduces the
# amount of CO2 in the gas phase. As the density of the CO2-saturated brine is greater
# than the unsaturated brine, a gravitational instability arises and density-driven

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam. The lumped
# mass also has a moment of inertia associated with it.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# Moment of inertia of lumped mass:
# Ixx = 0.2
# Iyy = 0.1
# Izz = 0.1
# mass proportional damping coefficient (eta) = 0.1

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The displacement time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y              vel_y               accel_y
# 0.0    0.0                 0.0                 0.0

# Simple reaction-diffusion example to illustrate the use of the SolidKineticReactions
# action.
# In this example, two primary species a and b diffuse towards each other from
# opposite ends of a porous medium, reacting when they meet to form a mineral
# precipitate. The kinetic reaction is specified in the SolidKineticReactions block as:
#
# kin_reactions = '(1.0)a+(1.0)b=mineral'
#
# where a and b are the primary species (reactants), mineral is the precipitate,
# and the values in the parentheses are the stoichiometric coefficients for each
# species in the kinetic reaction.
#
# The SolidKineticReactions action creates all the required kernels and auxkernels
# to compute the reaction given by the above kinetic reaction equation.
#
# Specifically, it adds to following:
# * An AuxVariable named 'mineral' (given in the RHS of the kinetic reaction)
# * A KineticDisPreConcAux AuxKernel for this AuxVariable with all parameters
# * A CoupledBEKinetic Kernel for each primary species with all parameters

# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is positive for a < 0.25, ie dissolution for a(t=0) < 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
#   = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity
#
# This test checks that (a + c / porosity) is time-independent, and that a follows the above solution
#
# Aside:
#    The exponential curve is not followed exactly because moose actually solves
#    (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#    which does not give an exponential exactly, except in the limit dt->0

# Buckley-Leverett 1-phase.
# The front starts at (around) x=5, and at t=50 it should
# have moved to x=9.6.  The version below has a nonzero
# suction function, and at t=50, the front sits between
# (about) x=9.6 and x=9.9.  Changing the van-Genuchten
# al parameter to 1E-4 softens the front so it sits between
# (about) x=9.7 and x=10.4, and the simulation runs much faster.
# With al=1E-2 and nx=600, the front sits between x=9.6 and x=9.8,
# but takes about 100 times longer to run.

# Dissociation of H2O at 25C
# The dissociation of water into H+ and OH- is given by
# the equilibrium reaction H20 = H+ + OH-
#
# This can be entered in the ReactionNetwork block using
# Aqueous equilibrium reaction: - H+ = OH-, Keq = 10^(-13.9951)
#
# Note that H2O does not need to be explicitly included.
#
# The primary chemical species is H+, and the secondary equilibrium
# species is OH-.
#
# The initial concentration of H+ is 10^-7, which is its value in neutral
# water. The pH of this water is therefore 7.

# Test for small strain Euler beam bending in y direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poisson's ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 5.78e-2 m

# Using 10 elements to discretize the beam element, the FEM solution is 5.766e-2 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable.  Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/time.  Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz   (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz   (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/s/m^3.  The ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t
# The relationship between the constant poroelastic source
# s (m^3/second/m^3) and the PorousFlow source, S (kg/second/m^3) is

# Illustrates desorption works as planned.
#
# A mesh contains 3 elements in arranged in a line.
# The central element contains desorped fluid.
# This desorps to the nodes of that element.
#
# In the central element, of volume V, the following occurs.
# The initial porepressure=1, and concentration=1.
# The initial mass of fluid is
# V * (2 * porosity * density + (1 - porosity) * concentration)
# = V * 1.289547
# Notice the factor of "2" in the porespace contribution:
# it is because the porepressure is evaluated at nodes, so
# the nodes on the exterior of the centre_block have
# nodal-volume contributions from the elements not in centre_block.
#
# The mass-conservation equation reads
# 2 * porosity * density + (1 - porosity) * concentration = 1.289547
# and the desorption equation reads
# d( (1-porosity)C )/dt = - (1/tau)(C - dens_L * P / (P_L + P))
# where C = concentration, P = porepressure, P_L = Langmuir pressure
# dens_L = Langmuir density, tau = time constant.
# Using the mass-conservation equation in the desorption equation
# yields a nonlinear equation of P.  For dt=1, and the numerical values
# given below this yields
# P = 1.83697
# and
# C = 0.676616
# The desired result is achieved by MOOSE

    # Navier Stokes. The user can specify supg = true to apply streamline
    # upwind petrov-galerkin stabilization to the momentum equations. This
    # is most useful for high Reynolds numbers, e.g. when inertial effects
    # dominate over viscous effects. The user can also specify pspg = true
    # to apply pressure stabilized petrov-galerkin stabilization to the mass
    # equation. PSPG is a form of Galerkin Least Squares. This stabilization
    # allows equal order interpolations to be used for pressure and velocity.
    # Finally, the alpha parameter controls the amount of stabilization.
    # For PSPG, decreasing alpha leads to increased accuracy but may induce
    # spurious oscillations in the pressure field. Some numerical experiments
    # suggest that alpha between .1 and 1 may be optimal for accuracy and
    # robustness.

#
# Effective radius R:
# 1/R = 1/R1 + 1/R2
#
# F is the applied compressive load.

#This problem from [Wilson 1979] tests the thermal strain term in the
#interaction integral. In this variant of this test, rather than using the
#standard mechanism for applying thermal strain, the eigenstrain for the
#thermal strain is applied using a generic object, which also supplies its
#gradient. This gradient is used in the interaction integral, with a nearly
#identical result to that from the version of this test that applies that
#in the standard manner.
#
#theta_e = 10 degrees C; a = 252; E = 207000; nu = 0.3; alpha = 1.35e-5
#
#With uniform_refine = 3, KI converges to
#KI = 5.602461e+02 (interaction integral)
#KI = 5.655005e+02 (J-integral)
#
#Both are in good agreement with [Shih 1986]:
#average_value = 0.4857 = KI / (sigma_theta * sqrt(pi * a))
#sigma_theta = E * alpha * theta_e / (1 - nu)
# = 207000 * 1.35e-5 * 10 / (1 - 0.3) = 39.9214
#KI = average_value * sigma_theta * sqrt(pi * a) = 5.656e+02

# Test for damped small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# mass proportional rayleigh damping(eta) = 0.1
# stiffness proportional rayleigh damping(eta) = 0.1
# HHT time integration parameter (alpha) = -0.3
# Corresponding Newmark beta time integration parameters beta = 0.4225 and gamma = 0.8

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the behaves like a Euler-Bernoulli beam.

# The displacement time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time  disp_y                vel_y                accel_y

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

# This file uses a PorousFlowFullySaturated Action.  The equivalent non-Action input file is pp_generation_unconfined_constM.i
#
# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable.  Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source, s, has units m^3/second/m^3.  Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz   (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz   (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/second/m^3.  The ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t
# The relationship between the constant poroelastic source
# s (m^3/second/m^3) and the PorousFlow source, S (kg/second/m^3) is

(modules/porous_flow/examples/restart/gas_injection.i)

# Using the results from the equilibrium run to provide the initial condition for
# porepressure, we now inject a gas phase into the brine-saturated reservoir. In this
# example, where the mesh used is identical to the mesh used in gravityeq.i, we can use
# the basic restart capability by simply setting the initial condition for porepressure
# using the results from gravityeq.i.
#
# Even though the gravity equilibrium is established using a 2D mesh, in this example,
# we shift the mesh 0.1 m to the right and rotate it about the Y axis to make a 2D radial
# model.
#
# Methane injection takes place over the surface of the hole created by rotating the mesh,
# and hence the injection area is 2 pi r h. We can calculate this using an AreaPostprocessor,
# and then use this in a ParsedFunction to calculate the injection rate so that 10 kg/s of
# methane is injected.
#
# Results can be improved by uniformly refining the initial mesh.
#
# Note: as this example uses the results from a previous simulation, gravityeq.i MUST be
# run before running this input file.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 2D axisymmetric geometry.
# This test uses the strain calculators ComputeAxisymmetricRZSmallStrain
# and ComputeAxisymmetricRZIncrementalStrain which are generated by the
# SolidMechanics QuasiStatic Physics depending on the cli_args given in the tests file.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
#   where:
#          Pi = inner pressure
#          Po = outer pressure
#          ri = inner radius
#          ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.
# Beam is inclined on the YZ plane at 45 deg.

# Example of reactive transport model with precipitation and dissolution.
# Calcium (ca2) and bicarbonate (hco3) reaction to form calcite (CaCO3).
# Models bicarbonate injection following calcium injection, so that a
# moving reaction front forms a calcite precipitation zone. As the front moves,
# the upstream side of the front continues to form calcite via precipitation,
# while at the downstream side, dissolution of the solid calcite occurs.
#
# The reaction network considered is as follows:
# Aqueous equilibrium reactions:
# a)  h+ + hco3- = CO2(aq),             Keq = 10^(6.341)
# b)  hco3- = h+ + CO23-,               Keq = 10^(-10.325)
# c)  ca2+ + hco3- = h+ + CaCO3(aq),    Keq = 10^(-7.009)
# d)  ca2+ + hco3- = cahco3+,           Keq = 10^(-0.653)
# e)  ca2+ = h+ + CaOh+,                Keq = 10^(-12.85)
# f)  - h+ = oh-,                       Keq = 10^(-13.991)
#
# Kinetic reactions
# g)  ca2+ + hco3- = h+ + CaCO3(s),     A = 0.461 m^2/L, k = 6.456542e-2 mol/m^2 s,
#                                       Keq = 10^(1.8487)
#
# The primary chemical species are h+, hco3- and ca2+. The pressure gradient is fixed,
# and a conservative tracer is also included.
#
# This example is taken from:
# Guo et al, A parallel, fully coupled, fully implicit solution to reactive
# transport in porous media using the preconditioned Jacobian-Free Newton-Krylov

# Tests that energy conservation is satisfied in 1-phase flow when there are
# multiple heat structures are connected to the same pipe.
#
# This problem has 2 heat structures with different material properties and
# initial conditions connected to the same flow channel, which has solid wall
# boundary conditions at both ends. An ideal gas equation of state is used for
# the fluid:
#   e(T) = cv * T
# From energy conservation, an analytic expression for the steady-state
# temperature results:
#   (rho(p,T)*e(T)*V)_fluid + (rho*cp*T*V)_hs1 + (rho*cp*T*V)_hs2 = constant
# The following are constant:
#   V_i         domain volumes for flow channel and heat structures
#   rho_fluid   fluid density (due to conservation of mass)
#   rho_hsi     heat structure densities
#   cp_hsi      heat structure specific heats
# Furthermore, all volumes are set equal to 1. Therefore the expression for the
# steady-state temperature is the following:
#   T = E0 / C0
# where
#   E0 = (rho(p0,T0)*e(T0))_fluid + (rho*cp*T0)_hs1 + (rho*cp*T0)_hs2
#   C0 = (rho(p0,T0)*cv)_fluid + (rho*cp)_hs1 + (rho*cp)_hs2
#
# An ideal gas is defined by (gamma, R), and the relation between R and cv is as
# follows:
#   cp = gamma * R / (gamma - 1)
#   cv = cp / gamma = R / (gamma - 1)
# For the EOS parameters
#   gamma = 1.0001
#   R = 100 J/kg-K
# the relevant specific heat is
#   cv = 1e6 J/kg-K
#
# For the initial conditions
#   p = 100 kPa
#   T = 300 K
# the density and specific internal energy should be
#   rho = 3.3333333333333 kg/m^3
#   e = 300000000 J/kg
#
# The following heat structure parameters are used:
#   T0_hs1 = 290 K           T0_hs2 = 310 K
#   rho_hs1 = 8000 kg/m^3    rho_hs2 = 6000 kg/m^3
#   cp_hs1 = 500 J/kg-K      cp_hs2 = 600 J/kg-K
#
# E0 = 1e9 + 8000 * 500 * 290 + 6000 * 600 * 310
#    = 3276000000 J
# C0 = 3.3333333333333e6 + 8000 * 500 + 6000 * 600
#    = 10933333.3333333 J/K
# T = E0 / C0
#   = 3276000000 / 10933333.3333333

# Large strain/rotation test for shell elements

# A cantilever beam that is 40 m long (Y direction) with 1 m x 1 m
# cross-section is modeled using 5 shell elements placed along its
# length. The bottom boundary is fixed in all displacements and
# rotations. A load of 0.140625 N is applied at each node on the top
# boundary, resulting in a total load of 0.28125 N. E = 1800 Pa and
# v = 0.0.

# The reference solution for large deflection of this beam is based on
# K. E. Bisshopp and D.C. Drucker, Quaterly of Applied Mathematics,
# Vol 3, No. # 3, 1945.

# For PL^2/EI = 3, disp_z at tip = 0.6L = 24 m & disp_y at tip = 0.76*L-L = -9.6 m

# The FEM solution at tip of cantilever is:
# disp_z = 24.85069 m; relative error = 3.54 %
# disp_y = -9.125937 m; relative error = 5.19 %

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

# fully-saturated situation with a poly-line sink at one
# of the nodes.  Because there is no fluid flow, the
# other nodes should not experience any change in
# porepressure.
# The poly-line sink has length=2 and weight=0.1, and
# extracts fluid at a constant rate of 1 kg.m^-1.s^-1.
# Therefore, in 1 second it will have extracted a total
# of 0.2 kg.
# The porosity is 0.1, and the elemental volume is 2,
# so the fluid mass at the node in question = 0.2 * density / 4,
# where the 4 is the number of nodes in the element.
# In this simulation density = dens0 * exp(P / bulk), with
# dens0 = 100, and bulk = 20 MPa.
# The initial porepressure P0 = 10 MPa, so the final (after
# 1 second of simulation) is

# 2 beams of length 1m are fixed at one end and a force of 1e-4 N
# is applied at the other end of the beams. Beam 1 is in block 1
# and beam 2 is in block 2. All the material properties for the two
# beams are identical. The moment of inertia of beam 2 is twice that

# P = t
# With the Biot coefficient being 1, the effective stresses should be
# stress_xx = stress_yy = stress_zz = t
# With bulk modulus = 1 then should have
# vol_strain = strain_xx + strain_yy + strain_zz = t.

# With the biot coefficient being 1, the porosity (phi) # at time t is:

# checking jacobian for 3-plane linear plasticity using SimpleTester.
#
# This is like the test multi/three_surface14.i
# Plasticity models:
# SimpleTester0 with a = 0 and b = 1 and strength = 1
# SimpleTester1 with a = 1 and b = 0 and strength = 1
# SimpleTester2 with a = 1 and b = 1 and strength = 3

#
# trial stress_yy = 0.15 and stress_zz = 1.5
#
# trial stress_yy = 2.1 and stress_zz = 3.0
#
# Then all three will be active, but there is linear-dependence.
# SimpleTester1 will turn off, since it is closest,
# and the algorithm will return to stress_zz=1, stress_yy=2, but
# then SimpleTester1 will be positive, so it will be turned back
# on, and then SimpleTester0 or SimpleTester2 will be turned off
# (a random choice will be made).
# If SimpleTester2 is turned
# off then algorithm returns to stress_zz=1=stress_yy, but then
# SimpleTester2 violates Kuhn-Tucker (f<0 and pm>0), so the algorithm
# will restart, and return to stress_zz=1=stress_yy, with internal0=2
# and internal1=1.1
# If SimpleTester0 is turned off then the algorithm will return to
# stress_zz=2, stress_yy=1, where f0>0.  Once again, a random choice
# of turning off SimpleTester1 or SimpleTester2 can be made.  Hence,
# oscillations can occur.  If too many oscillations occur then the algorithm
# will fail

# Test to verify the fundamental natural frequency of a one element ADComputeShellStress
# BCs: Clamped on one end, free on others.
# Initial perturbation applied to edge of the beam. After that, the shell vibrates freely.
#
# Results have been compared for various thicknesses with the following approximate Results
# (Moose results were obtained with 8 elements along the length)
# Thickness = 0.1. Reference freq: 10.785 Hz, Moose freq: 10.612 Hz
# Thickness = 0.05. Reference freq: 5.393 Hz, Moose freq: 5.335 Hz
# Thickness = 0.025. Reference freq: 2.696 Hz, Moose freq: 2.660 Hz
#
# Reference values have been obtained from Robert Blevins, "Formulas for Dynamics, Acoustics and Vibration",
# Table 5.3 case 11. Formula looks like: f = lambda^2/(2*pi*a^2) * sqrt(E*h^2/(12*(1-nu*nu))), where lambda
# changes as a function of shell dimensions.

# This test uses one single element for speed reasons.

# Here, the shell, instead of being on the XY plane, is oriented at a 45 deg. angle
# with respect to the Y axis.

# Test for small strain euler beam vibration in y direction
# Test uses NodalGravity instead of UserForcingFunctionNodalKernel to apply the
# force.

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass = 0.01899772 at the cantilever end
# mass = 2.0 at the fixed end (just for file testing purposes does not alter result)

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25

# This implies that the corresponding time period of this beam is 4s.

# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.

# The time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y                vel_y                accel_y
# 0.0    0.0                   0.0                  0.0

#
# Rotation Test
#
# This test is designed to compute stress based on uniaxial strain
# and then follow that stress as the mesh is rotated 90 degrees.
#
# The mesh is composed of one block with a single element.  The nodal
# displacements in the three directions are prescribed.  Poisson's
# ratio is 1/3, and Young's modulus is 1e6.
#
# This test is mentioned in
# K. Kamojjala, R. Brannon, A. Sadeghirad, and J. Guilkey, "Verification
#   tests in solid mechanics," Engineering with Computers, Vol. 31, 2015.

