The weak form of this equation, in inner-product notation, is given by:

$var element = document.getElementById("moose-equation-761e1aa8-e556-4769-a58b-a936b70a4f22");katex.render("R_i(u_h) = (\\nabla \\psi_i, \\nabla u_h) = 0 \\quad \\forall \\psi_i,", element, {displayMode:true,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});$ where $var element = document.getElementById("moose-equation-85fb6310-8c91-46e0-9433-c3eb1e114ad9");katex.render("\\psi_i", element, {displayMode:false,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});$ are the test functions and $var element = document.getElementById("moose-equation-f3810bc6-7f08-461f-9fe0-058b1e27b07c");katex.render("u_h \\in \\mathcal{S}^h", element, {displayMode:false,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});$ is the finite element solution of the weak formulation.

The Jacobian is defined as:

$var element = document.getElementById("moose-equation-d54177e1-e219-45f6-b41f-45534e9a0992");katex.render("\\frac{\\partial R_i(u_h)}{\\partial u_j} = (\\nabla \\phi_i, \\nabla \\psi_j).", element, {displayMode:true,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});$

# T_ref = 0.5 K

# activation_energy = 3 J/mol

# surf_area = 0.5 m^2/L

#
# equilibrium_constant = 0.5 (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

# there are 5 Sub Apps which correspond to each vertex of the unit square
# and the center, arranged in the following order:
# 3   4
#   2
# 0   1
# Sub Apps 0, 1, 3, and 4 currently overlap with a single element in
# each corner of the Master App, while Sub App 2 overlaps with 4
# Master App elements in the center. Note that we move the corner Sub
# Apps "outward" slightly along the diagonals to avoid ambiguity with
# which SubApp is "nearest" to a given Master App element centroid.

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
# p = n * R * / (V_cavity / T_cavity + V_add / T_add)
# where
#  p is the pressure
#  n is the amount of material in the volume (moles)
#  R is the universal gas constant
#  T_cavity is the temperature in the cavity
#  T_add is the temperature of the additional volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
#   Block 2 sits in the cavity and has a volume of 1.  Thus, the total
#   initial volume is 7. An additional volume of 2 is added.
#
# The test adjusts n, T, and V in the following way:
#   n => n0 + alpha * t
#   T => T0 + beta * t
#   V => V_cavity0 + gamma * t + V_add
# with
#   alpha = n0
#   beta = T0 / 2
#   gamma = -(0.003322259...) * V0
#   T0 = 240.54443866068704
#   V_cavity0 = 7
#   V_add = 2
#   T_add = 100
#   n0 = f(p0)
#   p0 = 100
#   R = 8.314472 J * K^(-1) * mol^(-1)
#
#  An additional volume of 2 with a temperature of 100.0 is included.
#
# So, n0 = p0 * (V_cavity / T_cavity + V_add / T_add) / R
#        = 100 * (7 / 240.544439 + 2 / 100) / 8.314472
#        = 0.59054
#
# The parameters combined at t = 1 gives p = 249.647.
#
# This test sets the initial temperature to 500, but the CavityPressure
#   is told that that initial temperature is T0.  Thus, the final solution
#   is unchanged.

# ---------------------------------------------------------------------------
# This test is designed to verify the variable elasticity tensor functionality in the
# ComputeFiniteStrainElasticStress 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.
#
#    Temperature(K)   strain_{xx}(m/m)     Young's Modulus(Pa)   stress_{xx}(Pa)
#          400              0.001             10.0e6               1.0e4
#          500              0.001             10.0e6               1.0e4
#          600              0.001              9.94e6              9.94e3

#
#    The tensor mechanics results align exactly with the analytical results above
#    when this test is run with ComputeIncrementalSmallStrain.  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.

