GenericFunctionMaterial
Material object for declaring properties that are populated by evaluation of Function object.
This can be used to quickly create simple functionalized material properties, for testing, for initial survey of a problem or simply because the material properties do not vary much from the defined function over the domain explored by the simulation.
Example Input File Syntax
In this example, GenericFunctionMaterial
is used to define a diffusion coefficient that is inversely proportional to time. The diffusion coefficient is retrieved as a MaterialProperty
by the diffusion kernel.

# 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.

# XFEM Moving Interface Verification Problem
# Dimensionality: quasi-1D
# Coordinate System: rz
# Material Numbers/Types: level set dep 1 material, 2 region
# Element Order: 1st
# Interface Characteristics: u independent, prescribed level set function
# Description:
# A simple transient heat transfer problem in cylindrical coordinates designed
# with the Method of Manufactured Solutions. This problem was developed to
# verify XFEM performance in the presence of a moving interface for linear
# element models that can be exactly evaluated by FEM/Moose. Both the
# temperature solution and level set function are designed to be linear to
# attempt to minimize error between the Moose/exact solution and XFEM results.
# Thermal conductivity is dependent upon the value of the level set function
# at each timestep.
# Results:
# The temperature at the left boundary (x=1) exhibits the largest difference
# between the FEM/Moose solution and XFEM results. We present the XFEM
# results at this location with 10 digits of precision:
# Time Expected Temperature XFEM Calculated Temperature
# 0.2 440 440
# 0.4 480 480.0008131
# 0.6 520 520.0038333

# 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.

# 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

# This is a basic test of the system for continuum damage mechanics

# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies

# XFEM Moving Interface Verification Problem
# Dimensionality: 2D
# Coordinate System: xy
# Material Numbers/Types: level set dep 1 material, 2 region
# Element Order: 1st
# Interface Characteristics: u independent, prescribed level set function
# Description:
# Transient 2D heat transfer problem in Cartesian coordinates designed with
# the Method of Manufactured Solutions. This problem was developed to verify
# XFEM performance on linear elements in the presence of a moving interface
# sweeping across the x-y coordinates of a system with thermal conductivity
# dependent upon the transient level set function. This problem can be
# exactly evaluated by FEM/Moose without the moving interface. Both the
# temperature and level set function are designed to be linear to attempt to
# minimize the error between the Moose/exact solution and XFEM results.
# Results:
# The temperature at the bottom left boundary (x=0, y=0) exhibits the largest
# difference between the FEM/Moose solution and XFEM results. We present the
# XFEM results at this location with 10 digits of precision:
# Time Expected Temperature XFEM Calculated Temperature
# 0.2 440 440
# 0.4 480 479.9998738

# This test compares the hoop strain at two different elements in an internally
# pressurized cylinder with anisotropic plasticity: different yield condition
# for hoop and axial directions. The elements are located circumferentially
# apart but at same axial position. It is expected that due to pressurization
# hoop strains will develop with uniform magnitude along hoop direction. The
# test verifies that the plastic hoop strain is uniform in hoop direction.
# For 3D simulations with material properties oriented along the curved
# geometry such as cylinder or sphere, the stresses and strains are rotated to
# the local coordinate system from the global coordinate system. The plastic
# strain is calculated in the local coordinate system and then transformed to
# the global coordinate system. This test involves a 3D cylindrical geometry,
# and helps in indirectly verifying that this transformation of stresses and
# strains back and forth between the local and global coordinate system is
# correctly implemented.

# 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.

# 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
# 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

# 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

# XFEM Moving Interface Verification Problem
# Dimensionality: quasi-1D
# Coordinate System: xy
# Material Numbers/Types: level set dep 1 material, 2 region
# Element Order: 1st
# Interface Characteristics: u independent, prescribed level set function
# Description:
# A simple transient heat transfer problem in Cartesian coordinates designed
# with the Method of Manufactured Solutions. This problem was developed to
# verify XFEM performance in the presence of a moving interface for linear
# element models that can be exactly evaluated by FEM/Moose. Both the
# temperature solution and level set function are designed to be linear to
# attempt to minimize error between the Moose/exact solution and XFEM results.
# Thermal conductivity is dependent upon the value of the level set function
# at each timestep.
# Results:
# The temperature at the left boundary (x=0) exhibits the largest difference
# between the FEM/Moose solution and XFEM results. We present the XFEM
# results at this location with 10 digits of precision:
# Time Expected Temperature XFEM Calculated Temperature
# 0.2 440 440
# 0.4 480 479.9999722
# 0.6 520 519.9998726
# 0.8 560 559.9997314

# 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

# XFEM Moving Interface Verification Problem
# Dimensionality: 2D
# Coordinate System: rz
# Material Numbers/Types: level set dep 1 material, 2 region
# Element Order: 1st
# Interface Characteristics: u independent, prescribed level set function
# Description:
# Transient 2D heat transfer problem in cylindrical coordinates designed with
# the Method of Manufactured Solutions. This problem was developed to verify
# XFEM performance on linear elements in the presence of a moving interface
# sweeping across the x-y coordinates of a system with thermal conductivity
# dependent upon the transient level set function. This problem can be
# exactly evaluated by FEM/Moose without the moving interface. Both the
# temperature and level set function are designed to be linear to attempt to
# minimize the error between the Moose/exact solution and XFEM results.
# Results:
# The temperature at the bottom left boundary (x=1, y=1) exhibits the largest
# difference between the FEM/Moose solution and XFEM results. We present the
# XFEM results at this location with 10 digits of precision:
# Time Expected Temperature XFEM Calculated Temperature
# 0.2 440 440
# 0.4 480 479.9998717
# 0.6 520 519.9994963