# Test for small strain euler beam vibration in y direction
# The velocity and acceleration AuxVariables and the corresponding AuxKernels
# are set up using the LineElementAction using add_dynamic_variables. The action
# also creates the displacement variables, stress divergence kernels and
# beam strain. NodalTranslationalInertia is not created by the action.

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25

# This implies that the corresponding time period of this beam is 4s.

# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.

# The time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y                vel_y                accel_y
# 0.0    0.0                   0.0                  0.0

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 5ft (60 in).
# The beam is massless with a lumped mass at the end of the beam of 5000 lb
# The properties of the cantilever beam are as follows:
# E = 1e7 and I = 120 in^4
# Assuming a square cross section A = sqrt(12 * I) = 37.95
# Shear modulus (G) = 3.846e6
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 1.0
# mass (m) = 5000 lb / 386 = 12.95

# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 5.71 cps

# This implies that the corresponding time period of this beam is 0.175 s.

# The FEM solution for this beam with 10 elements gives
# a time period of 0.175 s with time step of 0.005 s.

# The sample is a single unit element, with fixed displacements on
# all sides.  A heat source of strength S (J/m^3/s) is applied into
# the element.  There is no fluid flow or heat flow.  The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5
# rock_thermal_exp = 0.25
# rock_density = 5
# rock_heat_capacity = 0.2

# Large strain/large rotation cantilever beam test

# A 300 N point load is applied at the end of a 4 m long cantilever beam.
# Young's modulus (E) = 1e4
# Shear modulus (G) = 1e8
# Poisson's ratio (nu) = -0.99995
# shear coefficient (k) = 1.0
# Area (A) = 1.0
# Iy = Iz = 0.16

# The dimensionless parameter alpha = kAGL^2/EI = 1e6
# Since the value of alpha ia quite high, the beam behaves like
# a thin beam where shear effects are not significant.

# Beam deflection:
# small strain+rot = 3.998 m (exact 4.0)
# large strain + small rotation = -0.05 m in x and 3.74 m in z
# large rotations + small strain = -0.92 m in x and 2.38 m in z
# large rotations + large strain = -0.954 m in x and 2.37 m in z (exact -1.0 m in x and 2.4 m in z)

# Test for small strain timoshenko beam bending in y direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.00027846257
# Poisson's ratio (nu) = 0.3
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 204.3734

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = 5.868e-4 m

# Using 10 elements to discretize the beam element, the FEM solution is 5.852e-2m.
# This deflection matches the FEM solution given in Prathap and Bhashyam (1982).

# References:
# Prathap and Bhashyam (1982), International journal for numerical methods in engineering, vol. 18, 195-210.
# Note that the force is scaled by 1e-4 compared to the reference problem.

# Jacobian check for nonlinear, multi-surface plasticity.
# Returns to an edge of the tensile yield surface
# This is a very nonlinear test and a delicate test because it perturbs around
# an edge of the yield function where some derivatives are not well defined
#
# Plasticity models:
# Mohr-Coulomb with cohesion = 40MPa, friction angle = 35deg, dilation angle = 5deg
# Tensile with strength = 1MPa
#
# Lame lambda = 1GPa.  Lame mu = 1.3GPa
#
# NOTE: The yield function tolerances here are set at 100-times what i would usually use
# This is because otherwise the test fails on the 'pearcey' architecture.
# This is because identical stress tensors yield slightly different eigenvalues
# (and hence return-map residuals) on 'pearcey' than elsewhere, which results in
# a different number of NR iterations are needed to return to the yield surface.
# This is presumably because of compiler internals, or the BLAS routines being
# optimised differently or something similar.

# fully-saturated situation with a poly-line sink with use_mobility=true
# The poly-line consists of 2 points, and has a length
# of 0.5.  Each point is weighted with a weight of 0.1
# The PorousFlowPolyLineSink has
# p_or_t_vals = 0 1E7
# fluxes = 0 1
# so that for 0<=porepressure<=1E7
# base flux = porepressure * 1E-6 * mobility  (measured in kg.m^-1.s^-1),
# and when multiplied by the poly-line length, and
# the weighting of each point, the mass flux is
# flux = porepressure * 0.5*E-8 * mobility (kg.s^-1).
#
# The fluid and matrix properties are:
# porosity = 0.1
# element volume = 8 m^3
# density = dens0 * exp(P / bulk), with bulk = 2E7
# initial porepressure P0 = 1E7
# viscosity = 0.2
# So, fluid mass = 0.8 * density (kg)
#
# The equation to solve is
# d(Mass)/dt = - porepressure * 0.5*E-8 * density / viscosity
#
# PorousFlow discretises time to conserve mass, so to march
# forward in time, we must solve
# Mass(dt) = Mass(0) - P * 0.5E-8 * density / viscosity * dt
# or
# 0.8 * dens0 * exp(P/bulk) = 0.8 * dens0 * exp(P0/bulk) - P * 0.5E-8 * density / viscosity * dt
# For the numbers written above this gives
# P(t=1) = 6.36947 MPa

# Uses a multi-smooted version of Mohr-Coulomb (via CappedMohrCoulombStressUpdate and ComputeMultipleInelasticStress) to simulate the following problem.
# A cubical block is notched around its equator.
# All of its outer surfaces have roller BCs, but the notched region is free to move as needed
# The block is initialised with a high hydrostatic tensile stress
# Without the notch, the BCs do not allow contraction of the block, and this stress configuration is admissible
# With the notch, however, the interior parts of the block are free to move in order to relieve stress, and this causes plastic failure
# The top surface is then pulled upwards (the bottom is fixed because of the roller BCs)
# This causes more failure

# Checking the Jacobian of Flux-Limited TVD Advection, 2 phases, 2 components, using flux_limiter_type != None
#
# Here we use snes_check_jacobian instead of snes_type=test.  The former just checks the Jacobian for the
# random initial conditions, while the latter checks for u=1 and u=-1
#
# The Jacobian is correct for u=1 and u=-1, but the finite-difference scheme used by snes_type=test gives the
# wrong answer.
# For u=constant, the Kuzmin-Turek scheme adds as much antidiffusion as possible, resulting in a central-difference
# version of advection (flux_limiter = 1).  This is correct, and the Jacobian is calculated correctly.
# However, when computing the Jacobian using finite differences, u is increased or decreased at a node.
# This results in that node being at a maximum or minimum, which means no antidiffusion should be added
# (flux_limiter = 0).  This corresponds to a full-upwind scheme.  So the finite-difference computes the
# Jacobian in the full-upwind scenario, which is incorrect (the original residual = 0, after finite-differencing
# the residual comes from the full-upwind scenario).

# Testing StickyBC
#
# Push the bottom of an element upward until the top hits an (invisible) obstruction.
# 10 timesteps are used.  In each timestep disp_y is increased by 0.1.  The
# StickyBC has a max_value of 0.49, so at timestep 5 this bound will be violated
# and the top boundary will be fixed forever after.
#
# This test also illustrates that StickyBC is only ever meant to be used in
# special situations:
# - if, after the simulation ends, the bottom is moved downward again, the StickyBC
#   will keep the top fixed.  Ie, the StickyBC is truly "sticky".
# - setting max_value = 0.5 in this test illustrates the "approximate" nature
#   of StickyBC, in that some nodes will be fixed at disp_y=0.5, while others
#   will be fixed at disp_y=0.6, due to the timestepping and roundoff errors
#   in MOOSE's solution.

# Checking the Jacobian of Flux-Limited TVD Advection, 1 phase, 1 component, unsaturated, using flux_limiter_type != none
# This is quite a heavy test, but we need a fairly big mesh to check the flux-limiting+TVD is happening correctly
#
# Here we use snes_check_jacobian instead of snes_type=test.  The former just checks the Jacobian for the
# random initial conditions, while the latter checks for u=1 and u=-1
#
# The Jacobian is correct for u=1 and u=-1, but the finite-difference scheme used by snes_type=test gives the
# wrong answer.
# For u=constant, the Kuzmin-Turek scheme adds as much antidiffusion as possible, resulting in a central-difference
# version of advection (flux_limiter = 1).  This is correct, and the Jacobian is calculated correctly.
# However, when computing the Jacobian using finite differences, u is increased or decreased at a node.
# This results in that node being at a maximum or minimum, which means no antidiffusion should be added
# (flux_limiter = 0).  This corresponds to a full-upwind scheme.  So the finite-difference computes the
# Jacobian in the full-upwind scenario, which is incorrect (the original residual = 0, after finite-differencing
# the residual comes from the full-upwind scenario).

# Identical to pp_generation_unconfined_fullysat_volume.i but using an Action
#
# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable.  Fluid is pumped into the sample via a
# volumetric source (ie m^3/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/s.  Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz   (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz   (remember this is effective stress)
#
# In standard porous_flow, everything is based on mass, eg the source has
# units kg/s/m^3.  This is discussed in the other pp_generation_unconfined
# models.  In this test, we use the FullySaturated Kernel and set
# multiply_by_density = false
# meaning the fluid Kernel has units of volume, and the source, s, has units 1/time
#
# The ratios are:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t
# stress_zz = (2 + 4*shear/3)*0.612245*s*t = 2.44898*s*t

# Plasticity models:
# SimpleTester0 with a = 0 and b = 1 and strength = 1
# SimpleTester1 with a = 1 and b = 0 and strength = 1
# SimpleTester2 with a = 1 and b = 1 and strength = 3

# trial stress_yy = 2.1 and stress_zz = 3.0

# This is similar to three_surface14.i, and a description is found there.

# A fracture, which is a 1D line of elements, is embedded in a matrix, which is a 2D surface of elements.
# The meshes conform: all fracture nodes are also matrix nodes (the fracture elements are sides of matrix elements).
# The overall mesh has two blocks, named "matrix" and "fracture".
#
# Two variables are defined:
# - frac_T, which is the temperature inside the fracture;
# - matrix_T, which is the temperature in the matrix.
# frac_T is governed by a diffusion equation along the 1D fracture.
# matrix_T is governed by a diffusion equation in the 2D matrix, with small diffusion coefficient.
# Heat is exchanged between the two systems via a heat-transfer coefficient, defined on the fracture subdomain, using two PorousFlowHeatMassTransfer Kernels
#
# If the mesh is too coarse, overshoots and undershoots in matrix_T can be observed.

# Test to verify the fundamental natural frequency of a one element ADComputeShellStress
# BCs: Clamped on one end, free on others.
# Initial perturbation applied to edge of the beam. After that, the shell vibrates freely.
#
# Results have been compared for various thicknesses with the following approximate Results
# (Moose results were obtained with 8 elements along the length)
# Thickness = 0.1. Reference freq: 10.785 Hz, Moose freq: 10.612 Hz
# Thickness = 0.05. Reference freq: 5.393 Hz, Moose freq: 5.335 Hz
# Thickness = 0.025. Reference freq: 2.696 Hz, Moose freq: 2.660 Hz
#
# Reference values have been obtained from Robert Blevins, "Formulas for Dynamics, Acoustics and Vibration",
# Table 5.3 case 11. Formula looks like: f = lambda^2/(2*pi*a^2) * sqrt(E*h^2/(12*(1-nu*nu))), where lambda
# changes as a function of shell dimensions.

# This test uses one single element for speed reasons.

# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material.  An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step.  After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
#     6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

# This test is also designed to be used to identify problems with restart files

# A cubical block is notched around its equator.
# All of its outer surfaces have roller BCs, but the notched region is free to move as needed
# The block is initialised with a high hydrostatic tensile stress
# Without the notch, the BCs do not allow contraction of the block, and this stress configuration is admissible
# With the notch, however, the interior parts of the block are free to move in order to relieve stress, and this causes plastic failure

# Simple equilibrium reaction example to illustrate the use of the AqueousEquilibriumReactions
# action.
# In this example, two primary species a and b are transported by diffusion and convection
# from the left of the porous medium, reacting to form two equilibrium species pa2 and pab
# according to the equilibrium reaction specified in the AqueousEquilibriumReactions block as:
#
#      reactions = '2a = pa2     2
#                   a + b = pab -2'
#
# where the 2 is the weight of the equilibrium species, the 2 on the RHS of the first reaction
# refers to the equilibrium constant (log10(Keq) = 2), and the -2 on the RHS of the second
# reaction equates to log10(Keq) = -2.
#
# This example is identical to 2species.i, except that it explicitly includes all AuxKernels
# and Kernels that are set up by the action in 2species.i

# Strata deformation and fracturing around a coal mine
#
# A 2D geometry is used that simulates a transverse section of
# the coal mine.  The model is actually 3D, but the "x"
# dimension is only 10m long, meshed with 1 element, and
# there is no "x" displacement.  The mine is 300m deep
# and just the roof is studied (0<=z<=300).  The model sits
# between 0<=y<=450.  The excavation sits in 0<=y<=150.  This
# is a "half model": the boundary conditions are such that
# the model simulates an excavation sitting in -150<=y<=150
# inside a model of the region -450<=y<=450.  The
# excavation height is 3m (ie, the excavation lies within
# 0<=z<=3).  Mining is simulated by moving the excavation's
# roof down, until disp_z=-3 at t=1.
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions are:
#  - disp_x = 0 everywhere
#  - disp_y = 0 at y=0 and y=450
#  - disp_z = 0 for y>150
#  - disp_z = -3 at maximum, for 0<=y<=150.  See excav function.
# That is, rollers on the sides, free at top, and prescribed at bottom.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = -0.025*(300-z) MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Below you will see Drucker-Prager parameters and AuxVariables, etc.
# These are not actally used in this example.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# Weak-plane cohesion = 0.1 MPa
# Weak-plane friction angle = 20 deg
# Weak-plane dilation angle = 10 deg
# Weak-plane tensile strength = 0.1 MPa
# Weak-plane compressive strength = 100 MPa, varying down to 1 MPa when tensile strain = 1

# This test is designed to compute a uniaxial stress and then follow that
# stress as the mesh is rotated 90 degrees.
#
# The mesh is composed of one block with a single element.  The nodal
# displacements in the x and y directions are prescribed.  Poisson's
# ratio is zero.

# Simple equilibrium reaction example to illustrate the use of the AqueousEquilibriumReactions
# action.
# In this example, two primary species a and b are transported by diffusion and convection
# from the left of the porous medium, reacting to form two equilibrium species pa2 and pab
# according to the equilibrium reaction specified in the AqueousEquilibriumReactions block as:
#
#      reactions = '2a = pa2     2
#                   a + b = pab -2'
#
# where the 2 is the weight of the equilibrium species, the 2 on the RHS of the first reaction
# refers to the equilibrium constant (log10(Keq) = 2), and the -2 on the RHS of the second
# reaction equates to log10(Keq) = -2.
#
# The AqueousEquilibriumReactions action creates all the required kernels and auxkernels
# to compute the reaction given by the above equilibrium reaction equation.
#
# Specifically, it adds to following:
# * An AuxVariable named 'pa2' (given in the reactions equations)
# * An AuxVariable named 'pab' (given in the reactions equations)
# * A AqueousEquilibriumRxnAux AuxKernel for each AuxVariable with all parameters
# * A CoupledBEEquilibriumSub Kernel for each primary species with all parameters
# * A CoupledDiffusionReactionSub Kernel for each primary species with all parameters
# * A CoupledConvectionReactionSub Kernel for each primary species with all parameters if
# pressure is a coupled variable

# Test for displacement of pinched cylinder
# Ref: Figure 10 and Table 6 from Dvorkin and Bathe, Eng. Comput., Vol. 1, 1984.

# A cylinder of radius 1 m and length 2 m (along Z axis) with clamped ends
# (at z = 0 and 2 m) is pinched at mid-length by placing point loads of 10 N
# at (1, 0, 1) and (-1, 0, 1). Due to the symmetry of the problem, only 1/8th
# of the cylinder needs to be modeled.

# The normalized series solution for the displacement at the loading point is
# w = Wc E t / P = 164.24; where Wc is the displacement in m, E is the Young's
# modulus, t is the thickness and P is the point load.

# For this problem, E = 1e6 Pa, L = 2 m, R = 1 m, t = 0.01 m, P = 10 N and
# Poisson's ratio = 0.3. This gives an analytic displacement of 0.16424 m.
# FEM results from different mesh discretizations are presented below. Only
# the 10x10 mesh is included as a test.

# As shown in the table below, the results from the MOOSE FEM analysis converge
# to the analytic solution and the convergence matches well with the results
# of Dvorkin and Bathe (1984).

# This problem consists of two beams with different prescribed temperatures on
# the top of the top beam and the bottom of the bottom beam.  The top beam is
# fixed against vertical displacement on the top surface, and the bottom beam
# bends downward due to thermal expansion.

# This is a test of the effectiveness of the Jacobian terms coupling temperature
# and displacement for thermal contact. The Jacobian is not exactly correct,
# but is close enough that this challenging problem converges in a small number
# of nonlinear iterations using NEWTON.