# 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
#
# This input file solves no useful physics: it is just illustrating the above point

# There are four variables and four functions of the same name, u,v,w, and A.  The diffusion equation is solved
# for each of these variables with a boundary condition of type FunctionDirchletBC applied to a boundary
# (i.e. node set) that includes every node in the element.  Each boundary condition uses a function of type
# PiecewiseBilinear that gets its value from a file named fred.csv.
#
# fred is a matrix of data whose first row and first column are vectors that can refer to either spacial positions
# corresponding to an axis or values of time.  The remaining data are values of fred for a given row and column pair.
#
#
# Visualize fred like this:
#
#                          0 1 3  where fred is a csv file that actually looks like this    0,1,3
#                        0 0 0 0                                                            0,0,0,0
#                        1 0 1 3                                                            1,0,1,3
#                        3 0 5 7                                                            3,0,5,7
#
#  Another way to think of fred is:
#
#                                   |0 1 3| - These values can be spacial positions corresponding to
#                                             axis= 0,1, or 2, or time
#
#
#                           |0|     |0 0 0|
#     These values can be - |1|     |0 1 3| - values of fred corresponding to row-column pairs
#     time or spacial       |3|     |0 5 7|
#     positions corresponding
#     to axis= 0,1, or 2
#
#
# The parameters and possible values for the function PiecewiseBilinear are:
#
# data_file = fred.csv
# axis = 0, 1, or 2
# xaxis = 0, 1, or 2
# yaxis = 0, 1, or 2
# radial = true or false (false is default)
#
# where 0, 1, or 2 refer to the x, y, or z axis.
#
# If the parameter axis is defined, then the first row of fred are spacial position and the first column
# of fred are the values of time.
#
# If the parameter xaxis is defined, then the first row of fred are spacial positions and the first column
# of fred are the values of time ... just like defining the parameter axis.
#
# If the parameter yaxis is defined, then the first row of fred are time values and the first column of fred
# are spacial positions.
#
# If parameters axis AND EITHER xaxis or yaxis are defined together you'll get a moose error.
# i.e.
# axis = 0
# xaxis = 1
# results in an error.  So, if you use the parameter axis, don't use xaxis or yaxis.
#
# If parameters xaxis and yaxis are defined (and radial is false), then the first row of fred are spacial positions corresponding to xaxis value,
# and the first column are spacial positions corresponding to the yaxis value.
#
# If xaxis and yaxis are defined and radial is true, the first row of fred contains values
# corresponding to the radius calculated from the coordinates of each point.  Note that
# the definition of xaxis and yaxis define the "plane" of the radius.  For example,
# xaxis = 0 and yaxis = 1 means that x and y components of the point are use to
# calculate the radius.  xaxis = 1 and yaxis = 2 means that x and z components are used.
# The first column is for time in this case.  xaxis and yaxis have to be specified and
# radial = true for this to work, otherwise a MOOSE error will result.
# This was developed so that an axisymmetric function could be defined for a 3D mesh.

#
# The mesh consists of two blocks.  Block 1 has a height and width of 1 whereas
# block 2 has a height of 2 and width of 1. A gap of 1 exists between the two
# blocks in the x direction.  Elements are 0.25 high and 1 wide.  The solution
# in block 1 is u = y and block 2 is u = 4y.
#
# Two sets of LayeredAverage values are computed.  In both cases, four
# layers are used.  In 'bounding_block1', the LayeredAverage values are computed
# on block 1 using the bounds (dimensions of block 2). In 'bounding_block2',
# the LayeredAverage values are computed on block 2 using the bounds (dimensions
# of block 1).
#
# In 'bounding_block1', since the layers are defined by the dimensions of block
# 2 only two layers appear in block one.  The values in block 1 are thus:
# 0.25 for 0<y<0.5 and 0.75 for 0.5<y<1.
#
# In 'bounding_block2', since the layers are defined by the dimensions of block
# 1 four layers appear in block two. Any place over and above the top of the
# uppermost layer is included in the uppermost layer.  Therefore, the first 3
# layers are 1/4 of the height of block 1 (0.25) whereas the 4th layer has a
# height of 1/4 of block 1 (0.25) plus the additional region in block 2 outside
# the bounds of block 1 (1.0) for a total height of 1.24.
# The values in block 2 are thus:
# 0.5 from 0<y<0.25, 1.5 from 0.25<y<0.5, 2.5 from 0.5<y<0.75, and 5.5 from
# y>0.75.

