Controllable:No
Description:The name of the variable that this object applies to
MaterialStdVectorAux
Extracts a component of a material type std::vector<Real> to an aux variable. If the std::vector is not of sufficient size then zero is returned
Converting a field from the material system, here a component of a vector material property, to a variable may be desirable for several reasons: to match the format expected by certain kernels (thus lagging the field between time steps) or for output/testing/debugging.
This is particularly useful to examine anisotropic material properties. For output purposes only, an alternative is to use the output_properties argument of the Material or specify output_material_properties in the parameters of the desired output type nested in the [Outputs] block. This AuxKernel is used in the back-end by these parameters.
commentnote
The MaterialRealVectorValueAux provides similar functionality.
commentnote
The AD system currently does not support auxiliary variables. If you convert material properties, which do support automatic differentiation, to auxiliary variables, the derivatives will be ignored.
Example syntax
In this example, the MaterialStdVectorAux is being used to examine the first component of an anisotropic permeability.
[relpermwater]
type = MaterialStdVectorAux
property = PorousFlow_relative_permeability_qp

Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:Yes
Description:Set the enabled status of the MooseObject.
- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary. In the default nearest_node_connected_sides algorithm, primary boundary elements are searched iff that nearest node is one of their nodes. This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).

# 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.

# Using TensileStressUpdate
# checking for small deformation
# A single element is stretched equally in all directions.
# This causes the return direction to be along the sigma_I = sigma_II = sigma_III line
# tensile_strength is set to 1Pa, and smoothing_tol = 0.1Pa
# The smoothed yield function comes from two smoothing operations.
# The first is on sigma_I and sigma_II (sigma_I >= sigma_II >= sigma_III):
# yf = sigma_I + ismoother(0) - tensile_strength
# = sigma_I + (0.5 * smoothing_tol - smoothing_tol / Pi) - tensile_strength
# = sigma_I + 0.018169 - 1
# The second has the argument of ismoother equal to -0.018169.
# ismoother(-0.018169) = 0.5 * (-0.018169 + 0.1) - 0.1 * cos (0.5 * Pi * -0.018169 / 0.1) / Pi
# = 0.010372
# So the final yield function is
# yf = sigma_I + 0.018169 + 0.010372 - 1 = sigma_I + 0.028541 - 1
# However, because of the asymmetry in smoothing (the yield function is obtained
# by first smoothing sigma_I-ts and sigma_II-ts, and then by smoothing this
# result with sigma_III-ts) the result is sigma_I = sigma_II > sigma_III

# 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

# 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

# Use ComputeMultipleInelasticStress with two inelastic models: CappedDruckerPrager and CappedWeakPlane.
# The relative_tolerance and absolute_tolerance parameters are set small so that many
# Picard iterations need to be performed.
#
# The CappedDruckerPrager has tensile strength 3E2 and large cohesion,
# and the return-map sets stress = trial_stress - diag(d, d, d), for
# some d to be determined
# The CappedWeakPlane has tensile strength zero and large cohesion,
# and the return-map sets stress = diag(t - v*w/(1-v), t - v*w/(1-v), t - w)
# where t is trial stress, v is Poisson's ratio, and w is to be determined
#
# d and w are determined by demanding that the final stress shouldn't depend
# on the order of return-mapping (DP first then WP, or WP first then DP).
#
# Let the initial_stress = diag(I, I, I).
# The returned stress is diag(I - d - v*w/(1-v), I - d - v*w/(1-v), I - d - w). This
# must obey Tr(stress) <= dp_tensile_strength, and I-d-w <= wp_tensile_strength.
#
# For I = 1E3, and v = 0.2, the solution is d = 800 and w = 200, with

# 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

# 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.

# Young = 10.0
# Poisson = 0.25
# layer_thickness = 10
# joint_normal_stiffness = 2.5
# joint_shear_stiffness = 2.0
# These give the following nonzero components of the elasticity tensor:

# E_0011 = E_1100 = 3.855855855856E+00
# E_2222 = E_pp = 8.108108108108E+00

# Gt = E_qq = E_0202 = E_0220 = E_2002 = E_1212 = E_1221 = E_2112 = 3.333333333333E+00
# E_2020 = E_2121 = 3.666666666667E+00
# They give the following nonzero components of the bending rigidity tensor:
# D = 8.888888888889E+02
# B_0101 = B_1010 = 8.080808080808E+00
# B_0110 = B_1001 = -2.020202020202E+00
#
# 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
# omega_x = omega_y = omega_z = 0
# yields the following strains:
# strain_xz = 32*t/Gt = 9.6*t
# strain_yz = 24*t/Gt = 7.2*t
# strain_zz = 10*t/E_2222 = 1.23333333*t
# and all other components, and the curvature, are zero.
# 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.
# Although this has resulted in a non-symmetric stress tensor, the
# moments generated are cancelled by the boundary conditions on
# omega_x and omega_y. (Removing these boundary conditions results
# in a symmetric stress tensor, and some omega!=0 being generated.)
# No moment stresses are generated because omega=0=curvature.
#
# The total strains are given above (strain_xz = 9.6,
# strain_yz = 7.2 and strain_zz = 1.23333).
# Since q returned from 40 to 20, plastic_strain_xz = strain_xz/2 = 4.8
# and plastic_strain_yz = strain_yz/2 = 3.6.
# Since p returned to zero, all of the total strain_zz is
# plastic, ie plastic_strain_zz = 1.23333

# 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

# Plastic deformation. Layered Cosserat with parameters:
# Young = 1.0
# Poisson = 0.2
# layer_thickness = 0.1
# joint_normal_stiffness = 0.25
# joint_shear_stiffness = 0.2
# These give the following nonzero components of the elasticity tensor:
# E_0000 = E_1111 = 1.043195
# E_0011 = E_1100 = 0.260799
# E_2222 = 0.02445
# E_0022 = E_1122 = E_2200 = E_2211 = 0.006112
# G = E_0101 = E_0110 = E_1001 = E_1010 = 0.416667
# Gt = E_0202 = E_0220 = E_2002 = E_1212 = E_1221 = E_2112 = 0.019084
# E_2020 = E_2121 = 0.217875
# They give the following nonzero components of the bending rigidity tensor:
# D = 8.68056E-5
# B_0101 = B_1010 = 7.92021E-4
# B_0110 = B_1001 = -1.584E-4

# Applying the following deformation to the zmax surface of a unit cube:
# disp_x = 8*t
# disp_y = 6*t
# disp_z = -t
# omega_x = omega_y = omega_z = 0
# yields the following strains:
# strain_xz = 8*t
# strain_yz = 6*t
# strain_zz = -t
# and all other components, and the curvature, are zero.
# The nonzero components of stress are therefore:
# stress_xx = stress_yy = -0.006112*t
# stress_xz = stress_zx = 0.152671*t
# stress_yz = stress_zy = 0.114504*t
# stress_zz = -0.0244499*t
# The moment stress is zero.
# So q = 0.19084*t and p = -0.0244*t.
#
# With large cohesion, but compressive strength = 0.0244499, the
# system is elastic up to t=1. After that time
# stress_zz = -0.0244499 (for t>=1)
# and
# stress_xx = stress_yy = -0.006112 (for t>=1), since the
# elastic trial increment is exactly canelled by the Poisson's
# contribution from the return to the yield surface.
# The plastic strains are zero for t<=1, but for larger times:
# plastic_strain_zz = - (t - 1) (for t>=1)

# 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.

# 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

# Plastic deformation. Layered Cosserat with parameters:
# Young = 1.0
# Poisson = 0.2
# layer_thickness = 0.1
# joint_normal_stiffness = 0.25
# joint_shear_stiffness = 0.2
# These give the following nonzero components of the elasticity tensor:
# E_0000 = E_1111 = 1.043195
# E_0011 = E_1100 = 0.260799
# E_2222 = 0.02445
# E_0022 = E_1122 = E_2200 = E_2211 = 0.006112
# G = E_0101 = E_0110 = E_1001 = E_1010 = 0.416667
# Gt = E_0202 = E_0220 = E_2002 = E_1212 = E_1221 = E_2112 = 0.019084
# E_2020 = E_2121 = 0.217875
# They give the following nonzero components of the bending rigidity tensor:
# D = 8.68056E-5
# B_0101 = B_1010 = 7.92021E-4
# B_0110 = B_1001 = -1.584E-4
#
# Applying the following deformation to the zmax surface of a unit cube:
# disp_x = 8*t
# disp_y = 6*t
# disp_z = t
# omega_x = omega_y = omega_z = 0
# yields the following strains:
# strain_xz = 8*t
# strain_yz = 6*t
# strain_zz = t
# and all other components, and the curvature, are zero.
# The nonzero components of stress are therefore:
# stress_xx = stress_yy = 0.006112*t
# stress_xz = stress_zx = 0.152671*t
# stress_yz = stress_zy = 0.114504*t
# stress_zz = 0.0244499*t
# The moment stress is zero.
# So q = 0.19084*t and p = 0.0244*t.
#
# With large cohesion, but tensile strength = 0.0244499, the
# system is elastic up to t=1. After that time
# stress_zz = 0.0244499 (for t>=1)
# and
# stress_xx = stress_yy = 0.006112 (for t>=1), since the
# elastic trial increment is exactly canelled by the Poisson's
# contribution from the return to the yield surface.
# The plastic strains are zero for t<=1, but for larger times:
# plastic_strain_zz = (t - 1) (for t>=1)