# Example of reactive transport model with dissolution of dolomite
#
# The equilibrium system has 5 primary species (Variables) and
# 5 secondary species (PorousFlowMassFractionAqueousEquilibrium).
# Some of the equilibrium constants have been chosen rather arbitrarily.
#
# Equilibrium reactions
# H+  + HCO3-                      = CO2(aq)
# -H+ + HCO3-                      = CO32-
#       HCO3- + Ca2+               = CaHCO3+
#       HCO3-        + Mg2+        = MgHCO3+
#       HCO3-               + Fe2+ = FeHCO3+
#
# The kinetic reaction that dissolves dolomite involves all 5 primary species.
#
# -2H+ + 2HCO3- + Ca2+ + 0.8Mg2+ + 0.2Fe2+ = CaMg0.8Fe0.2(CO3)2
#
# The initial concentration of precipitated dolomite is high, so it starts
# to dissolve immediately, increasing the concentrations of the primary species.
#
# Only single-phase, fully saturated physics is used.
# The pressure gradient is fixed, so that the Darcy velocity is 0.1m/s.
#
# Primary species are injected from the left side, and they flow to the right.
# Less dolomite dissolution therefore occurs on the left side (where
# the primary species have higher concentration).
#
# This test is more fully documented in tutorial_13

# An undrained oedometer test on a saturated poroelastic sample.
#
# The sample is a single unit element, with roller BCs on the sides
# and bottom.  A constant displacement is applied to the top: disp_z = -0.01*t.
# There is no fluid flow.
#
# Under these conditions
# porepressure = -(Biot coefficient)*(Biot modulus)*disp_z/L
# stress_xx = (bulk - 2*shear/3)*disp_z/L (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*disp_z/L (remember this is effective stress)
# where L is the height of the sample (L=1 in this test)
#
# Parameters:
# Biot coefficient = 0.3
# Porosity = 0.1
# Bulk modulus = 2
# Shear modulus = 1.5
# fluid bulk modulus = 1/0.3 = 3.333333
# 1/Biot modulus = (1 - 0.3)*(0.3 - 0.1)/2 + 0.1*0.3 = 0.1. BiotModulus = 10
#
# Desired output:
# zdisp = -0.01*t
# p0 = 0.03*t
# stress_xx = stress_yy = -0.01*t

# the result (below) will end up being plane stress (stress_yy=0):
# u_x = Axz
# u_y = Dzy
# u_z = -(A/2)x^2 + (D/2)(z^2-y^2)
# wc_x = -Dy
# wc_y = Ax
# wc_z = 0
# Here A and D are arbitrary constants.
# This results in strains being symmetric, and the only
# nonzero ones are
# ep_xx = Az
# ep_yy = Dz
# ep_zz = Dz
# kappa_xy = -D
# kappa_yx = A
# Then choosing D = -poisson*A gives, for layered Cosserat:
# stress_xx = EAz
# m_yx = (1-poisson^2)*A*B = (1/12)EAh^2 (last equality for joint_shear_stiffness=0)
# where h is the layer thickness.  All other stress and moment-stress
# components are zero.
# The test uses: E=1.2, poisson=0.3, A=1.11E-2, h=2

# Mandel's problem of consolodation of a drained medium
# Using the FullySaturatedDarcyBase and FullySaturatedFullySaturatedMassTimeDerivative kernels
# with multiply_by_density = false, so that this problem becomes linear
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed.  The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width.  a = 1
# Soil height.  b = 0.1
# Soil's Lame lambda.  la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = G = 0.75
# Soil bulk modulus.  K = la + 2*mu/3 = 1
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance.  1/K = 1
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient.  B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Consolidation coefficient.  c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top.  F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here

# Uses an unsmoothed version of capped-Mohr-Coulomb (via ComputeMultiPlasticityStress with SolidMechanicsPlasticTensileMulti and SolidMechanicsPlasticMohrCoulombMulti) to simulate the following problem.
# A cubical block is notched around its equator.
# All of its outer surfaces have roller BCs, but the notched region is free to move as needed
# The block is initialised with a high hydrostatic tensile stress
# Without the notch, the BCs do not allow contraction of the block, and this stress configuration is admissible
# With the notch, however, the interior parts of the block are free to move in order to relieve stress, and this causes plastic failure
# The top surface is then pulled upwards (the bottom is fixed because of the roller BCs)
# This causes more failure

# Using the results from the equilibrium run to provide the initial condition for
# porepressure, we now inject a gas phase into the brine-saturated reservoir. In this
# example, the mesh is not identical to the mesh used in gravityeq.i. Rather, it is
# generated so that it is more refined near the injection boundary and at the top of
# the model, as that is where the gas plume will be present.
#
# To use the hydrostatic pressure calculated using the gravity equilibrium run as the initial
# condition for the pressure, a SolutionUserObject is used, along with a SolutionFunction to
# interpolate the pressure from the gravity equilibrium run to the initial condition for liqiud
# porepressure in this example.
#
# Even though the gravity equilibrium is established using a 2D mesh, in this example,
# we use a mesh shifted 0.1 m to the right and rotate it about the Y axis to make a 2D radial
# model.
#
# Methane injection takes place over the surface of the hole created by rotating the mesh,
# and hence the injection area is 2 pi r h. We can calculate this using an AreaPostprocessor,
# and then use this in a ParsedFunction to calculate the injection rate so that 10 kg/s of
# methane is injected.
#
# Note: as this example uses the results from a previous simulation, gravityeq.i MUST be
# run before running this input file.

# SLKKS two phase example for the BCC and SIGMA phases. The sigma phase contains
# multiple sublattices. Free energy from
# Jacob, Aurelie, Erwin Povoden-Karadeniz, and Ernst Kozeschnik. "Revised thermodynamic
# description of the Fe-Cr system based on an improved sublattice model of the sigma phase."
# Calphad 60 (2018): 16-28.
#
# In this simulation we solve only for the sublattice concentrations of the sigma phase
# (and consequently for the free energy of the sigma phase as function of total concentration.)
# The Cr concentration is prescribed as a linear gradient. This permits us to plot
# the free energies of the BCC and sigma phases.

# Patch Test

# This test is designed to compute constant xx, yy, zz, xy, yz, and xz
#  stress on a set of irregular hexes.  The mesh is composed of one
#  block with seven elements.  The elements form a unit cube with one
#  internal element.  There is a nodeset for each exterior node.

# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
#  The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
#  zx).  This gives a uniform strain/stress state for all six unique
#  tensor components.  This displacement is again applied in the second
#  step.

# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
#  modulus is 5e5 (G=E/2/(1+nu)).  Therefore, for the mechanical strain,
#
#  stress xx = 1e6 * 1e-6 = 1
#  stress yy = 1e6 * 2e-6 = 2
#  stress zz = 1e6 * 3e-6 = 3
#  stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
#             (2 * G   * gamma_xy / 2 = 2 * G * epsilon_xy)
#  stress yz = 2 * 5e5 * 2e-6 / 2 = 1
#  stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# Young's modulus is a function of temperature for this test.  The
#  temperature changes from 100 to 500.  The Young's modulus drops
#  due to that temperature change from 1e6 to 6e5.

# Poisson's ratio also is a function of temperature and changes from
#  0 to 0.25.

# At the end of the temperature ramp, E=6e5 and nu=0.25.  This gives
#  G=2.4e=5.  lambda=E*nu/(1+nu)/(1-2*nu)=2.4E5.  The final stress
#  is therefore

#  stress xx = 2.4e5 * 12e-6 + 2*2.4e5*2e-6 = 3.84
#  stress yy = 2.4e5 * 12e-6 + 2*2.4e5*4e-6 = 4.80
#  stress zz = 2.4e5 * 12e-6 + 2*2.4e5*6e-6 = 5.76
#  stress xy = 2 * 2.4e5 * 2e-6 / 2 = 0.48
#             (2 * G   * gamma_xy / 2 = 2 * G * epsilon_xy)
#  stress yz = 2 * 2.4e5 * 4e-6 / 2 = 0.96
#  stress xz = 2 * 2.4e5 * 6e-6 / 2 = 1.44

# PorousFlowPeacemanBorehole with 2-phase, 3-components, with enthalpy, internal_energy, and thermal_conductivity
# NOTE: this test has suffered from repeated failures since its inception.  The problem always appears to be caused by having too many Dirac points in an element: see #10471.  As of Nov2020, the dirac7 DiracKernel uses only one Dirac point, not ten_points.bh.  One day it would be good to be able to use point_file = ten_points.bh

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam. The lumped
# mass also has a moment of inertia associated with it.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# Moment of inertia of lumped mass:
# Ixx = 0.2
# Iyy = 0.1
# Izz = 0.1
# mass proportional damping coefficient (eta) = 0.1

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The displacement time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y              vel_y               accel_y
# 0.0    0.0                 0.0                 0.0

# Strata deformation and fracturing around a coal mine
#
# A 2D geometry is used that simulates a transverse section of
# the coal mine.  The model is actually 3D, but the "x"
# dimension is only 10m long, meshed with 1 element, and
# there is no "x" displacement.  The mine is 300m deep
# and just the roof is studied (0<=z<=300).  The model sits
# between 0<=y<=450.  The excavation sits in 0<=y<=150.  This
# is a "half model": the boundary conditions are such that
# the model simulates an excavation sitting in -150<=y<=150
# inside a model of the region -450<=y<=450.  The
# excavation height is 3m (ie, the excavation lies within
# 0<=z<=3).  Mining is simulated by moving the excavation's
# roof down, until disp_z=-3 at t=1.
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions are:
#  - disp_x = 0 everywhere
#  - disp_y = 0 at y=0 and y=450
#  - disp_z = 0 for y>150
#  - disp_z = -3 at maximum, for 0<=y<=150.  See excav function.
# That is, rollers on the sides, free at top, and prescribed at bottom.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = -0.025*(300-z) MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Below you will see weak-plane parameters and AuxVariables, etc.
# These are not actally used in this example.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa, varying down to 1 MPa when tensile strain = 1

# Apply a piecewise-linear sink flux to the right-hand side and watch fluid flow to it
#
# This test has a single phase with two components.  The test initialises with
# the porous material fully filled with component=1.  The left-hand side is fixed
# at porepressure=1 and mass-fraction of the zeroth component being unity.
# The right-hand side has a very strong piecewise-linear flux that keeps the
# porepressure~0 at that side.  Fluid mass is extracted by this flux in proportion
# to the fluid component mass fraction.
#
# Therefore, the zeroth fluid component will flow from left to right (down the
# pressure gradient).
#
# The important DE is
# porosity * dc/dt = (perm / visc) * grad(P) * grad(c)
# which is true for c = mass-fraction, and very large bulk modulus of the fluid.
# For grad(P) constant in time and space (as in this example) this is just the
# advection equation for c, with velocity = perm / visc / porosity.  The parameters
# are chosen to velocity = 1 m/s.
# In the numerical world, and especially with full upwinding, the advection equation
# suffers from diffusion.  In this example, the diffusion is obvious when plotting
# the mass-fraction along the line, but the average velocity of the front is still
# correct at 1 m/s.
# This test uses the FullySaturated version of the flow Kernel.  This does not
# suffer from as much numerical diffusion as the standard PorousFlow Kernel since
# it does not employ any upwinding.

# Analytically, the displacements are
# wc_z = B sinh(w_e y)
# disp_x = (2 mu_c B / w_e / (mu + mu_c)) (1 - cosh(w_e y))
# with w_e^2 = 2 mu mu_c / be / (mu + mu_c)
# and B = arbitrary integration constant
#
# Also, the only nonzero stresses are
# m_zy = 2 B be w_e cosh(w_e y)
# si_yx = -4 mu mu_c/(mu + mu_c) B sinh(w_e y)
#
# MOOSE gives these stress components correctly.
# However, it also gives a seemingly non-zero si_xy
# component.  Upon increasing the resolution of the
# mesh (ny=10000, for example), the stress components
# are seen to limit correctly to the above forumlae
#
# I use mu = 2, mu_c = 3, be = 0.6, so w_e = 2
# Also i use B = 1, so at y = 1
# wc_z = 3.626860407847
# disp_x = -1.65731741465

# Checking the Jacobian of Flux-Limited TVD Advection, using flux_limiter_type = superbee
# Here we use snes_check_jacobian instead of snes_type=test.  The former just checks the Jacobian for the
# random initial conditions, while the latter checks for u=1 and u=-1
#
# The Jacobian is correct for u=1 and u=-1, but the finite-difference scheme used by snes_type=test gives the
# wrong answer.
# For u=1, the Kuzmin-Turek scheme adds as much antidiffusion as possible, resulting in a central-difference
# version of advection (flux_limiter = 1).  This is correct, and the Jacobian is calculated correctly.
# However, when computing the Jacobian using finite differences, u is increased or decreased at a node.
# This results in that node being at a maximum or minimum, which means no antidiffusion should be added
# (flux_limiter = 0).  This corresponds to a full-upwind scheme.  So the finite-difference computes the
# Jacobian in the full-upwind scenario, which is incorrect (the original residual = 0, after finite-differencing
# the residual comes from the full-upwind scenario).

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 3D geometry.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
#   where:
#          Pi = inner pressure
#          Po = outer pressure
#          ri = inner radius
#          ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000 at t = 1.0, respectively. The resulting compressive
# tangential stress is largest at the inner wall and, from the above equation, has a
# value of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

# PorousFlow simulation of injection and production in a 2D aquifer
# Much of this file is standard porous-flow stuff.  The unusual aspects are:
# - transfer of the rates of changes of each species (kg/s) to the aquifer_geochemistry.i simulation.  This is achieved by saving these changes from the PorousFlowMassTimeDerivative residuals
# - transfer of the temperature field to the aquifer_geochemistry.i simulation
# Interesting behaviour can be simulated by this file without its "parent" simulation, exchanger.i.  exchanger.i provides mass-fractions injected via the injection_rate_massfrac_* variables, but since these are more-or-less constant throughout the duration of the exchanger.i simulation, the initial_conditions specified below may be used.  Similar, exchanger.i provides injection_temperature, but that is also constant.

# Gravity Test
#
# This test is designed to exercise the gravity body force kernel.
#
# The mesh for this problem is a rectangular bar 10 units by 1 unit
#   by 1 unit.
#
# The boundary conditions for this problem are as follows.  The
#   displacement is zero on each of side that faces a negative
#   coordinate direction.  The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
#   elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note:  The simulation does not measure stress at x=0.  The stress
#   is reported at element centers.  The element closest to x=0 sits
#   at x = 1/4 and has a stress of 390.  This matches the linear
#   stress distribution that is expected.  The same situation applies
#   at x = L where the stress is zero analytically.  The nearest
#   element is at x=9.75 where the stress is 10.

# heat04, but using an action
#
# The sample is a single unit element, with fixed displacements on
# all sides.  A heat source of strength S (J/m^3/s) is applied into
# the element.  There is no fluid flow or heat flow.  The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0

#  contact using the penalty method.  In this test a sinusoidal
#  displacement is applied in the horizontal direction to simulate
#  a small block come in and out of contact as it slides down a larger block.
#
#  The sinusoid is of the form 0.4sin(4t)+0.2. The gold file is run
#  on one processor and the benchmark
#  case is run on a minimum of 4 processors to ensure no parallel variability
#  in the contact pressure and penetration results.  Further documentation can
#  found in moose/modules/contact/doc/sliding_block/

# is on the left. Fluid end is subjected to a 250Hz sine wave with a single peak.
# Structural domain has the same material properties as the fluid. Interface between
# structure and fluid is located at 5.0m in the x-direction. Fluid pressure is recorded
# at (5, 0.05, 0.05). Structural stress is also recorded at the same location. Fluid

# Jacobian check for nonlinear, multi-surface plasticity
# This returns to the edge of Mohr Coulomb.
# This is a very nonlinear test and a delicate test because it perturbs around
# an edge of the yield function where some derivatives are not well defined
#
# Plasticity models:
# Mohr-Coulomb with cohesion = 40MPa, friction angle = 35deg, dilation angle = 5deg
# Tensile with strength = 1MPa
#
# Lame lambda = 1GPa.  Lame mu = 1.3GPa
#
# NOTE: The yield function tolerances here are set at 100-times what i would usually use
# This is because otherwise the test fails on the 'pearcey' architecture.
# This is because identical stress tensors yield slightly different eigenvalues
# (and hence return-map residuals) on 'pearcey' than elsewhere, which results in
# a different number of NR iterations are needed to return to the yield surface.
# This is presumably because of compiler internals, or the BLAS routines being
# optimised differently or something similar.

# Note that we do not get u - ref = (u_0 - ref) * exp(-rate * t)
# because of the time discretisation.  We are solving
# the equation
# (u(t+dt) - u(t))/dt = -rate * (u(t+dt) - ref)
# which has solution
# u(t+dt) = (u(t) + rate * ref * dt) / (1 + rate * dt)
# With u(0)=2, rate=1.5, ref=1 and dt=0.2 we get

# Represents a unique Maxwell module with E = 10GPa and eta = 10 days with an imposed eigenstrain alpha = 0.001.
# The behavior is set up so that the creep strain is driven by both the elastic stress and the internal
# stress induced by the eigenstrain (E * alpha).
#
# In this test, the specimen is free of external stress (sigma = 0) so the creep deformation only derives from
# the eigenstrain. The total strain to be expected is:
#     epsilon = alpha * (1 + t / eta)
# Both the stress and the elastic strain are 0.

# Tests HeatStructure2DCoupler when the heat structures are separated by some
# distance. The first heat structure has a larger coupling surface than the
# second heat structure. The component will be used to model a given energy
# transfer rate per unit temperature difference [W/K]. This test checks that:
#   a) heat transfer occurs in the correct direction
#   b) energy is conserved
#
# With a goal of transferring 5 W/K and a temperature difference of 200 K, and
# a transient time of 10 seconds, ~10 kJ should be transferred. Note that this
# estimate will not be exact since the temperature difference changes slightly
# over the transient.

# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material.  An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step.  After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
#     6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

# This test is also designed to be used to identify problems with restart files

# Poroelastic response of a borehole.
#
# LOWRES VERSION: this version does not give perfect agreement with the analytical solution
#
# A fully-saturated medium contains a fluid with a homogeneous porepressure,
# but an anisitropic insitu stress.  A infinitely-long borehole aligned with
# the $$z$$ axis is instanteously excavated.  The borehole boundary is
# stress-free and allowed to freely drain.  This problem is analysed using
# plane-strain conditions (no $$z$$ displacement).
#
# The solution in Laplace space is found in E Detournay and AHD Cheng "Poroelastic response of a borehole in a non-hydrostatic stress field".  International Journal of Rock Mechanics and Mining Sciences and Geomechanics Abstracts 25 (1988) 171-182.  In the small-time limit, the Laplace transforms may be performed.  There is one typo in the paper.  Equation (A4)'s final term should be -(a/r)\sqrt(4ct/(a^2\pi)), and not +(a/r)\sqrt(4ct/(a^2\pi)).
#
# Because realistic parameters are chosen (below),
# the residual for porepressure is much smaller than
# the residuals for the displacements.  Therefore the
# scaling parameter is chosen.  Also note that the
# insitu stresses are effective stresses, not total
# stresses, but the solution in the above paper is
# expressed in terms of total stresses.
#
# Here are the problem's parameters, and their values:
# Borehole radius.  a = 1
# Rock's Lame lambda.  la = 0.5E9
# Rock's Lame mu, which is also the Rock's shear modulus.  mu = G = 1.5E9
# Rock bulk modulus.  K = la + 2*mu/3 = 1.5E9
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.125
# Rock bulk compliance.  1/K = 0.66666666E-9
# Fluid bulk modulus.  Kf = 0.7171315E9
# Fluid bulk compliance.  1/Kf = 1.39444444E-9
# Rock initial porosity.  phi0 = 0.3
# Biot coefficient.  alpha = 0.65
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 2E9
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.345E9
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.2364
# Skempton coefficient.  B = alpha*M/Ku = 0.554
# Fluid mobility (rock permeability/fluid viscosity).  k = 1E-12

# Poroelastic response of a borehole.
#
# HIGHRES VERSION: this version gives good agreement with the analytical solution, but it takes a while so is a "heavy" test
#
# A fully-saturated medium contains a fluid with a homogeneous porepressure,
# but an anisitropic insitu stress.  A infinitely-long borehole aligned with
# the $$z$$ axis is instanteously excavated.  The borehole boundary is
# stress-free and allowed to freely drain.  This problem is analysed using
# plane-strain conditions (no $$z$$ displacement).
#
# The solution in Laplace space is found in E Detournay and AHD Cheng "Poroelastic response of a borehole in a non-hydrostatic stress field".  International Journal of Rock Mechanics and Mining Sciences and Geomechanics Abstracts 25 (1988) 171-182.  In the small-time limit, the Laplace transforms may be performed.  There is one typo in the paper.  Equation (A4)'s final term should be -(a/r)\sqrt(4ct/(a^2\pi)), and not +(a/r)\sqrt(4ct/(a^2\pi)).
#
# Because realistic parameters are chosen (below),
# the residual for porepressure is much smaller than
# the residuals for the displacements.  Therefore the
# scaling parameter is chosen.  Also note that the
# insitu stresses are effective stresses, not total
# stresses, but the solution in the above paper is
# expressed in terms of total stresses.
#
# Here are the problem's parameters, and their values:
# Borehole radius.  a = 1
# Rock's Lame lambda.  la = 0.5E9
# Rock's Lame mu, which is also the Rock's shear modulus.  mu = G = 1.5E9
# Rock bulk modulus.  K = la + 2*mu/3 = 1.5E9
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.125
# Rock bulk compliance.  1/K = 0.66666666E-9
# Fluid bulk modulus.  Kf = 0.7171315E9
# Fluid bulk compliance.  1/Kf = 1.39444444E-9
# Rock initial porosity.  phi0 = 0.3
# Biot coefficient.  alpha = 0.65
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 2E9
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.345E9
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.2364
# Skempton coefficient.  B = alpha*M/Ku = 0.554
# Fluid mobility (rock permeability/fluid viscosity).  k = 1E-12

# This test checks whether the ComputeReducedOrderEigenstrain is functioning properly.
#
# If instead of 'reduced_eigenstrain', 'thermal_eigenstrain' is given to
# eigenstrain_names in the Physics/SolidMechanics/QuasiStatic/all block, the output will be
# quite different.
#
# Open the reducedOrderRZLinear_out_hydro_0001.csv file and plot the hydro variables as
# a function of x.  For the reduced order case, the values are smooth across each of the
# two elements with a jump upward from the left element to the right element.  However,
# when not using 'reduced_order_eigenstrain', a jump downward appears from the left
# element to the right element.

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable.  Fluid is pumped into the sample via a
# volumetric source (ie m^3/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/s.  Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz   (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz   (remember this is effective stress)
#
# In standard porous_flow, everything is based on mass, eg the source has
# units kg/s/m^3.  This is discussed in the other pp_generation_unconfined
# models.  In this test, we use the FullySaturated Kernel and set
# multiply_by_density = false
# meaning the fluid Kernel has units of volume, and the source, s, has units 1/time
#
# The ratios are:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)
#
# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t
# porepressure = 10*(s*t - 0.3*0.612245*s*t) = 8.163265*s*t
# stress_xx = (2 - 2*1.5/3)*0.612245*s*t = 0.612245*s*t

# Test that the upwinding works correctly.
#
# A poly-line sink sits at the centre of the element.
# It has length=4 and weight=0.5, and extracts fluid
# at a constant rate of
# (1 * relative_permeability) kg.m^-1.s^-1
# Since it sits at the centre of the element, it extracts
# equally from each node, so the rate of extraction from
# each node is
# (0.5 * relative_permeability) kg.s^-1
# including the length and weight effects.
#
# There is no fluid flow.
#
# The initial conditions are such that all nodes have
# relative_permeability=0, except for one which has
# relative_permeaility = 1.  Therefore, all nodes should
# remain at their initial porepressure, except the one.
#
# The porosity is 0.1, and the elemental volume is 2,
# so the fluid mass at the node in question = 0.2 * density / 4,
# where the 4 is the number of nodes in the element.
# In this simulation density = dens0 * exp(P / bulk), with
# dens0 = 100, and bulk = 20 MPa.
# The initial porepressure P0 = 10 MPa, so the final (after
# 1 second of simulation) is
# P(t=1) = 8.748592 MPa

# Illustrates desorption works as planned.
#
# A mesh contains 3 elements in arranged in a line.
# The central element contains desorped fluid.
# This desorps to the nodes of that element.
#
# In the central element, of volume V, the following occurs.
# The initial porepressure=1, and concentration=1.
# The initial mass of fluid is
# V * (2 * porosity * density + (1 - porosity) * concentration)
# = V * 1.289547
# Notice the factor of "2" in the porespace contribution:
# it is because the porepressure is evaluated at nodes, so
# the nodes on the exterior of the centre_block have
# nodal-volume contributions from the elements not in centre_block.
#
# The mass-conservation equation reads
# 2 * porosity * density + (1 - porosity) * concentration = 1.289547
# and the desorption equation reads
# d( (1-porosity)C )/dt = - (1/tau)(C - dens_L * P / (P_L + P))
# where C = concentration, P = porepressure, P_L = Langmuir pressure
# dens_L = Langmuir density, tau = time constant.
# Using the mass-conservation equation in the desorption equation
# yields a nonlinear equation of P.  For dt=1, and the numerical values
# given below this yields
# P = 1.83697
# and
# C = 0.676616
# The desired result is achieved by MOOSE

# Test for small strain Timoshenko beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2e4
# Shear modulus (G) = 1e4
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 1.0
# Iy = 1.0 = Iz
# Length (L)= 4 m
# density (rho) = 1.0

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 8
# Therefore, the beam behaves like a Timoshenko beam.

# The FEM solution for this beam with 100 elements give first natural period of 0.2731s with a time step of 0.005.
# The acceleration, velocity and displacement time histories obtained from MOOSE matches with those obtained from ABAQUS.

# Values from the first few time steps are as follows:
# time    disp_y                vel_y                 accel_y
# 0.0     0.0                   0.0                   0.0
# 0.005   2.5473249455812e-05   0.010189299782325     4.0757199129299

# 0.015   5.8611622914354e-05   0.0014129505884026    8.055380456145
# 0.02    6.766113649781e-05    0.0022068548449798   -7.7378187535141
# 0.025   7.8981810558437e-05   0.0023214147792709    7.7836427272305

# Note that the theoretical first frequency of the beam using Euler-Bernoulli theory is:
# f1 = 1/(2 pi) * (3.5156/L^2) * sqrt(EI/rho) = 4.9455

# This implies that the corresponding time period of this beam (under Euler-Bernoulli assumption) is 0.2022s.

# This shows that Euler-Bernoulli beam theory under-predicts the time period of a thick beam. In other words, the Euler-Bernoulli beam theory predicts a more compliant beam than reality for a thick beam.

# Using a two-phase system (see precipitation.i for the single-phase)
# The saturation and porosity are chosen so that the results are identical to precipitation.i
#
# The precipitation reaction
#
# a <==> mineral
#
# produces "mineral".  Using mineral_density = fluid_density, theta = 1 = eta, the DE is
#
# a' = -(mineral / (porosity * saturation))' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is negative for a > 0.25, ie precipitation for a(t=0) > 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
#   = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * (porosity * saturation)
#
# This test checks that (a + c / (porosity * saturation)) is time-independent, and that a follows the above solution
#
# Aside:
#    The exponential curve is not followed exactly because moose actually solves
#    (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#    which does not give an exponential exactly, except in the limit dt->0

# Test that the upwinding works correctly.
#
# A poly-line sink sits at the centre of the element.
# It has length=4 and weight=0.5, and extracts fluid
# at a constant rate of
# (1 * relative_permeability) kg.m^-1.s^-1
# Since it sits at the centre of the element, it extracts
# equally from each node, so the rate of extraction from
# each node is
# (0.5 * relative_permeability) kg.s^-1
# including the length and weight effects.
#
# There is no fluid flow.
#
# The initial conditions are such that all nodes have
# relative_permeability=0, except for one which has
# relative_permeaility = 1.  Therefore, all nodes should
# remain at their initial porepressure, except the one.
#
# The porosity is 0.1, and the elemental volume is 2,
# so the fluid mass at the node in question = 0.2 * density / 4,
# where the 4 is the number of nodes in the element.
# In this simulation density = dens0 * exp(P / bulk), with
# dens0 = 100, and bulk = 20 MPa.
# The initial porepressure P0 = 10 MPa, so the final (after
# 1 second of simulation) is
# P(t=1) = 8.748592 MPa

# Dynamic problem with plasticity.
# A column of material (not subject to gravity) has the z-displacement
# of its sides fixed, but the centre of its bottom side is pulled
# downwards.  This causes failure in the bottom elements.
#
# The problem utilises damping in the following way.
# The DynamicStressDivergenceTensors forms the residual
# integral  grad(stress) + zeta*grad(stress-dot)
#     = V/L * elasticity * (du/dx + zeta * dv/dx)
# where V is the elemental volume, and L is the length-scale,
# and u is the displacement, and v is the velocity.
# The InertialForce forms the residual
# integral  density * (accel + eta * velocity)
#     = V * density * (a + eta * v)
# where a is the acceleration.
# So, a damped oscillator description with both these
# kernels looks like
# 0 = V * (density * a + density * eta * v + elasticity * zeta * v / L^2 + elasticity / L^2 * u)
# Critical damping is when the coefficient of v is
# 2 * sqrt(density * elasticity / L^2)
# In the case at hand, density=1E4, elasticity~1E10 (Young is 16GPa),
# L~1 to 10 (in the horizontal or vertical direction), so this coefficient ~ 1E7 to 1E6.
# Choosing eta = 1E3 and zeta = 1E-2 gives approximate critical damping.
# If zeta is high then steady-state is achieved very quickly.
#
# In the case of plasticity, the effective stiffness of the elements
# is significantly less.  Therefore, the above parameters give
# overdamping.
#
# This simulation is a nice example of the irreversable and non-uniqueness
# of simulations involving plasticity.  The result depends on the damping
# parameters and the time stepping.

# Gravity Test
#
# This test is similar to the other gravity tests, but it also tests the
# capability in MaterialTensorAux to return the stress of a single,
# specified integration point, rather than the element average.
# To get the stress at a single integration point, set the parameter
# qp_select to the integration point number (i.e. 0-9 for a quad 8)
# in the AuxKernel
#
# The mesh for this problem is a unit square.
#
# The boundary conditions for this problem are as follows.  The
#   displacement is zero on each of side that faces a negative
#   coordinate direction.  The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*1*1/(2*1e6) = 0.00002.
#
# The analytic solution for the stress along the bar assuming linear
#   elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*1 = 40.
#
# Note:  The isoparametric coordinate for a quad8 (fourth order) element
# is: +/- 0.77459667 and 0.  For a 1 unit square with the edge of
# the element in the x = 0 plane, there would be an integration point
# at x_coordinate 0.5 - 0.5*0.77459667 (0.11270167), 0.5, and
# 0.50 + 0.5*0.77459667 (0.88729834).
#
# The corresponding stresses are:
#
# S(0.11270167) = 40(1-0.11270167) = 35.491933
# S(0.5) = 40(1-0.5) = 20
# S(0.88729834) = 40(1-0.88729834) = 4.5080664
#
# These stresses are a precise match to the simulation result.

# Strata deformation and fracturing around a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young's modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = 0.025*z MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1

# Apply a PorousFlowOutflowBC to the right-hand side and watch fluid flow to it
#
# This test has a single phase with two components.  The test initialises with
# the porous material fully filled with component=1.  The left-hand side is fixed
# at porepressure=1 and mass-fraction of the zeroth component being unity.
# The right-hand side has
# - porepressure fixed at zero via a DirichletBC: physically this removes component=1
#   to ensure that porepressure remains fixed
# - a PorousFlowOutflowBC for the component=0 to allow that component to exit the boundary freely
#
# Therefore, the zeroth fluid component will flow from left to right (down the
# pressure gradient).
#
# The important DE is
# porosity * dc/dt = (perm / visc) * grad(P) * grad(c)
# which is true for c = mass-fraction, and very large bulk modulus of the fluid.
# For grad(P) constant in time and space (as in this example) this is just the
# advection equation for c, with velocity = perm / visc / porosity.  The parameters
# are chosen to velocity = 1 m/s.
# In the numerical world, and especially with full upwinding, the advection equation
# suffers from diffusion.  In this example, the diffusion is obvious when plotting
# the mass-fraction along the line, but the average velocity of the front is still
# correct at 1 m/s.

# This is an example of implementation of the multi-phase, multi-order parameter
# grand potential based phase-field model described in Phys. Rev. E, 98, 023309
# (2018). It includes 3 phases with 1 grain of each phase. This example was used
# to generate the results shown in Fig. 3 of the paper.

# Tests that energy conservation is satisfied in 1-phase flow when there are
# multiple heat transfer components connected to the same pipe, using specified
# wall heat flux.
#
# This problem has 2 wall heat flux sources, each with differing parameters.
# Solid wall boundary conditions are imposed such that there should be no flow,
# and the solution should be spatially uniform. With no other sources, the
# energy balance is
#   (rho*e*A)^{n+1} = (rho*e*A)^n + dt * [(q1*P1) + (q2*P2)]
# Note that spatial integration is dropped here due to spatial uniformity, and
# E has been replaced with e since velocity should be zero.
#
# For the initial conditions
#   p = 100 kPa
#   T = 300 K
# the density and specific internal energy should be
#   rho = 1359.792245 kg/m^3
#   e = 1.1320645935e+05 J/kg
#
# With the following heat source parameters:
#   q1 = 10 MW/m^2     P1 = 0.2 m
#   q2 = 20 MW/m^2     P2 = 0.4 m
# and A = 1 m^2 and dt = 2 s, the new energy solution value should be
#   (rho*e*A)^{n+1} = 1359.792245 * 1.1320645935e+05 * 1 + 2 * (10e6 * 0.2 + 20e6 * 0.4)

# The sample is a single unit element, with roller BCs on the sides
# and bottom.  A constant displacement is applied to the top: disp_z = -0.01*t.
# There is no fluid flow.
# Fluid mass conservation is checked.
#
# Under these conditions
# porepressure = porepressure(t=0) - (Fluid bulk modulus)*log(1 - 0.01*t)
# stress_xx = (bulk - 2*shear/3)*disp_z/L (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*disp_z/L (remember this is effective stress)
# where L is the height of the sample (L=1 in this test)
#
# Parameters:
# Bulk modulus = 2
# Shear modulus = 1.5
# fluid bulk modulus = 0.5
# initial porepressure = 0.1
#
# Desired output:
# zdisp = -0.01*t
# p0 = 0.1 - 0.5*log(1-0.01*t)
# stress_xx = stress_yy = -0.01*t
# stress_zz = -0.04*t
#
# Regarding the "log" - it comes from preserving fluid mass

# Strata deformation and fracturing around a coal mine
#
# A 2D geometry is used that simulates a longitudinal section of
# the coal mine.  The model is actually 3D, but the "x"
# dimension is only 10m long, meshed with 1 element, and
# there is no "x" displacement.  The mine is 400m deep
# and just the roof is studied (0<=z<=400).  The model sits
# between -300<=y<=1800.  The excavation sits in 0<=y<=1500.  The
# excavation height is 3m (ie, the excavation lies within
# 0<=z<=3).
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this elastic simulation are:
#  - disp_x = 0 everywhere
#  - disp_y = 0 at y=-300 and y=1800
#  - disp_z = 0 at z=0, but there is a time-dependent
#               Young's modulus that simulates excavation
#  - wc_x = 0 at y=300 and y=1800.
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = -0.025*(300-z) MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa

# ---------------------------------------------------------------------------
# This test is designed to verify the variable elasticity tensor functionality in the
# ADComputeFiniteStrainElasticStress class with the elasticity_tensor_has_changed flag
# by varying the young's modulus with temperature. A constant strain is applied
# to the mesh in this case, and the stress varies with the changing elastic constants.
#
# Geometry: A single element cube in symmetry boundary conditions and pulled
#           at a constant displacement to create a constant strain in the x-direction.
#
# Temperature:  The temperature varies from 400K to 700K in this simulation by
#           100K each time step. The temperature is held constant in the last
#           timestep to ensure that the elasticity tensor components are constant
#           under constant temperature.
#
# Results: Because Poisson's ratio is set to zero, only the stress along the x
#          axis is non-zero.  The stress changes with temperature.
#

#
#    The tensor mechanics results align exactly with the analytical results above
#    when this test is run with ComputeIncrementalStrain.  When the test is
#    run with ComputeFiniteStrain, a 0.05% discrepancy between the analytical
#    strains and the simulation strain results is observed, and this discrepancy
#    is carried over into the calculation of the elastic stress.