# 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

# This is testing a scenario where volumetric system (like kernels) asks for second derivatives
# and the formulation includes a system using neighbor elements (like DGKernels or
# InterfaceKernels)
# If the latter did not request the second derivatives MOOSE should not be computing those.
# The PDEs solved are quite contrived, the Biharmonic kernel is there just to trigger the

#
# This test checks the generalized plane strain using small strain formulation.
# The model consists of two sets of line elements. One undergoes a temperature rise of 100 with
# the other seeing a temperature rise of 300.  Young's modulus is 3600, and
# Poisson's ratio is 0.2.  The thermal expansion coefficient is 1e-8.  All
# nodes are constrained against movement.
#
# For plane strain case, i.e., without constraining the strain_yy to be uniform,
# the stress solution would be [-6e-3, -6e-3, -6e-3] and [-18e-3, -18e-3, -18e-3] (xx, yy, zz).
# The generalized plane strain kernels work to balance the force in y direction.
#
# With out of plane strain of 3e-6, the stress solution becomes
# [-3e-3, 6e-3, -3e-3] and [-15e-3, -6e-3, -15e-3] (xx, yy, zz).  This gives
# a domain integral of out-of-plane stress to be zero.

#
# This test checks the generalized plane strain using incremental small strain formulation.
# The model consists of two sets of line elements. One undergoes a temperature rise of 100 with
# the other seeing a temperature rise of 300.  Young's modulus is 3600, and
# Poisson's ratio is 0.2.  The thermal expansion coefficient is 1e-8.  All
# nodes are constrained against movement.
#
# For plane strain case, i.e., without constraining the strain_yy to be uniform,
# the stress solution would be [-6e-3, -6e-3, -6e-3] and [-18e-3, -18e-3, -18e-3] (xx, yy, zz).
# The generalized plane strain kernels work to balance the force in y direction.
#
# With out of plane strain of 3e-6, the stress solution becomes
# [-3e-3, 6e-3, -3e-3] and [-15e-3, -6e-3, -15e-3] (xx, yy, zz).  This gives
# a domain integral of out-of-plane stress to be zero.

# In this test, the Master App is a 10x10 grid on the unit square, and
# there are 5 Sub Apps which correspond to each vertex of the unit square
# and the center, arranged in the following order:
# 3   4
#   2
# 0   1
# Sub Apps 0, 1, 3, and 4 currently overlap with a single element in
# each corner of the Master App, while Sub App 2 overlaps with 4
# Master App elements in the center. Note that we move the corner Sub
# Apps "outward" slightly along the diagonals to avoid ambiguity with
# which SubApp is "nearest" to a given Master App element centroid.
# This makes it easier to visually verify that the Transfers are
# working correctly.

# There are four variables and four functions of the same name, u,v,w, and A.  The diffusion equation is solved
# for each of these variables with a boundary condition of type FunctionDirchletBC applied to a boundary
# (i.e. node set) that includes every node in the element.  Each boundary condition uses a function of type
# PiecewiseBilinear that gets its value from the specified x, y, and z values.
#
# fred is a matrix of data whose first row and first column are vectors that can refer to either spacial positions
# corresponding to an axis or values of time.  The remaining data are values of fred for a given row and column pair.
#
#
# Visualize fred like this:
#
#                          0 1 3  where fred is a csv file that actually looks like this    0,1,3
#                        0 0 0 0                                                            0,0,0,0
#                        1 0 1 3                                                            1,0,1,3
#                        3 0 5 7                                                            3,0,5,7
#
#  Another way to think of fred is:
#
#                                   |0 1 3| - These values can be spacial positions corresponding to
#                                             axis= 0,1, or 2, or time
#
#
#                           |0|     |0 0 0|
#     These values can be - |1|     |0 1 3| - values of fred corresponding to row-column pairs
#     time or spacial       |3|     |0 5 7|
#     positions corresponding
#     to axis= 0,1, or 2
#
#
# The parameters and possible values for the function PiecewiseBilinear are:
#
# x = '0 1 3'
# y = '0 1 3'
# z = '0 0 0 0 1 3 0 5 7'
# axis = 0, 1, or 2
# xaxis = 0, 1, or 2
# yaxis = 0, 1, or 2
# radial = true or false (false is default)
#
# where 0, 1, or 2 refer to the x, y, or z axis.
#
# If the parameter axis is defined, then the first row of fred are spacial position and the first column
# of fred are the values of time.
#
# If the parameter xaxis is defined, then the first row of fred are spacial positions and the first column
# of fred are the values of time ... just like defining the parameter axis.
#
# If the parameter yaxis is defined, then the first row of fred are time values and the first column of fred
# are spacial positions.
#
# If parameters axis AND EITHER xaxis or yaxis are defined together you'll get a moose error.
# i.e.
# axis = 0
# xaxis = 1
# results in an error.  So, if you use the parameter axis, don't use xaxis or yaxis.
#
# If parameters xaxis and yaxis are defined (and radial is false), then the first row of fred are spacial positions corresponding to xaxis value,
# and the first column are spacial positions corresponding to the yaxis value.
#
# If xaxis and yaxis are defined and radial is true, the first row of fred contains values
# corresponding to the radius calculated from the coordinates of each point.  Note that
# the definition of xaxis and yaxis define the "plane" of the radius.  For example,
# xaxis = 0 and yaxis = 1 means that x and y components of the point are use to
# calculate the radius.  xaxis = 1 and yaxis = 2 means that x and z components are used.
# The first column is for time in this case.  xaxis and yaxis have to be specified and
# radial = true for this to work, otherwise a MOOSE error will result.
# This was developed so that an axisymmetric function could be defined for a 3D mesh.