# 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

# 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

# Young = 10.0

# layer_thickness = 10
# joint_normal_stiffness = 2.5

# These give the following nonzero components of the elasticity tensor:

# E_0011 = E_1100 = 3.855855855856E+00

# Gt = E_qq = E_0202 = E_0220 = E_2002 = E_1212 = E_1221 = E_2112 = 3.333333333333E+00
# E_2020 = E_2121 = 3.666666666667E+00
# They give the following nonzero components of the bending rigidity tensor:
# D = 8.888888888889E+02
# B_0101 = B_1010 = 8.080808080808E+00
# B_0110 = B_1001 = -2.020202020202E+00
#
# 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

# Uses non-smoothed Mohr-Coulomb (via ComputeMultiPlasticityStress 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

# 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.

# Use ComputeMultipleInelasticStress with two inelastic models: CappedDruckerPrager and CappedWeakPlane.
# The relative_tolerance and absolute_tolerance parameters are set very large so that
# only one iteration is performed. This is the algorithm that FLAC uses to model
# jointed rocks, only Capped-Mohr-Coulomb is used instead of CappedDruckerPrager
#
# In this test "cycle_models=true" so that in the first timestep only
# CappedDruckerPrager is used, while in the second timestep only
# CappedWeakPlane is used.
#
# initial_stress = diag(1E3, 1E3, 1E3)
# The CappedDruckerPrager has tensile strength 3E2 and large cohesion,
# so the stress initially returns to diag(1E2, 1E2, 1E2)
# The CappedWeakPlane has tensile strength zero and large cohesion,
# so the stress returns to diag(1E2 - v/(1-v)*1E2, 1E2 - v/(1-v)*1E2, 0)
# where v=0.2 is the Poisson's ratio

# 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

# 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

# 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,

# Using CappedMohrCoulomb with compressive failure only

# A single element is stretched equally in all directions.
# This causes the return direction to be along the sigma_I = sigma_II = sigma_III line
# compressive_strength is set to 1Pa, and smoothing_tol = 0.1Pa
# The smoothed yield function comes from two smoothing operations.
# The first is on sigma_I and sigma_II (sigma_I >= sigma_II >= sigma_III):
# yf = -sigma_I + ismoother(0) - compressive_strength
# = -sigma_I + (0.5 * smoothing_tol - smoothing_tol / Pi) - compressive_strength
# = -sigma_I + 0.018169 - 1
# The second has the argument of ismoother equal to -0.018169.
# ismoother(-0.018169) = 0.5 * (-0.018169 + 0.1) - 0.1 * cos (0.5 * Pi * -0.018169 / 0.1) / Pi
# = 0.010372
# So the final yield function is
# yf = -sigma_I + 0.018169 + 0.010372 - 1 = -sigma_I + 0.028541 - 1
# However, because of the asymmetry in smoothing (the yield function is obtained
# by first smoothing -sigma_I-cs and -sigma_II-cs, and then by smoothing this
# result with -sigma_III-cs) the result is sigma_I > sigma_II = sigma_III

# 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

# Using CappedMohrCoulomb with tensile failure only
# checking for small deformation
# A single element is stretched equally in all directions.
# This causes the return direction to be along the sigma_I = sigma_II = sigma_III line
# tensile_strength is set to 1Pa, and smoothing_tol = 0.1Pa
# The smoothed yield function comes from two smoothing operations.
# The first is on sigma_I and sigma_II (sigma_I >= sigma_II >= sigma_III):
# yf = sigma_I + ismoother(0) - tensile_strength
# = sigma_I + (0.5 * smoothing_tol - smoothing_tol / Pi) - tensile_strength
# = sigma_I + 0.018169 - 1
# The second has the argument of ismoother equal to -0.018169.
# ismoother(-0.018169) = 0.5 * (-0.018169 + 0.1) - 0.1 * cos (0.5 * Pi * -0.018169 / 0.1) / Pi
# = 0.010372
# So the final yield function is
# yf = sigma_I + 0.018169 + 0.010372 - 1 = sigma_I + 0.028541 - 1
# However, because of the asymmetry in smoothing (the yield function is obtained
# by first smoothing sigma_I-ts and sigma_II-ts, and then by smoothing this
# result with sigma_III-ts) the result is sigma_I = sigma_II > sigma_III

# 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

# 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

# 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

# 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