# Apply a piecewise-linear sink flux to the right-hand side and watch fluid flow to it
#
# This test has a single phase with two components.  The test initialises with
# the porous material fully filled with component=1.  The left-hand side is fixed
# at porepressure=1 and mass-fraction of the zeroth component being unity.
# The right-hand side has a very strong piecewise-linear flux that keeps the
# porepressure~0 at that side.  Fluid mass is extracted by this flux in proportion
# to the fluid component mass fraction.
#
# Therefore, the zeroth fluid component will flow from left to right (down the
# pressure gradient).
#
# The important DE is
# porosity * dc/dt = (perm / visc) * grad(P) * grad(c)
# which is true for c = mass-fraction, and very large bulk modulus of the fluid.
# For grad(P) constant in time and space (as in this example) this is just the
# advection equation for c, with velocity = perm / visc / porosity.  The parameters
# are chosen to velocity = 1 m/s.
# In the numerical world, and especially with full upwinding, the advection equation
# suffers from diffusion.  In this example, the diffusion is obvious when plotting
# the mass-fraction along the line, but the average velocity of the front is still
# correct at 1 m/s.

# Strata deformation and fracturing around a coal mine
#
# A 2D geometry is used that simulates a transverse section of
# the coal mine.  The model is actually 3D, but the "x"
# dimension is only 10m long, meshed with 1 element, and
# there is no "x" displacement.  The mine is 300m deep
# and just the roof is studied (0<=z<=300).  The model sits
# between 0<=y<=450.  The excavation sits in 0<=y<=150.  This
# is a "half model": the boundary conditions are such that
# the model simulates an excavation sitting in -150<=y<=150
# inside a model of the region -450<=y<=450.  The
# excavation height is 3m (ie, the excavation lies within
# 0<=z<=3).  Mining is simulated by moving the excavation's
# roof down, until disp_z=-3 at t=1.
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions are:
#  - disp_x = 0 everywhere
#  - disp_y = 0 at y=0 and y=450
#  - disp_z = 0 for y>150
#  - disp_z = -3 at maximum, for 0<=y<=150.  See excav function.
# That is, rollers on the sides, free at top, and prescribed at bottom.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = -0.025*(300-z) MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa, varying down to 1 MPa when tensile strain = 1
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1

# PorousFlow simulation of injection and production in a simplified GeoTES aquifer
# Much of this file is standard porous-flow stuff.  The unusual aspects are:
# - transfer of the rates of changes of each species (kg.s) to the aquifer_geochemistry.i simulation.  This is achieved by saving these changes from the PorousFlowMassTimeDerivative residuals
# - transfer of the temperature field to the aquifer_geochemistry.i simulation
# Interesting behaviour can be simulated by this file without its 'parent' simulation, exchanger.i.  exchanger.i provides mass-fractions injected via the injection_rate_massfrac_* variables, but since these are more-or-less constant throughout the duration of the exchanger.i simulation, the initial_conditions specified below may be used.  Similar, exchanger.i provides injection_temperature, but that is also constant.
injection_rate = -0.02 # kg/s/m, negative because injection as a source
production_rate = 0.02 # kg/s/m, this is about the maximum that can be sustained by the aquifer, with its fairly low permeability, without porepressure becoming negative

# Beam bending.
# One end is clamped and the other end is subjected to a stress
# and micromechanical moment that will induce bending.
# The stress that will induce bending around the y axis is
# stress_xx = EAz
# This implies a micromechanical moment-stress of
# m_yx = (1/12)EAh^2 for joint_shear_stiffness=0.
# For joint_shear_stiffness!=0, the micromechanical moment-stress
# is
# m_yx = (1/12)EAa^2 G/(ak_s + G)
# All other stresses and moment stresses are assumed to be zero.
# With joint_shear_stiffness=0, and introducing D=-poisson*A, the
# nonzero strains are
# ep_xx = Az
# ep_yy = Dz
# ep_zz = Dz
# kappa_xy = -D
# kappa_yx = A
# This means the displacements are:
# u_x = Axz
# u_y = Dzy
# u_z = -(A/2)x^2 + (D/2)(z^2-y^2)
# wc_x = -Dy
# wc_y = Ax
# wc_z = 0
# This is bending of a bar around the y axis, in plane stress
# (stress_yy=0).  Displacements at the left-hand (x=0) are applied
# according to the above formulae; wc_x and wc_y are applied throughout
# the bar; and stress_xx is applied at the right-hand end (x=10).
# The displacements are measured and
# compared with the above formulae.
# The test uses: E=1.2, poisson=0.3, A=1.11E-2, h=2, ks=0.1, so
# stress_xx = 1.332E-2*z
# m_yx = 0.2379E-2

#theta_e = 10 degrees C; a = 252; E = 207000; nu = 0.3; alpha = 1.35e-5
#
#With uniform_refine = 3, KI converges to
#KI = 5.602461e+02 (interaction integral)
#KI = 5.655005e+02 (J-integral)
#
#Both are in good agreement with [Shih 1986]:
#average_value = 0.4857 = KI / (sigma_theta * sqrt(pi * a))
#sigma_theta = E * alpha * theta_e / (1 - nu)
# = 207000 * 1.35e-5 * 10 / (1 - 0.3) = 39.9214
#KI = average_value * sigma_theta * sqrt(pi * a) = 5.656e+02

# - 2D instead of 3D with different resolution.  Effectively this means a 1m height of RobPodgorney aquifer is simulated.  RobPodgorney total mass flux is 2.5kg/s meaning 0.25kg/s is appropriate here
# - Celsius instead of Kelvin
# - no use of PorousFlowPointEnthalpySourceFromPostprocessor since that is not yet merged into MOOSE: a DirichletBC is used instead
# - Use of PorousFlowFullySaturated instead of PorousFlowUnsaturated, and the save_component_rate_in feature to record the change in kg of each species at each node for passing to the Geochem simulation
# - MultiApps and Transfers to transfer information between this simulation and the aquifer_geochemistry.i simulation

# Demonstrates the correct usage of strain_at_nearest_qp when using a nodal PorousFlowPorosity
# For the PorousFlowPorosity Material to require the strain_at_nearest_qp=true flag, it must:
#  - be a nodal Material
#  - be coupled to solid mechanics (mechanical=true)
#  - be part of a simulation with DiracKernels
# The reason for this requirement is that the volumetric strain is a standard Material (at_nodes=false)
# so that it is evaluated at the single Dirac quadpoint, and has size = 1 (assuming just one Dirac point).
# However, the PorousFlowPorosity Material will have size = 2  (number of nodes in the element containing the Dirac point).
# So when the PorousFlowPorosity Material is evaluated, it will use _vol_strain at 2 points.
# If strain_at_nearest_qp=false, then _vol_strain will be evaluated at two quadpoints, but it only has size=1, leading to a segfault
# If strain_at_nearest_qp=true, then _vol_strain will be evaluated correctly just at the single quadpoint
#

# Large strain/large rotation cantilever beam test

# A 300 N point load is applied at the end of a 4 m long cantilever beam.
# Young's modulus (E) = 1e4
# Shear modulus (G) = 1e8
# shear coefficient (k) = 1.0
# Poisson's ratio (nu) = -0.99995
# Area (A) = 1.0
# Iy = Iz = 0.16

# The dimensionless parameter alpha = kAGL^2/EI = 1e6
# Since the value of alpha is quite high, the beam behaves like
# a thin beam where shear effects are not significant.

# Beam deflection:
# small strain+rot = 3.998 m (exact 4.0)
# large strain + small rotation = -0.05 m in x and 3.74 m in y
# large rotations + small strain = -0.92 m in x and 2.38 m in y
# large rotations + large strain = -0.954 m in x and 2.37 m in y (exact -1.0 m in x and 2.4 m in y)

# Mandel's problem of consolodation of a drained medium
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed.  The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width.  a = 1

# Test for small strain Euler beam bending in y direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# Beam is on the global YZ plane at a 45 deg. angle. The cross section geometry
# is non-symmetric

# Two phase density-driven convection of dissolved CO2 in brine
#
# The model starts with CO2 in the liquid phase only.  The CO2 diffuses into the brine.
# As the density of the CO2-saturated brine is greater
# than the unsaturated brine, a gravitational instability arises and density-driven
# convection of CO2-rich fingers descend into the unsaturated brine.
#
# The instability is seeded by a random perturbation to the porosity field.
# Mesh adaptivity is used to refine the mesh as the fingers form.
#
# Note: this model is computationally expensive, so should be run with multiple cores.

# Navier-Stokes (or Euler) flow of an ideal gas over a step.
#
# Note: this problem is not currently a regression test for the
# Navier-Stokes module since it is in some sense ill-posed.  As
# discussed in [0], the sharp corner of the step (both forward and
# backward-facing) introduces a singularity in the first derivative of
# the velocity and pressure fields, and therefore produces large
# numerical errors in the neighborhood of these points.  Physically,
# this numerical error can be interpreted as causing an artificial
# "boundary layer" to form just above the step, as well as a spurious
# production of entropy even though the flow remains subsonic.
# Nevertheless, the forward-facing step problem in particular remains
# a challenging and well-document test problem for flow solvers, and
# this input file is included to help facilitate its development and
# employment by users of the module.

# Mandel's problem of consolodation of a drained medium
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed.  The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width.  a = 1
# Soil height.  b = 0.1
# Soil's Lame lambda.  la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = G = 0.75
# Soil bulk modulus.  K = la + 2*mu/3 = 1
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance.  1/K = 1
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient.  B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Consolidation coefficient.  c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top.  F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here
#
# FINAL NOTE: The above solution assumes constant Biot Modulus.
# In porous_flow this is not true.  Therefore the solution is
# a little different than in the paper.  This test was therefore
# validated against MOOSE's poromechanics, which can choose either
# a constant Biot Modulus (which has been shown to agree with
# the analytic solution), or a non-constant Biot Modulus (which
# gives the same results as porous_flow).

# produces "mineral".  Using theta = 1 = eta, the DE that describes the prcipitation is
# reaction_rate = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is negative (ie precipitation) for a > 0.25
#
# a is held fixed at 0.5, so
# reaction_rate = - (1 - 2) = 1
#
# The mineral volume fraction evolves according to
# Mineral = mineral_old + dt * porosity_old * reaction_rate = mineral_old + dt * porosity_old
#
# Porosity evolves according to
# porosity = porosity(t=0) - (mineral - mineral(t=0))
#          = porosity(t=0) - (mineral_old + dt * porosity_old * reaction_rate - mineral(t=0))

# Euler flow of an ideal gas over a Gaussian "bump".
#
# The inlet is a stagnation pressure and temperature BC which
# corresponds to subsonic (M=0.5) flow with a static pressure of 1 atm
# and static temperature of 300K.  The outlet consists of a
# weakly-imposed static pressure BC of 1 atm.  The top and bottom
# walls of the channel weakly impose the "no normal flow" BC. The
# problem is initialized with freestream flow throughout the domain.
# Although this initial condition is less physically realistic, it
# helps the problem reach steady state more quickly.
#
# There is a sequence of uniformly-refined, geometry-fitted meshes
# from Yidong Xia available for solving this classical subsonic test
# problem (see the Mesh block below).  A coarse grid is used for the
# actual regression test, but changing one line in the Mesh block is
# sufficient to run this problem with different meshes.  An
# entropy-based error estimate is also provided, and can be used to
# demonstrate convergence of the numerical solution (since the true
# solution should produce zero entropy).  The error should converge at
# second-order in this norm.

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped masses at the ends of the beam.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass = 0.01899772 at the cantilever end
# mass = 2.0 at the fixed end (just for file testing purposes does not alter result)

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25

# This implies that the corresponding time period of this beam is 4s.

# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.

# The time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y                vel_y                accel_y
# 0.0    0.0                   0.0                  0.0

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# stress on a set of irregular hexes.  The mesh is composed of one
# block with seven elements.  The elements form a unit cube with one
# internal element.  There is a nodeset for each exterior node.
# The cube is displaced by 1e-6 units in x, 2e-6 in y, and 3e-6 in z.
# The faces are sheared as well (1e-6, 2e-6, and 3e-6 for xy, yz, and
# zx).  This gives a uniform strain/stress state for all six unique
# tensor components.
# With Young's modulus at 1e6 and Poisson's ratio at 0, the shear
# modulus is 5e5 (G=E/2/(1+nu)).  Therefore,
#
# stress xx = 1e6 * 1e-6 = 1
# stress yy = 1e6 * 2e-6 = 2
# stress zz = 1e6 * 3e-6 = 3
# stress xy = 2 * 5e5 * 1e-6 / 2 = 0.5
# (2 * G   * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 5e5 * 2e-6 / 2 = 1
# stress zx = 2 * 5e5 * 3e-6 / 2 = 1.5

# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material; however, in this case the stress free temperature of the material
# has been set to 200K so that there is an initial delta temperature of 100K.

# An initial temperature of 300K is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step.  The final temperature is 675K
# The thermal strain increment should therefore be
#     (675K - 300K) * 1.3e-5 1/K + 100K * 1.3e-5 1/K = 6.175e-3 m/m.

# This test uses a start up step to identify problems in the calculation of
# eigenstrains with a stress free temperature that is different from the initial
# value of the temperature in the problem

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable.  Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source, s, has units m^3/second/m^3.  Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)

# stress_zz = (bulk + 4*shear/3)*strain_zz   (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/second/m^3.  The ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)

# Expect
# disp_z = 0.3*10*s*t/((2 + 4*1.5/3) + 0.3^2*10) = 0.612245*s*t

# Dynamic problem with plasticity.
# A column of material (not subject to gravity) has the z-displacement
# of its sides fixed, but the centre of its bottom side is pushed
# upwards.  This causes failure in the bottom elements.
#
# The problem utilises damping in the following way.
# The DynamicStressDivergenceTensors forms the residual
# integral  grad(stress) + zeta*grad(stress-dot)
#     = V/L * elasticity * (du/dx + zeta * dv/dx)
# where V is the elemental volume, and L is the length-scale,
# and u is the displacement, and v is the velocity.
# The InertialForce forms the residual
# integral  density * (accel + eta * velocity)
#     = V * density * (a + eta * v)
# where a is the acceleration.
# So, a damped oscillator description with both these
# kernels looks like
# 0 = V * (density * a + density * eta * v + elasticity * zeta * v / L^2 + elasticity / L^2 * u)
# Critical damping is when the coefficient of v is
# 2 * sqrt(density * elasticity / L^2)
# In the case at hand, density=1E4, elasticity~1E10 (Young is 16GPa),
# L~1 to 10 (in the horizontal or vertical direction), so this coefficient ~ 1E7 to 1E6.
# Choosing eta = 1E3 and zeta = 1E-2 gives approximate critical damping.
# If zeta is high then steady-state is achieved very quickly.
#
# In the case of plasticity, the effective stiffness of the elements
# is significantly less.  Therefore, the above parameters give
# overdamping.
#
# This simulation is a nice example of the irreversable and non-uniqueness
# of simulations involving plasticity.  The result depends on the damping
# parameters and the time stepping.