# This input file illustrates that PorousFlow can be block-restricted.  That is, porous-flow physics acts only on some blocks (block = '0, 1', in this case), and different physics, in this case diffusion, acts on other blocks (block = 2, in this case).
# Here:
# - the Variable "pressure" exists everywhere, but is governed by PorousFlow only on block = '0 1', and diffusion on block = 2
# - the Variable "temp" exists only on block = '0 1', and is governed by PorousFlow there
# - the Variable "temp1" exists only on block = 2, and is governed by diffusion there
# Hence, the PorousFlow Materials only need to be defined on block = '0 1'

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
#   p = n * R * T / V
# where
#   p is the pressure
#   n is the amount of material in the volume (moles)
#   R is the universal gas constant
#   T is the temperature
#   V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
#   Block 2 sits in the cavity and has a volume of 1.  Thus, the total
#   initial volume is 7.
# The test adjusts n, T, and V in the following way:
#   n => n0 + alpha * t
#   T => T0 + beta * t
#   V => V0 + gamma * t
# with
#   alpha = n0
#   beta = T0 / 2
#   gamma = - (0.003322259...) * V0
#   T0 = 240.54443866068704
#   V0 = 7
#   n0 = f(p0)
#   p0 = 100
#   R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
#        = 0.35
#
# The parameters combined at t = 1 gives p = 301.

# 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".

# This tests the capability of the code to read input files in csv or space separated format.
# There are four variables and four functions of the same name; a,b,c, and d.  The diffusion equation is "solved"
# for each of these variables with a boundary condition of type FunctionDirchletBC applied to a boundary
# (i.e. node set) that includes every node in the element, so the solution is the boundary condition defined by the function.
#  Each boundary condition uses a function of type PiecewiseLinear that gets its value from a file,
# which could be in comma separated or space separated format.  The input file can also contain comments.
#
# The files could have the form
# 0,1,2,3 # time
# 0,4,5,6 # bc value
# for format = row
# or
# 0,0
# 1,4
# 2,5
# 3,6
# for format = column
# Values in files could be separated by white space.  See the .csv and .dat files for format examples.
#
# The value of the variables should correspond to the function.
# At time = 0, the variable = 0, at time = 1, variable = 4 and so on.

# Test for `StructureAcousticInterface` interface kernel. The domain is 3D with lengths
# 10 X 0.1 X 0.1 meters. 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.
# 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
# pressure and structural stress should be almost equal and opposite to each other.
#
# Input parameters:
# Dimensions = 3
# Lengths = 10 X 0.1 X 0.1 meters
# Fluid speed of sound = 1500 m/s
# Fluid density = 1e-6 Giga kg/m^3
# Structural bulk modulus = 2.25 GPa
# Structural shear modulus = 0 GPa

