- variableThe name of the variable that this postprocessor operates on
C++ Type:std::vector<VariableName>
Unit:(no unit assumed)
Controllable:No
Description:The name of the variable that this postprocessor operates on
ElementExtremeValue
Finds either the min or max elemental value of a variable over the domain.
You can optionally provide a "proxy_variable", which will change the behavior of this postprocessor to find the quadrature point at which the proxy variable reaches the max/min value, and then return the value of the specified variable at that point.
This postprocessor can operate on both elemental and nodal variables. Note, however, that since it works by sampling the variable at the quadrature points, its returned value won't exactly match the variable's extreme value on the domain (or blocks) the postprocessor is defined over. This is the case, unless that extremum happens to be at a quadrature point, e.g., if the variable is constant over any given element. An alternative scheme is provided by ElementExtremeFunctorValue, which instead of sampling the variable at the quadrature points, samples the variable at the centroid of each element in the domain (or blocks) of interest. The corresponding postprocessor that finds (exact) extreme values of nodal variables evaluated at nodes is NodalExtremeValue.

# F=0.5 G=0.25 H=0.3866 L=1.6413 M=1.6413 N=1.2731 (as used in this test)
# Substituting the values of stress components and F, G, H, L, M and N we obtain
# q = 15.9568 Pa
#
# Equivalent_creep_strain_rate = A(q)^n (power law creep rate used in this test)
# Substituting A=1e-16 and n=9, and q as calculated above, we obtain
# Equivalent_creep_strain_rate = 6.7068e-06
#
# The 12 (xy) component of creep_strain_tensor is calculated as below
# creep_strain_tensor_12 = (Equivalent_creep_strain_rate / q) * 2.0 * N * S12 * time_increment
# Substituting the values and time_increment as 0.001 we obtain the analytical solution.

# 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

# 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.

# 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

# Basic example coupling a master and sub app in a 3D cylindrical mesh from an input file

# The master app provides field values to the sub app via Functional Expansions, which then performs
# its calculations. The sub app's solution field values are then transferred back to the master app
# and coupled into the solution of the master app solution.
#
# This example couples Functional Expansions via AuxVariable, the recommended approach.

# 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

# 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

# This test simulates uniaxial tensile loading in y-direction.
# The slope of the stress vs. plastic strain is evaluated from
# the simulation and compared with the value calculated using
# the analytical expression. This test uses a material with li-
# near strain hardening.
# For uniaxial tensile loading in y-direction, the slope of the
# stress vs. plastic strain is (2K / (F + H)) where K is the ha-
# rdening constant, and F & H are the Hill's constant. For deta-
# ils on the derivation of the expression for slope please refer
# the documentation of this material.
# Slope obtained from this MOOSE test simulation:
# = 1.521 x 10^9
# Slope obtained from analytical expression:
# = 2 x 10^9 / (0.6 + 0.7) = 1.538 x 10^9

# 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.

# q = [F(S22-S33)^2 + G(S33-S11)^2 + H(S11-S22)^2 + 2L(S23)^2 + 2M(S13)^2 + 2N(S12)^2]^0.5
# S11 = 40 Pa; other compoenents of stress are zero since it is a uniaxial test
# F=0.5 G=0.25 H=0.3866 L=1.6413 M=1.6413 N=1.2731 (as used in this test)
# Substituting the values of stress components and F, G, H, L, M and N we obtain
# q = 31.9148868 Pa
#
# Equivalent_creep_strain_rate = A(q)^n (power law creep rate used in this test)
# Substituting A=1e-16 and n=9, and q as calculated above, we obtain
# Equivalent_creep_strain_rate = 3.4351030990356175e-07
#
# The 11 (xx) component of creep_strain_tensor is calculated as below
# creep_strain_tensor_11 = (Equivalent_creep_strain_rate / q) *
# (H * (S11 - S22) - G * (S33 - S11)) * time_increment
# Substituting the values and time_increment as 0.001 we obtain the analytical solution.

# 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 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

# This test simulates uniaxial tensile loading in x-direction.
# The slope of the stress vs. plastic strain is evaluated from
# the simulation and compared with the value calculated using
# the analytical expression. This test uses a material with li-
# near strain hardening.
# For uniaxial tensile loading in y-direction, the slope of the
# stress vs. plastic strain is (2K / (G + H)) where K is the ha-
# rdening constant, and G & H are the Hill's constant. For deta-
# ils on the derivation of the expression for slope please refer
# the documentation of this material.
# Slope obtained from this MOOSE test simulation:
# = 1.791 x 10^9
# Slope obtained from analytical expression:
# = 2 x 10^9 / (0.4 + 0.7) = 1.818 x 10^9

#
# 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.

# Basic example coupling a master and sub app in a 3D Cartesian volume.
#
# The master app provides field values to the sub app via Functional Expansions, which then performs
# its calculations. The sub app's solution field values are then transferred back to the master app
# and coupled into the solution of the master app solution.
#
# This example couples Functional Expansions via AuxVariable.
#
# Note: this problem is not light, and may take a few minutes to solve.

# 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

# q = [F(S22-S33)^2 + G(S33-S11)^2 + H(S11-S22)^2 + 2L(S23)^2 + 2M(S13)^2 + 2N(S12)^2]^0.5

# F=0.5 G=0.25 H=0.3866 L=1.6413 M=1.6413 N=1.2731 (as used in this test)
# Substituting the values of stress components and F, G, H, L, M and N we obtain
# q = 34.64101615137755 Pa
#
# Equivalent_creep_strain_rate = A(q)^n (power law creep rate used in this test)
# Substituting A=1e-15 and n=9, and q as calculated above, we obtain
# Equivalent_creep_strain_rate = 0.07183161109149655
#
# The 11 (xx) and 22 (yy) components of creep_strain_tensor are calculated as below:
#
# creep_strain_tensor_11 = (Equivalent_creep_strain_rate / q) *
# (H * (S11 - S22) - G * (S33 - S11)) * time_increment
# creep_strain_tensor_22 = (Equivalent_creep_strain_rate / q) *
# (F * (S22 - S33) - H * (S11 - S22)) * time_increment
#
# Substituting the values and time_increment as 0.001 we obtain the analytical solution.