# fully-saturated situation with a poly-line sink with use_mobility=true
# The poly-line consists of 2 points, and has a length
# of 0.5.  Each point is weighted with a weight of 0.1
# The PorousFlowPolyLineSink has
# p_or_t_vals = 0 1E7
# fluxes = 0 1
# so that for 0<=porepressure<=1E7
# base flux = porepressure * 1E-6 * mobility  (measured in kg.m^-1.s^-1),
# and when multiplied by the poly-line length, and
# the weighting of each point, the mass flux is
# flux = porepressure * 0.5*E-8 * mobility (kg.s^-1).
#
# The fluid and matrix properties are:
# porosity = 0.1
# element volume = 8 m^3
# density = dens0 * exp(P / bulk), with bulk = 2E7
# initial porepressure P0 = 1E7
# viscosity = 0.2
# So, fluid mass = 0.8 * density (kg)
#
# The equation to solve is
# d(Mass)/dt = - porepressure * 0.5*E-8 * density / viscosity
#
# PorousFlow discretises time to conserve mass, so to march
# forward in time, we must solve
# Mass(dt) = Mass(0) - P * 0.5E-8 * density / viscosity * dt
# or
# 0.8 * dens0 * exp(P/bulk) = 0.8 * dens0 * exp(P0/bulk) - P * 0.5E-8 * density / viscosity * dt
# For the numbers written above this gives
# P(t=1) = 6.36947 MPa
# which is given precisely by MOOSE

# Strata deformation and fluid flow aaround a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# The excavation takes 0.5 years.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
#  - no flow at x=0, z=-400 and z=0
#  - fixed porepressure at y=-1000, y=1000 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# A single-phase unsaturated fluid is used.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa, and time units are measured in years.
#
# The initial porepressure is hydrostatic with P=0 at z=0, so
# Porepressure ~ - 0.01*z MPa, where the fluid has density 1E3 kg/m^3 and
# gravity = = 10 m.s^-2 = 1E-5 MPa m^2/kg.
# To be more accurate, i use
# Porepressure = -bulk * log(1 + g*rho0*z/bulk)
# where bulk=2E3 MPa and rho0=1Ee kg/m^3.
# The initial stress is consistent with the weight force from undrained
# density 2500 kg/m^3, and fluid porepressure, and a Biot coefficient of 0.7, ie,
# stress_zz^effective = 0.025*z + 0.7 * initial_porepressure
# The maximum and minimum principal horizontal effective stresses are
# assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 2 MPa
# MC friction angle = 35 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1
# Fluid density at zero porepressure = 1E3 kg/m^3
# Fluid bulk modulus = 2E3 MPa
# Fluid viscosity = 1.1E-3 Pa.s = 1.1E-9 MPa.s = 3.5E-17 MPa.year

(modules/porous_flow/test/tests/energy_conservation/heat04_action.i)

# heat04, but using an action
#
# The sample is a single unit element, with fixed displacements on
# all sides.  A heat source of strength S (J/m^3/s) is applied into
# the element.  There is no fluid flow or heat flow.  The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5

# Pattern example 1

# Phase changes driven by a combination mechanical (elastic) and chemical
# driving forces. In this three phase system a matrix phase, an oversized and
# an undersized precipitate phase compete. The chemical free energy favors a
# phase separation into either precipitate phase. A mix of both precipitate
# emerges to balance lattice expansion and contraction.

# This example demonstrates the use of
# * ACMultiInterface
# * SwitchingFunctionConstraintEta and SwitchingFunctionConstraintLagrange
# * DerivativeParsedMaterial
# * ElasticEnergyMaterial
# * DerivativeMultiPhaseMaterial
# * MultiPhaseStressMaterial

# Terzaghi's problem of consolodation of a drained medium
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example.  Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height.  h = 10
# Soil's Lame lambda.  la = 2
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = 3
# Soil bulk modulus.  K = la + 2*mu/3 = 4
# Soil confined compressibility.  m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance.  1/K = 0.25
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus.  S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient.  c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top.  q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution).  p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution).  uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution).  uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

#
# This problem is modified from the Abaqus verification manual:
#   "1.5.4 Patch test for axisymmetric elements"
# The original stress solution is given as:
#   xx = yy = zz = 2000
#   xy = 400
#
# Here, E=1e6 and nu=0.25.
# However, with a +100 degree change in temperature and a coefficient
#   of thermal expansion of 1e-6, the solution becomes:
#   xx = yy = zz = 1800
#   xy = 400
#   since
#   E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800
#
# Also,
#
#   dSrr   dSrz   Srr-Stt
#   ---- + ---- + ------- + br = 0
#    dr     dz       r
#
# and
#
#   dSrz   Srz   dSzz
#   ---- + --- + ---- + bz = 0
#    dr     r     dz
#
# where
#   Srr = stress in rr
#   Szz = stress in zz
#   Stt = stress in theta-theta
#   Srz = stress in rz
#   br  = body force in r direction
#   bz  = body force in z direction
#
# This test is meant to exercise the Jacobian.  To that end, the body
# force has been turned off.  This makes the results differ slightly
# from the original values, but requires a correct Jacobian for minimal
# iterations.  Iteration plotting is turned on to ensure that the
# number of iterations needed does not increase.

# Strata deformation and fracturing around a coal mine
#
# A 2D geometry is used that simulates a transverse section of
# the coal mine.  The model is actually 3D, but the "x"
# dimension is only 10m long, meshed with 1 element, and
# there is no "x" displacement.  The mine is 400m deep
# and just the roof is studied (0<=z<=400).  The model sits
# between 0<=y<=450.  The excavation sits in 0<=y<=150.  This
# is a "half model": the boundary conditions are such that
# the model simulates an excavation sitting in -150<=y<=150
# inside a model of the region -450<=y<=450.  The
# excavation height is 3m (ie, the excavation lies within
# 0<=z<=3).
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this elastic simulation are:
#  - disp_x = 0 everywhere
#  - disp_y = 0 at y=0 and y=450
#  - disp_z = 0 for y>150
#  - wc_x = 0 at y=0 and y=450.
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = -0.025*(300-z) MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# This is an elastic simulation, but the weak-plane and Drucker-Prager
# parameters and AuxVariables may be found below.  They are irrelevant
# in this simulation.  The weak-plane and Drucker-Prager cohesions,
# tensile strengths and compressive strengths have been set very high
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa

# Large strain/large rotation cantilever beam tese

# A 300 N point load is applied at the end of a 4 m long cantilever beam.
# Young's modulus (E) = 1e4
# Shear modulus (G) = 1e8
# shear coefficient (k) = 1.0
# Area (A) = 1.0
# Iy = Iz = 0.16

# The non-dimensionless parameter alpha = kAGL^2/EI = 1e6
# Since the value of alpha is quite high, the beam behaves like
# a thin beam where shear effects are not significant.

# Beam deflection:
# small strain+rot = 3.998 m (exact 4.0)
# large strain + small rotation = -0.05 m in x and 3.74 m in y
# large rotations + small strain = -0.92 m in x and 2.38 m in y
# large rotations + large strain = -0.954 m in x and 2.37 m in y (exact -1.0 m in x and 2.4 m in y)

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The theoretical first frequency of this beam is:
# f1 = 1/(2 pi) * sqrt(3EI/(mL^3)) = 0.25

# This implies that the corresponding time period of this beam is 4s.

# The FEM solution for this beam with 10 element gives time periods of 4s with time step of 0.01s.
# A higher time step of 0.1 s is used in the test to reduce computational time.

# The time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y                vel_y                accel_y
# 0.0    0.0                   0.0                  0.0

# Terzaghi's problem of consolodation of a drained medium
# The FullySaturated Kernels are used, with multiply_by_density = false
# so that this becomes a linear problem with constant Biot Modulus
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example.  Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height.  h = 10
# Soil's Lame lambda.  la = 2
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = 3
# Soil bulk modulus.  K = la + 2*mu/3 = 4
# Soil confined compressibility.  m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance.  1/K = 0.25
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus.  S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient.  c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top.  q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution).  p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution).  uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution).  uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

# Using a BasicTHM action
# Terzaghi's problem of consolodation of a drained medium
# The FullySaturated Kernels are used, with multiply_by_density = false
# so that this becomes a linear problem with constant Biot Modulus
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example.  Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height.  h = 10
# Soil's Lame lambda.  la = 2
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = 3
# Soil bulk modulus.  K = la + 2*mu/3 = 4
# Soil confined compressibility.  m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance.  1/K = 0.25
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus.  S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient.  c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top.  q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution).  p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution).  uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution).  uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

# This simulation models the mechanics solution for a solid sphere under
# pressure, applied on the outer surfaces, using 1D spherical symmetry
# assumpitions.  The inner center of the sphere, r = 0, is pinned to prevent

#
# From Bower (Applied Mechanics of Solids, 2008, available online at
# solidmechanics.org/text/Chapter4_1/Chapter4_1.htm), and applying the outer
# pressure and pinned displacement boundary conditions set in this simulation,
# the radial displacement is given by:
#
# u(r) = \frac{- P * (1 - 2 * v) * r}{E}
#
# where P is the applied pressure, v is Poisson's ration, E is Young's Modulus,
# and r is the radial position.
#
# The test assumes a radius of 4, zero displacement at r = 0mm, and an applied

# taken from an earlier beam regression test for static loading. The maximum
# applied load of 50000 lb should result in a displacement of 3.537e-3. Since
# the constraint is frictional with a low normal force (1.0) and coefficient
# of friction (0.05) and the short beam is much less stiff, the

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# Beam is on the XY plane and the loading is in-plane, perpendicular to the
# beam longitudinal axis.

# Checking the Jacobian of Flux-Limited TVD Advection, using flux_limiter_type = vanleer
#
# The initial conditions are u=x.  This means that the argument of the flux limiter is 1, so that
# the flux_limiter=1 everywhere, irrespective of flux_limiter_type (except for 'none').  However
# superbee and minmod are nondifferentiable at this point, so using those flux_limiter_type will
# result in a poor Jacobian
#
# Here we use snes_check_jacobian instead of snes_type=test.  The former just checks the Jacobian for the
# random initial conditions, while the latter checks for u=1 and u=-1
#
# The Jacobian is correct for u=1 and u=-1, but the finite-difference scheme used by snes_type=test gives the
# wrong answer.
# For u=1, the Kuzmin-Turek scheme adds as much antidiffusion as possible, resulting in a central-difference
# version of advection (flux_limiter = 1).  This is correct, and the Jacobian is calculated correctly.
# However, when computing the Jacobian using finite differences, u is increased or decreased at a node.
# This results in that node being at a maximum or minimum, which means no antidiffusion should be added
# (flux_limiter = 0).  This corresponds to a full-upwind scheme.  So the finite-difference computes the
# Jacobian in the full-upwind scenario, which is incorrect (the original residual = 0, after finite-differencing
# the residual comes from the full-upwind scenario).

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# Beam is on the global YZ plane, at 45 deg. angle; with in-plane loading
# perpendicular to the beam axis. Cross section moment of inertia about
# local z axis has been decreased 3 times to test for correct local section
# orientation.

# Test that models bending of a rotated cantilever beam using shell elements

# A cantilever beam of length 10 m (in Z direction) and cross-section
# 1 m x 0.1 m is modeled using 4 shell elements placed along the length
# (Figure 6a from Dvorkin and Bathe, 1984). All displacements and
# X rotations are fixed on the bottom boundary. E = 2100000 and v = 0.0.
# A load of 0.5 N (in the Y direction) is applied at each node on the top
# boundary resulting in a total load of 1 N.

# The analytical solution for displacement at tip using small strain/rotations # is PL^3/3EI + PL/AG = 1.90485714 m
# The FEM solution using 4 shell elements is 1.875095 m with a relative error
# of 1.5%.

# Similarly, the analytical solution for slope at tip is PL^2/2EI = 0.285714286
# The FEM solution is 0.2857143 and the relative error is 5e-6%.

# The stress_zz for the four elements at y = -0.57735 * (t/2) (first qp below mid-surface of shell) are:
# 3031.089 Pa, 2165.064 Pa, 1299.038 Pa and 433.0127 Pa.
# Note the above values are the average stresses in each element.

# Analytically, stress_zz decreases linearly from z = 0 to z = 10 m.
# The maximum value of stress_zz at z = 0 is My/I = PL * 0.57735*(t/2)/I = 3464.1 Pa
# Therefore, the analytical value of stress at y = -0.57735 * (t/2) at the mid-point
# of the four elements are:
# 3031.0875 Pa, 2165.0625 Pa, 1299.0375 Pa ,433.0125 Pa

# The relative error in stress_zz is in the order of 5e-5%.

# The stress_yz at y = -0.57735 * (t/2) at all four elements from the simulation is 10 Pa.
# The analytical solution for the shear stress is: V/2/I *((t^2)/4 - y^2), where the shear force (V)
# is 1 N at any z along the length of the beam. Therefore, the analytical shear stress at
# y = -0.57735 * (t/2) is 10 Pa at any location along the length of the beam.

#
# Truss in two dimensional space
#
# The truss is made of five equilateral triangles supported at each end.
# The truss starts at (0,0).  At (1,0), there is a point load of 25.
# The reactions are therefore
#  Ryleft  = 2/3 * 25 = 16.7
#  Ryright = 1/3 * 25 = 8.33
# The area of each member is 0.8.
# Statics gives the stress in each member.  For example, for element 6 (from
#   (0,0) to (1/2,sqrt(3)/2)), the force is
#   f = 2/3 * 25 * 2/sqrt(3) = 100/3/sqrt(3) (compressive)
#   and the stress is
#   s = -100/3/sqrt(3)/0.8 = -24.06

# An undrained oedometer test on a saturated poroelastic sample.
#
# The sample is a single unit element, with roller BCs on the sides
# and bottom.  A constant displacement is applied to the top: disp_z = -0.01*t.
# There is no fluid flow.
#
# Under these conditions
# porepressure = -(Fluid bulk modulus)*log(1 - 0.01t)
# stress_xx = (bulk - 2*shear/3)*disp_z/L (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*disp_z/L (remember this is effective stress)
# where L is the height of the sample (L=1 in this test)
#
# Parameters:
# Bulk modulus = 2
# Shear modulus = 1.5
# fluid bulk modulus = 1
#
# Desired output:
# zdisp = -0.01*t
# p0 = 1*log(1-0.01t)
# stress_xx = stress_yy = -0.01*t
# stress_zz = -0.04*t

# taken from an earlier beam regression test for static loading. The maximum
# applied load of 50000 lb should result in a displacement of 3.537e-3. Since

# Using a two-phase system (see dissolution_limited.i for the single-phase)
# The saturation and porosity are chosen so that the results are identical to dissolution_limited.i
#
# The dissolution reaction, with limited initial mineral concentration
#
# a <==> mineral
#
# produces "mineral".  Using mineral_density = fluid_density, theta = 1 = eta, the DE is
#
# a' = -(mineral / (porosity * saturation))' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is positive for a < 0.25, ie dissolution for a(t=0) < 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
#   = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity * saturation
#
# However, c(t=0) is small, so that the reaction only works until c=0, then a and c both remain fixed
#
# This test checks that (a + c / (porosity * saturation)) is time-independent, and that a follows the above solution, until c=0 and thereafter remains fixed.
#
# Aside:
#    The exponential curve is not followed exactly because moose actually solves
#    (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#    which does not give an exponential exactly, except in the limit dt->0

# Mandel's problem of consolodation of a drained medium
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed.  The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width.  a = 1
# Soil height.  b = 0.1
# Soil's Lame lambda.  la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = G = 0.75
# Soil bulk modulus.  K = la + 2*mu/3 = 1
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance.  1/K = 1
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient.  B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Consolidation coefficient.  c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top.  F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.
# The solution involves complicated infinite series, so I shall not write it here

# apply a basic sink fluxes to all boundaries.
# Sink strength = S kg.m^-2.s^-1
#
# Use fully-saturated physics, with no flow
# (permeability is zero).
# Each finite element is (2m)^3 in size, and
# porosity is 0.125, so each element holds 1 m^3
# of fluid.
# With density = 10 exp(pp)
# then each element holds 10 exp(pp) kg of fluid
#
# Each boundary node that is away from other boundaries
# (ie, not on a mesh corner or edge) therefore holds
# 5 exp(pp)
# kg of fluid, which is just density * porosity * volume_of_node
#
# Each of such nodes are exposed to a sink flux of strength
# S * A
# where A is the area controlled by the node (in this case 4 m^2)
#
# So d(5 exp(pp))/dt = -4S, ie
# exp(pp) = exp(pp0) - 0.8 * S * t
#
# This is therefore similar to s01.i .  However, this test is
# run 6 times: one for each boundary.  The purpose of this is
# to ensure that the PorousFlowSink BC removes fluid from the
# correct nodes.  This is nontrivial because of the upwinding
# and storing of Material Properties at nodes.

# Uses an Abbo et al smoothed version of Mohr-Coulomb (via SolidMechanicsPlasticMohrCoulomb and ComputeMultiPlasticityStress) to simulate the following problem.
# A cubical block is notched around its equator.
# All of its outer surfaces have roller BCs, but the notched region is free to move as needed
# The block is initialised with a high hydrostatic tensile stress
# Without the notch, the BCs do not allow contraction of the block, and this stress configuration is admissible
# With the notch, however, the interior parts of the block are free to move in order to relieve stress, and this causes plastic failure
# The top surface is then pulled upwards (the bottom is fixed because of the roller BCs)
# This causes more failure

# Checking that gravity head is established

# fully saturated with fully-saturated Kernel
# For better agreement with the analytical solution (ana_pp), just increase nx
# NOTE: the numerics described by this input file is quite delicate.  Firstly, the steady-state solution does not depend on the mass-fraction distribution, so the mass-fraction variable can assume any values (with the constraint that its integral is the same as the initial condition).  Secondly, because the PorousFlowFullySaturatedDarcyFlow does no upwinding, the steady-state porepressure distribution can contain non-physical oscillations.  The solver choice and mesh choice used below mean the result is as expected, but changing these can produce different results.