#
# Cavity Pressure Test (Volume input as a vector of postprocessors)
#
# This test is designed to compute an internal pressure based on
#   p = n * R * T / V
# where
#   p is the pressure
#   n is the amount of material in the volume (moles)
#   R is the universal gas constant
#   T is the temperature
#   V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
#   Block 2 sits in the cavity and has a volume of 1.  Thus, the total
#   initial volume is 7.
# The test adjusts n, T, and V in the following way:
#   n => n0 + alpha * t
#   T => T0 + beta * t
#   V => V0 + gamma * t
# with
#   alpha = n0
#   beta = T0 / 2
#   gamma = - (0.003322259...) * V0
#   T0 = 240.54443866068704
#   V0 = 7
#   n0 = f(p0)
#   p0 = 100
#   R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
#        = 0.35
#
# In this test the internal volume is calculated as the sum of two Postprocessors
# internalVolumeInterior and internalVolumeExterior.  This sum equals the value
# reported by the internalVolume postprocessor.
#
# The parameters combined at t = 1 gives p = 301.

# This is a test of the ForcingFunctionAux AuxKernel.
# The diffusion equation for u is solved with boundary conditions to force a gradient
# du/dx = 2, which is constant in time.
# du/dx is integrated over the unit square domain using a postprocessor, resulting in 2.
# The value of this postprocessor is supplied to the forcing function f used by
# the ForcingFunctionAux AuxKernel, which increments the AuxVariable T.
# Since the time step is 1, the value of T increases by 2 for each time step.

# 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

# This test covers the usage of the VariableTimeIntegrationAux
# kernel. Here we test three different schemes for integrating a field
# variable in time.  Midpoint, Trapezoidal, and Simpson's rule are
# used.  For this test, we use a manufactured solution and we compare
# the Trapezoidal and Simpson's rule, which must be exact for this
# exact solution, which is a linear function of time.
#
# The set up problem is
#
#  du/dt - Laplacian(u) = Q
#
# with exact solution: u = t*(x*x+y*y).

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
#   p = n * R * T / V
# where
#   p is the pressure
#   n is the amount of material in the volume (moles)
#   R is the universal gas constant
#   T is the temperature
#   V is the volume
#
# The mesh is composed of one block (2) with an interior cavity of volume 8.
#   Block 1 sits in the cavity and has a volume of 1.  Thus, the total
#   initial volume is 7.
# The test adjusts T in the following way:
#   T => T0 + beta * t
# with
#   beta = T0
#   T0 = 240.54443866068704
#   V0 = 7
#   n0 = f(p0)
#   p0 = 100
#   R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
#        = 0.35
#
# At t = 1, p = 200.

# 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

# 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 checks that material properties are correctly implicitly be
# promoted to "stateful" when a stateful old or older value is requested for
# them even when the properties were never explicitly declared with old/older
# support.  So the ImplicitStateful material simply requests stateful
# old/older values from a generic constant material that doesn't declare its
# material property with old/older support.  This material adds the current
# simulation time to that to calculate its own material property. A second
# implicit stateful material requests the older value of the firsts stateful
# material - also not declared to support old/older as its material property
# value.  The sequence of material properties generated by the second implicit
# stateful material should be delayed by the first's by one time step.

#
# Cavity Pressure Test
#
# This test is designed to compute an internal pressure based on
#   p = n * R * T / V
# where
#   p is the pressure
#   n is the amount of material in the volume (moles)
#   R is the universal gas constant
#   T is the temperature
#   V is the volume
#
# The mesh is composed of one block (1) with an interior cavity of volume 8.
#   Block 2 sits in the cavity and has a volume of 1.  Thus, the total
#   initial volume is 7.
# The test adjusts n, T, and V in the following way:
#   n => n0 + alpha * t
#   T => T0 + beta * t
#   V => V0 + gamma * t
# with
#   alpha = n0
#   beta = T0 / 2
#   gamma = -(0.003322259...) * V0
#   T0 = 240.54443866068704
#   V0 = 7
#   n0 = f(p0)
#   p0 = 100
#   R = 8.314472 J * K^(-1) * mol^(-1)
#
# So, n0 = p0 * V0 / R / T0 = 100 * 7 / 8.314472 / 240.544439
#        = 0.35
#
# The parameters combined at t = 1 gives p = 301.
#
# This test sets the initial temperature to 500, but the CavityPressure
#   is told that that initial temperature is T0.  Thus, the final solution
#   is unchanged.