# The sample is a single unit element, with roller BCs on the sides
# and bottom.  A constant displacement is applied to the top: disp_z = -0.01*t.
# There is no fluid flow or heat flow.
# Heat energy conservation is checked.
#
# Under these conditions (here L is the height of the sample: L=1 in this case):
# porepressure = porepressure(t=0) - (Fluid bulk modulus)*log(1 - 0.01*t)
# stress_xx = (bulk - 2*shear/3)*disp_z/L (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*disp_z/L (remember this is effective stress)
# Also, the total heat energy must be conserved: this is
# fluid_mass * fluid_heat_cap * temperature + (1 - porosity) * rock_density * rock_heat_cap * temperature * volume
# Since fluid_mass is conserved, and volume = (1 - 0.01*t), this can be solved for temperature:
# temperature = initial_heat_energy / (fluid_mass * fluid_heat_cap + (1 - porosity) * rock_density * rock_heat_cap * (1 - 0.01*t))
#
# Parameters:
# Bulk modulus = 2
# Shear modulus = 1.5
# fluid bulk modulus = 0.5
# initial porepressure = 0.1
# initial temperature = 10
#
# Desired output:
# zdisp = -0.01*t
# p0 = 0.1 - 0.5*log(1-0.01*t)
# stress_xx = stress_yy = -0.01*t
# stress_zz = -0.04*t
# t0 =  11.5 / (0.159 + 0.99 * (1 - 0.01*t))
#
# Regarding the "log" - it comes from preserving fluid mass
#
# Note that the PorousFlowMassVolumetricExpansion and PorousFlowHeatVolumetricExpansion Kernels are used

# In this example, two primary species a and b are transported by diffusion and convection
# from the left of the porous medium, reacting to form two equilibrium species pa2 and pab
# according to the equilibrium reaction specified in the AqueousEquilibriumReactions block as:
#
#      reactions = '2a = pa2     2
#                   a + b = pab -2'
#
# where the 2 is the weight of the equilibrium species, the 2 on the RHS of the first reaction
# refers to the equilibrium constant (log10(Keq) = 2), and the -2 on the RHS of the second
# reaction equates to log10(Keq) = -2.
#
# This example is identical to 2species.i, except that it explicitly includes all AuxKernels
# and Kernels that are set up by the action in 2species.i, and that the equilbrium constants
# are provided by AuxVariables

# A sample is constrained on all sides, except its top
# and its boundaries are
# also impermeable.  Fluid is pumped into the sample via a
# volumetric source (ie kg/second per cubic meter), and the
# rise in the top surface, porepressure, and stress are observed.
#
# In the standard poromechanics scenario, the Biot Modulus is held
# fixed and the source has units 1/time.  Then the expected result
# is
# strain_zz = disp_z = BiotCoefficient*BiotModulus*s*t/((bulk + 4*shear/3) + BiotCoefficient^2*BiotModulus)
# porepressure = BiotModulus*(s*t - BiotCoefficient*strain_zz)
# stress_xx = (bulk - 2*shear/3)*strain_zz   (remember this is effective stress)
# stress_zz = (bulk + 4*shear/3)*strain_zz   (remember this is effective stress)
#
# In porous_flow, however, the source has units kg/s/m^3 and the
# Biot Modulus is not held fixed.  This means that disp_z, porepressure,
# etc are not linear functions of t.  Nevertheless, the ratios remain
# fixed:
# stress_xx/strain_zz = (bulk - 2*shear/3) = 1 (for the parameters used here)
# stress_zz/strain_zz = (bulk + 4*shear/3) = 4 (for the parameters used here)
# porepressure/strain_zz = 13.3333333 (for the parameters used here)

# Test for small strain Euler beam bending in z direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poisson's ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 5.78e-2 m

# Using 10 elements to discretize the beam element, the FEM solution is 5.766e-2 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# References:
# Prathap and Bhashyam (1982), International journal for numerical methods in engineering, vol. 18, 195-210.
# Note that the force is scaled by 1e-4 compared to the reference problem.

# Applying the following deformation to the zmax surface of a unit cube:
# disp_x = 32*t/Gt
# disp_y = 24*t/Gt
# disp_z = 10*t/E_2222
# but leaving wc_x and wc_y unfixed
# yields the following strains:
# strain_xz = 32*t/Gt - wc_y = 9.6*t - wc_y
# strain_zx = wc_y
# strain_yz = 24*t/Gt + wc_x = 7.2*t + wc_x
# strain_zy = - wc_x
# strain_zz = 10*t/E_2222 = 1.23333333*t
# and all other components, and the curvature, are zero (assuming
# wc is uniform over the cube).
#
# When wc=0, the nonzero components of stress are therefore:
# stress_xx = stress_yy = 3.33333*t
# stress_xz = stress_zx = 32*t
# stress_yz = stress_zy = 24*t
# stress_zz = 10*t
# The moment stress is zero.
# So q = 40*t and p = 10*t
#
# Use tan(friction_angle) = 0.5 and tan(dilation_angle) = E_qq/Epp/2, and cohesion=20,
# the system should return to p=0, q=20, ie stress_zz=0, stress_xz=16,
# stress_yz=12 on the first time step (t=1)
# and
# stress_xx = stress_yy = 0
# and
# stress_zx = 32, and stress_zy = 24.
# This has resulted in a non-symmetric stress tensor, and there is
# zero moment stress, so the system is not in equilibrium.  A
# nonzero wc must therefore be generated.
#
# The obvious choice of wc is such that stress_zx = 16 and
# stress_zy = 12, because then the final returned stress will
# be symmetric.  This gives
# wc_y = - 48
# wc_x = 36
# At t=1, the nonzero components of stress are
# stress_xx = stress_yy = 3.33333
# stress_xz = 32, stress_zx = 16
# stress_yz = 24, stress_zy = 12
# stress_zz = 10*t
# The moment stress is zero.
#
# The returned stress is
# stress_xx = stress_yy = 0
# stress_xz = stress_zx = 16
# stress_yz = stress_zy = 12
# stress_zz = 0
# The total strains are given above.
# Since q returned from 40 to 20, plastic_strain_xz = 9.6/2 = 4.8
# and plastic_strain_yz = 7.2/2 = 3.6.
# Since p returned to zero, all of the total strain_zz is
# plastic, ie plastic_strain_zz = 1.23333

#
# Truss in two dimensional space
#
# The truss is made of five equilateral triangles supported at each end.
# The truss starts at (0,0).  At (1,0), there is a point load of 25.
# The reactions are therefore
#  Ryleft  = 2/3 * 25 = 16.7
#  Ryright = 1/3 * 25 = 8.33
# The area of each member is 0.8.
# Statics gives the stress in each member.  For example, for element 6 (from
#   (0,0) to (1/2,sqrt(3)/2)), the force is
#   f = 2/3 * 25 * 2/sqrt(3) = 100/3/sqrt(3) (compressive)
#   and the stress is
#   s = -100/3/sqrt(3)/0.8 = -24.06

# Test for simply supported plate under uniform pressure

# One quarter of a 50 m x 50 m x 1m plate is modeled in this test.
# Pressure loading is applied on the top surface using nodal forces
# of magnitude -10 N on all nodes. This corresponds to a pressure (q) of
# -10.816 N/m^2.

# The FEM solution at (0,0), which is at the center of the full plate
# is -2.997084e-03 m.

# The analytical solution for displacement at center of plate obtained
# using a thin plate assumption for a square plate is
# w = 16 q a^4/(D*pi^6) \sum_{m = 1,3,5, ..}^\inf \sum_{n = 1,3,5, ..}^\inf  (-1)^{(m+n-2)/2}/(mn*(m^2+n^2)^2)

# The above solution is the Navier's series solution from the "Theory of plates
# and shells" by Timoshenko and Woinowsky-Krieger (1959).

# where a = 50 m, q = -10.816 N/m^2 and D = E/(12(1-v^2))
# The analytical series solution converges to 2.998535904e-03 m
# when the first 16 terms of the series are considered (i.e., until
# m & n = 7).

# The resulting relative error between FEM and analytical solution is
# 0.048%.

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The beam is massless with a lumped mass at the end of the beam. The lumped
# mass also has a moment of inertia associated with it.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# mass (m) = 0.01899772
# Moment of inertia of lumped mass:
# Ixx = 0.2
# Iyy = 0.1
# Izz = 0.1
# mass proportional damping coefficient (eta) = 0.1

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The displacement time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time   disp_y              vel_y               accel_y
# 0.0    0.0                 0.0                 0.0

# Strata deformation and fracturing around a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young's modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = 0.025*z MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1

# The precipitation reaction
#
# a <==> mineral
#
# produces "mineral".  Using mineral_density = fluid_density, theta = 1 = eta, the DE is
#
# a' = -(mineral / porosity)' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is negative for a > 0.25, ie precipitation for a(t=0) > 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
#   = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity
#
# This test checks that (a + c / porosity) is time-independent, and that a follows the above solution
#
# Aside:
#    The exponential curve is not followed exactly because moose actually solves
#    (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#    which does not give an exponential exactly, except in the limit dt->0

# Strata deformation and fluid flow aaround a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# The excavation takes 0.5 years.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
#  - no flow at x=0, z=-400 and z=0
#  - fixed porepressure at y=-1000, y=1000 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# A single-phase unsaturated fluid is used.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa, and time units are measured in years.
#
# The initial porepressure is hydrostatic with P=0 at z=0, so
# Porepressure ~ - 0.01*z MPa, where the fluid has density 1E3 kg/m^3 and
# gravity = = 10 m.s^-2 = 1E-5 MPa m^2/kg.
# To be more accurate, i use
# Porepressure = -bulk * log(1 + g*rho0*z/bulk)

# Strata deformation and fracturing around a coal mine
#
# A 2D geometry is used that simulates a transverse section of
# the coal mine.  The model is actually 3D, but the "x"
# dimension is only 10m long, meshed with 1 element, and
# there is no "x" displacement.  The mine is 400m deep
# and just the roof is studied (0<=z<=400).  The model sits
# between 0<=y<=450.  The excavation sits in 0<=y<=150.  This
# is a "half model": the boundary conditions are such that
# the model simulates an excavation sitting in -150<=y<=150
# inside a model of the region -450<=y<=450.  The
# excavation height is 3m (ie, the excavation lies within
# 0<=z<=3).
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this elastic simulation are:
#  - disp_x = 0 everywhere
#  - disp_y = 0 at y=0 and y=450
#  - disp_z = 0 at z=0, but there is a time-dependent
#               Young's modulus that simulates excavation
#  - wc_x = 0 at y=0 and y=450.
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = -0.025*(300-z) MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa, varying down to 1 MPa when tensile strain = 1
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1

# Test for damped small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# mass proportional rayleigh damping(eta) = 0.1
# stiffness proportional rayleigh damping(eta) = 0.1
# HHT time integration parameter (alpha) = -0.3
# Corresponding Newmark beta time integration parameters beta = 0.4225 and gamma = 0.8

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the behaves like a Euler-Bernoulli beam.

# The displacement time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time  disp_y                vel_y                accel_y

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# The beam centerline is positioned on the global XZ plane at a 45deg. angle.
# Loading is along on the XZ plane perpendicular to beam centerline.

# Testing StickyBC
#
# Push the top of an element downward until the bottom hits an (invisible) obstruction.
# 10 timesteps are used.  In each timestep disp_y is decreased by 0.1.  The
# StickyBC has a min_value of -0.49, so at timestep 5 this bound will be violated
# and the bottom boundary will be fixed forever after.
#
# This test also illustrates that StickyBC is only ever meant to be used in
# special situations:
# - if, after the simulation ends, the top is moved upward again, the StickyBC
#   will keep the bottom fixed.  Ie, the StickyBC is truly "sticky".
# - setting min_value = -0.5 in this test illustrates the "approximate" nature
#   of StickyBC, in that some nodes will be fixed at disp_y=-0.5, while others
#   will be fixed at disp_y=-0.6, due to the timestepping and roundoff errors
#   in MOOSE's solution.

# Test that models bending of a cantilever beam using shell elements

# A cantilever beam of length 10 m (in Y direction) and cross-section
# 1 m x 0.1 m is modeled using 4 shell elements placed along the length
# (Figure 6a from Dvorkin and Bathe, 1984). All displacements and
# X rotations are fixed on the bottom boundary. E = 2100000 and v = 0.0.
# A load of 0.5 N (in the Z direction) is applied at each node on the top
# boundary resulting in a total load of 1 N.

# The analytical solution for displacement at tip using small strain/rotations # is PL^3/3EI + PL/AG = 1.90485714 m
# The FEM solution using 4 shell elements is 1.875095 m with a relative error
# of 1.5%.

# Similarly, the analytical solution for slope at tip is PL^2/2EI = 0.285714286
# The FEM solution is 0.2857143 and the relative error is 5e-6%.

# The stress_yy for the four elements at z = -0.57735 * (t/2) (first qp below mid-surface of shell) are:
# 3031.089 Pa, 2165.064 Pa, 1299.038 Pa and 433.0127 Pa.
# Note the above values are the average stresses in each element.

# Analytically, stress_yy decreases linearly from y = 0 to y = 10 m.
# The maximum value of stress_yy at y = 0 is Mz/I = PL * 0.57735*(t/2)/I = 3464.1 Pa
# Therefore, the analytical value of stress at z = -0.57735 * (t/2) at the mid-point
# of the four elements are:
# 3031.0875 Pa, 2165.0625 Pa, 1299.0375 Pa ,433.0125 Pa

# The relative error in stress_yy is in the order of 5e-5%.

# The stress_yz at z = -0.57735 * (t/2) at all four elements from the simulation is 10 Pa.
# The analytical solution for the shear stress is: V/2/I *((t^2)/4 - z^2), where the shear force (V)
# is 1 N at any y along the length of the beam. Therefore, the analytical shear stress at
# z = -0.57735 * (t/2) is 10 Pa at any location along the length of the beam.

# Terzaghi's problem of consolodation of a drained medium
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example.  Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height.  h = 10
# Soil's Lame lambda.  la = 2
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = 3
# Soil bulk modulus.  K = la + 2*mu/3 = 4
# Soil confined compressibility.  m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance.  1/K = 0.25
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus.  S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient.  c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top.  q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution).  p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution).  uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution).  uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
#
# FINAL NOTE: The above solution assumes constant Biot Modulus.
# In porous_flow this is not true.  Therefore the solution is
# a little different than in the paper.  This test was therefore
# validated against MOOSE's poromechanics, which can choose either
# a constant Biot Modulus (which has been shown to agree with
# the analytic solution), or a non-constant Biot Modulus (which
# gives the same results as porous_flow).

# Liquid and gas properties for code intercomparison problem 3
#
# From Pruess et al, Code intercomparison builds confidence in
# numerical simulation models for geologic disposal of CO2, Energy 29 (2004)
#
# This test simply calculates density and viscosity of each phase for
# various pressures and salinities, as well as mass fractions of CO2 in the
# liquid phase and H2O in the gas phase.
#
# Four versions of this are run:
# 1) No CO2, 0 salt mass fraction (pure water)
# 2) Enough CO2 to form gas phase, 0 salt mass fraction (pure water)
# 3) No CO2, 0.15 salt mass fraction
# 4) Enough CO2 to form gas phase, 0.15 salt mass fraction
#
# These results compare well with detailed results presented in Pruess et al,
# Intercomparison of numerical simulation codes for geologic disposal of CO2,
# LBNL-51813 (2002)

# This example uses plasticity, but with inifinitely large yield strength, so it is really elasticity
#
# Analytically, the displacements are
# wc_z = B sinh(w_e y)
# disp_x = (2 mu_c B / w_e / (mu + mu_c)) (1 - cosh(w_e y))
# with w_e^2 = 2 mu mu_c / be / (mu + mu_c)
# and B = arbitrary integration constant
#
# Also, the only nonzero stresses are
# m_zy = 2 B be w_e cosh(w_e y)
# si_yx = -4 mu mu_c/(mu + mu_c) B sinh(w_e y)
#
# MOOSE gives these stress components correctly.
# However, it also gives a seemingly non-zero si_xy
# component.  Upon increasing the resolution of the
# mesh (ny=10000, for example), the stress components
# are seen to limit correctly to the above forumlae
#
# I use mu = 2, mu_c = 3, be = 0.6, so w_e = 2
# Also i use B = 1, so at y = 1

# Test for small strain timoshenko beam bending in z direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.00027846257
# Poisson's ratio (nu) = 0.3
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 204.3734

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = 5.868e-2m

# Using 10 elements to discretize the beam element, the FEM solution is 5.852e-2 m.
# This deflection matches the FEM solution given in Prathap and Bhashyam (1982).

# References:
# Prathap and Bhashyam (1982), International journal for numerical methods in engineering, vol. 18, 195-210.
# Note that the force is scaled by 1e-4 compared to the reference problem.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 2D axisymmetric geometry.
# This test uses the strain calculator ComputeAxisymmetricRZFiniteStrain,
# which is generated through the use of the SolidMechanics QuasiStatic Physics.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
#   where:
#          Pi = inner pressure
#          Po = outer pressure
#          ri = inner radius
#          ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000 at t = 1.0, respectively. The resulting compressive
# tangential stress is largest at the inner wall and, from the above equation, has a
# value of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

# Terzaghi's problem of consolodation of a drained medium
#
# A saturated soil sample sits in a bath of water.
# It is constrained on its sides, and bottom.
# Its sides and bottom are also impermeable.
# Initially it is unstressed.
# A normal stress, q, is applied to the soil's top.
# The soil then slowly compresses as water is squeezed
# out from the sample from its top (the top BC for
# the porepressure is porepressure = 0).
#
# See, for example.  Section 2.2 of the online manuscript
# Arnold Verruijt "Theory and Problems of Poroelasticity" Delft University of Technology 2013
# but note that the "sigma" in that paper is the negative
# of the stress in TensorMechanics
#
# Here are the problem's parameters, and their values:
# Soil height.  h = 10
# Soil's Lame lambda.  la = 2
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = 3
# Soil bulk modulus.  K = la + 2*mu/3 = 4
# Soil confined compressibility.  m = 1/(K + 4mu/3) = 0.125
# Soil bulk compliance.  1/K = 0.25
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Soil initial storativity, which is the reciprocal of the initial Biot modulus.  S = phi0/Kf + (alpha - phi0)(1 - alpha)/K = 0.0625
# Consolidation coefficient.  c = k/(S + alpha^2 m) = 13.95348837
# Normal stress on top.  q = 1
# Initial porepressure, resulting from instantaneous application of q, assuming corresponding instantaneous increase of porepressure (Note that this is calculated by MOOSE: we only need it for the analytical solution).  p0 = alpha*m*q/(S + alpha^2 m) = 0.69767442
# Initial vertical displacement (down is positive), resulting from instantaneous application of q (Note this is calculated by MOOSE: we only need it for the analytical solution).  uz0 = q*m*h*S/(S + alpha^2 m)
# Final vertical displacement (down in positive) (Note this is calculated by MOOSE: we only need it for the analytical solution).  uzinf = q*m*h
#
# The solution for porepressure is
# P = 4*p0/\pi \sum_{k=1}^{\infty} \frac{(-1)^{k-1}}{2k-1} \cos ((2k-1)\pi z/(2h)) \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))
# This series converges very slowly for ct/h^2 small, so in that domain
# P = p0 erf( (1-(z/h))/(2 \sqrt(ct/h^2)) )
#
# The degree of consolidation is defined as
# U = (uz - uz0)/(uzinf - uz0)
# where uz0 and uzinf are defined above, and
# uz = the vertical displacement of the top (down is positive)
# U = 1 - (8/\pi^2)\sum_{k=1}^{\infty} \frac{1}{(2k-1)^2} \exp(-(2k-1)^2 \pi^2 ct/(4 h^2))

# Test for damped small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0
# mass proportional rayleigh damping(eta) = 0.1
# stiffness proportional rayleigh damping(eta) = 0.1
# HHT time integration parameter (alpha) = -0.3
# Corresponding Newmark beta time integration parameters beta = 0.4225 and gamma = 0.8

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the behaves like a Euler-Bernoulli beam.

# The displacement time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time  disp_y                vel_y                accel_y

# Test for small strain timoshenko beam bending in y direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.00027846257
# Poisson's ratio (nu) = 0.3
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 204.3734

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = 5.868e-4 m

# Using 10 elements to discretize the beam element, the FEM solution is 5.852e-2m.
# This deflection matches the FEM solution given in Prathap and Bhashyam (1982).

# References:
# Prathap and Bhashyam (1982), International journal for numerical methods in engineering, vol. 18, 195-210.
# Note that the force is scaled by 1e-4 compared to the reference problem.

# Test for small strain Euler beam bending in y direction

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# Steady-state test for the ThermoDiffusion kernel.
#
# This test applies a constant temperature gradient to drive thermo-diffusion
# in the variable u. At steady state, the thermo-diffusion is balanced by
# diffusion due to Fick's Law, so the total flux is
#
#   J = -D ( grad(u) - ( Qstar u / R ) grad(1/T) )
#
# If there are no fluxes at the boundaries, then there is no background flux and
# these two terms must balance each other everywhere:
#
#   grad(u) = ( Qstar u / R ) grad(1/T)
#
# The dx can be eliminated to give
#
#   d(ln u) / d(1/T) = Qstar / R
#
# This can be solved to give the profile for u as a function of temperature:
#
#   u = A exp( Qstar / R T )
#
# Here, we are using simple heat conduction with Dirichlet boundaries on 0 <= x <= 1
# to give a linear profile for temperature: T = x + 1. We also need to apply one
# boundary condition on u, which is u(x=0) = 1. These conditions give:
#
#   u = exp( -(Qstar/R) (x/(x+1)) )
#
# This analytical result is tracked by the aux variable "correct_u".

# Test for small strain euler beam vibration in y direction

# An impulse load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 1e4
# Shear modulus (G) = 4e7
# Shear coefficient (k) = 1.0
# Cross-section area (A) = 0.01
# Iy = 1e-4 = Iz
# Length (L)= 4 m
# density (rho) = 1.0

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 6.4e6
# Therefore, the beam behaves like a Euler-Bernoulli beam.

# The theoretical first and third frequencies of this beam are:
# f1 = 1/(2 pi) * (3.5156/L^2) * sqrt(EI/rho)
# f2 = 6.268 f1

# This implies that the corresponding time period of this beam are 2.858 s and 0.455s

# The FEM solution for this beam with 10 element gives time periods of 2.856 s and 0.4505s with a time step of 0.01.
# A smaller time step is required to obtain a closer match for the lower time periods/higher frequencies.
# A higher time step of 0.05 is used in this test to reduce testing time.

# The time history from this analysis matches with that obtained from Abaqus.

# Values from the first few time steps are as follows:
# time       disp_y            vel_y            accel_y
# 0     0.0                  0.0                0.0

# The dissolution reaction, with limited initial mineral concentration

#
# a' = -(mineral / porosity)' = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#
# The following parameters are used
#
# T_ref = 0.5 K
# T = 1 K
# activation_energy = 3 J/mol
# gas_constant = 6 J/(mol K)
# kinetic_rate_at_ref_T = 0.60653 mol/(m^2 s)
# These give rate = 0.60653 * exp(1/2) = 1 mol/(m^2 s)
#
# surf_area = 0.5 m^2/L
# molar_volume = 2 L/mol
# These give rate * surf_area * molar_vol = 1 s^-1
#
# equilibrium_constant = 0.5 (dimensionless)
# primary_activity_coefficient = 2 (dimensionless)
# stoichiometry = 1 (dimensionless)
# This means that 1 - (1 / eqm_const) * (act_coeff * a)^stoi = 1 - 4 a, which is positive for a < 0.25, ie dissolution for a(t=0) < 0.25
#
# The solution of the DE is
# a = eqm_const / act_coeff + (a(t=0) - eqm_const / act_coeff) exp(-rate * surf_area * molar_vol * act_coeff * t / eqm_const)
#   = 0.25 + (a(t=0) - 0.25) exp(-4 * t)
# c = c(t=0) - (a - a(t=0)) * porosity
#
# However, c(t=0) is small, so that the reaction only works until c=0, then a and c both remain fixed
#
# This test checks that (a + c / porosity) is time-independent, and that a follows the above solution, until c=0 and thereafter remains fixed.
#
# Aside:
#    The exponential curve is not followed exactly because moose actually solves
#    (a - a_old)/dt = rate * surf_area * molar_vol (1 - (1 / eqm_const) * (act_coeff * a)^stoi)
#    which does not give an exponential exactly, except in the limit dt->0

# A unit load is applied at the end of a cantilever beam of length 4m.
# The properties of the cantilever beam are as follows:
# Young's modulus (E) = 2.60072400269
# Shear modulus (G) = 1.0e4
# Poissons ratio (nu) = -0.9998699638
# Shear coefficient (k) = 0.85
# Cross-section area (A) = 0.554256
# Iy = 0.0141889 = Iz
# Length = 4 m

# For this beam, the dimensionless parameter alpha = kAGL^2/EI = 2.04e6

# The small deformation analytical deflection of the beam is given by
# delta = PL^3/3EI * (1 + 3.0 / alpha) = PL^3/3EI = 578 m

# Using 10 elements to discretize the beam element, the FEM solution is 576.866 m.
# The ratio beam FEM solution and analytical solution is 0.998.

# Beam is on the XY plane with load applied along the Z axis.

# This simulation models the mechanics solution for a hollow sphere under
# pressure, applied on the outer surfaces, using 1D spherical symmetry
# assumpitions.  The inner radius of the sphere, r = 4mm, is pinned to prevent
# rigid body movement of the sphere.
#
# From Bower (Applied Mechanics of Solids, 2008, available online at
# solidmechanics.org/text/Chapter4_1/Chapter4_1.htm), and applying the outer
# pressure and pinned displacement boundary conditions set in this simulation,
# the radial displacement is given by:
#
# u(r) = \frac{P(1 + v)(1 - 2v)b^3}{E(b^3(1 + v) + 2a^3(1-2v))} * (\frac{a^3}{r^2} - r)
#
# where P is the applied pressure, b is the outer radius, a is the inner radius,
# v is Poisson's ration, E is Young's Modulus, and r is the radial position.
#
# The radial stress is given by:
#
# S(r) = \frac{Pb^3}{b^3(1 + v) + 2a^3(1 - 2v)} * (\frac{2a^3}{r^3}(2v - 1) - (1 + v))
#
# The test assumes an inner radius of 4mm, and outer radius of 9 mm,
# zero displacement at r = 4mm, and an applied outer pressure of 2MPa.
# The radial stress is largest in the inner most element and, at an assumed
# mid element coordinate of 4.5mm, is equal to -2.545MPa.

# FluidFlower International Benchmark study model
# CSIRO 2023
#
# This example can be used to reproduce the results presented by the
# CSIRO team as part of this benchmark study. See
# Green, C., Jackson, S.J., Gunning, J., Wilkins, A. and Ennis-King, J.,
# 2023. Modelling the FluidFlower: Insights from Characterisation and
# Numerical Predictions. Transport in Porous Media.
#
# This example takes a long time to run! The large density contrast
# between the gas phase CO2 and the water makes convergence very hard,
# so small timesteps must be taken during injection.
#
# This example uses a simplified mesh in order to be run during the
# automated testing. To reproduce the results of the benchmark study,
# replace the simple layered input mesh with the one located in the
# large_media submodule.
#
# The mesh file contains:
# - porosity as given by FluidFlower description
# - permeability as given by FluidFlower description
# - subdomain ids for each sand type
#
# The nominal thickness of the FluidFlower tank is 19mm. To keep masses consistent
# with the experiment, porosity and permeability are multiplied by the thickness

# Mandel's problem of consolodation of a drained medium
# Using the FullySaturatedDarcyBase and FullySaturatedMassTimeDerivative kernels
#
# A sample is in plane strain.
# -a <= x <= a
# -b <= y <= b
# It is squashed with constant force by impermeable, frictionless plattens on its top and bottom surfaces (at y=+/-b)
# Fluid is allowed to leak out from its sides (at x=+/-a)
# The porepressure within the sample is monitored.
#
# As is common in the literature, this is simulated by
# considering the quarter-sample, 0<=x<=a and 0<=y<=b, with
# impermeable, roller BCs at x=0 and y=0 and y=b.
# Porepressure is fixed at zero on x=a.
# Porepressure and displacement are initialised to zero.
# Then the top (y=b) is moved downwards with prescribed velocity,
# so that the total force that is inducing this downwards velocity
# is fixed.  The velocity is worked out by solving Mandel's problem
# analytically, and the total force is monitored in the simulation
# to check that it indeed remains constant.
#
# Here are the problem's parameters, and their values:
# Soil width.  a = 1
# Soil height.  b = 0.1
# Soil's Lame lambda.  la = 0.5
# Soil's Lame mu, which is also the Soil's shear modulus.  mu = G = 0.75
# Soil bulk modulus.  K = la + 2*mu/3 = 1
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.2
# Soil bulk compliance.  1/K = 1
# Fluid bulk modulus.  Kf = 8
# Fluid bulk compliance.  1/Kf = 0.125
# Soil initial porosity.  phi0 = 0.1
# Biot coefficient.  alpha = 0.6
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 4.705882
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.694118
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.372627
# Skempton coefficient.  B = alpha*M/Ku = 1.048035
# Fluid mobility (soil permeability/fluid viscosity).  k = 1.5
# Consolidation coefficient.  c = 2*k*B^2*G*(1-nu)*(1+nuu)^2/9/(1-nuu)/(nuu-nu) = 3.821656
# Normal stress on top.  F = 1
#
# The solution for porepressure and displacements is given in
# AHD Cheng and E Detournay "A direct boundary element method for plane strain poroelasticity" International Journal of Numerical and Analytical Methods in Geomechanics 12 (1988) 551-572.

# Test for `StructureAcousticInterface` interface kernel. The domain is 1D with 20m
# length. The fluid domain is on the right and the structural domain is on the left.
# Fluid end is subjected to a 250Hz sine wave with a single peak of amplitude unity.
# Structural domain is 4 times as dense as the fluid domain with all other material
# properties being the same. Fluid pressure is recorded at the midpoint in the fluid
# domain (i.e., at 15m). Structural stress is recorded at the midpoint in the structural
# domain (i.e., at 5m). The recorded pressure and stress amplitudes should match
# with theoretical values.
#
# Input parameters:
# Dimensions = 1
# Length = 20 meters
# Fluid speed of sound = 1500 m/s
# Fluid density = 1e-6 Giga kg/m^3
# Structural bulk modulus = 2.25 GPa

# PorousFlow analogy of chemical_reactions/test/tests/solid_kinetics/2species_without_action.i
#
# Simple equilibrium reaction example to illustrate the use of PorousFlowAqueousPreDisChemistry
#
# In this example, two primary species a and b diffuse towards each other from
# opposite ends of a porous medium, reacting when they meet to form a mineral
# precipitate. The kinetic reaction is
#
# a + b = mineral
#
# where a and b are the primary species (reactants), and mineral is the precipitate.
# At the time of writing, the results of this test differ from chemical_reactions because
# in PorousFlow the mineral_concentration is measured in m^3 (precipitate) / m^3 (porous_material)
# in chemical_reactions the mineral_concentration is measured in m^3 (precipitate) / m^3 (fluid)
# ie, PorousFlow_mineral_concentration = porosity * chemical_reactions_mineral_concentration

# Uses a multi-smoothed version of capped-Mohr-Coulomb (via CappedMohrCoulombStressUpdate and ComputeMultipleInelasticStress) to simulate the following problem.
# A cubical block is notched around its equator.
# All of its outer surfaces have roller BCs, but the notched region is free to move as needed
# The block is initialised with a high hydrostatic tensile stress
# Without the notch, the BCs do not allow contraction of the block, and this stress configuration is admissible
# With the notch, however, the interior parts of the block are free to move in order to relieve stress, and this causes plastic failure
# The top surface is then pulled upwards (the bottom is fixed because of the roller BCs)
# This causes more failure

# Test that models bending of a cantilever beam using shell elements

# A cantilever beam of length 10 m (in Y direction) and cross-section
# 1 m x 0.1 m is modeled using 4 shell elements placed along the length
# (Figure 6a from Dvorkin and Bathe, 1984). All displacements and
# X rotations are fixed on the bottom boundary. E = 2100000 and v = 0.0.
# A load of 0.5 N (in the Z direction) is applied at each node on the top
# boundary resulting in a total load of 1 N.

# The analytical solution for displacement at tip using small strain/rotations # is PL^3/3EI + PL/AG = 1.90485714 m
# The FEM solution using 4 shell elements is 1.875095 m with a relative error
# of 1.5%.

# Similarly, the analytical solution for slope at tip is PL^2/2EI = 0.285714286
# The FEM solution is 0.2857143 and the relative error is 5e-6%.

# The stress_yy for the four elements at z = -0.57735 * (t/2) (first qp below mid-surface of shell) are:
# 3031.089 Pa, 2165.064 Pa, 1299.038 Pa and 433.0127 Pa.
# Note the above values are the average stresses in each element.

# Analytically, stress_yy decreases linearly from y = 0 to y = 10 m.
# The maximum value of stress_yy at y = 0 is Mz/I = PL * 0.57735*(t/2)/I = 3464.1 Pa
# Therefore, the analytical value of stress at z = -0.57735 * (t/2) at the mid-point
# of the four elements are:
# 3031.0875 Pa, 2165.0625 Pa, 1299.0375 Pa ,433.0125 Pa

# The relative error in stress_yy is in the order of 5e-5%.

# The stress_yz at z = -0.57735 * (t/2) at all four elements from the simulation is 10 Pa.
# The analytical solution for the shear stress is: V/2/I *((t^2)/4 - z^2), where the shear force (V)
# is 1 N at any y along the length of the beam. Therefore, the analytical shear stress at
# z = -0.57735 * (t/2) is 10 Pa at any location along the length of the beam.

# Simple equilibrium reaction example to illustrate the use of the AqueousEquilibriumReactions
# action.
# In this example, a single primary species a is transported by diffusion and convection
# from the left of the porous medium, reacting to form an equilibrium species pa2 according to
# the equilibrium reaction specified in the AqueousEquilibriumReactions block as:
#
#  reactions = '2a = pa2 1'
#
# where the 2 is the weight of the equilibrium species, and the 1 refers to the equilibrium
# constant (log10(Keq) = 1).
#
# The AqueousEquilibriumReactions action creates all the required kernels and auxkernels
# to compute the reaction given by the above equilibrium reaction equation.
#
# Specifically, it adds to following:
# * An AuxVariable named 'pa2' (given in the reactions equations)
# * A AqueousEquilibriumRxnAux AuxKernel for this AuxVariable with all parameters
# * A CoupledBEEquilibriumSub Kernel for each primary species with all parameters
# * A CoupledDiffusionReactionSub Kernel for each primary species with all parameters
# * A CoupledConvectionReactionSub Kernel for each primary species with all parameters if
# pressure is a coupled variable
