ElementalVariableValue
Outputs an elemental variable value at a particular location
Description
In some cases it may be of interest to output an elemental variable value (e.g., stress) at a particular location in the model. This is accomplished by using the ElementalVariableValue postprocessor. This postprocessor takes a specific element ID to sample (only a single ID). The value of the specified variable is integrated over the element and then returned.
Example Input Syntax

# 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

# Slope obtained from this MOOSE test simulation:

# Results have been compared for various thicknesses with the following approximate Results

# Thickness = 0.1. Reference freq: 10.785 Hz, Moose freq: 10.612 Hz
# Thickness = 0.05. Reference freq: 5.393 Hz, Moose freq: 5.335 Hz

#
# Reference values have been obtained from Robert Blevins, "Formulas for Dynamics, Acoustics and Vibration",
# Table 5.3 case 11. Formula looks like: f = lambda^2/(2*pi*a^2) * sqrt(E*h^2/(12*(1-nu*nu))), where lambda
# changes as a function of shell dimensions.

# This test 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.

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

# This test 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 test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# hardening curve capability.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

# 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

# Tests the initial condition for mixture density from pressure and temperature.
# This test uses the general vapor mixture fluid properties with steam, air,
# and helium with mass fractions 0.5, 0.3, and 0.2, respectively. The individual
# specific volumes (in m^3/kg) at p = 100 kPa, T = 500 K are:
# steam: 2.298113001
# air: 1.43525
# helium: 10.3855
# For the general vapor mixture, the mixture specific volume is computed as
# v = \sum\limits_i x_i v_i ,
# where x_i is the mass fraction of component i, and v_i is the specific volume
# of component i. Therefore, the correct value for specific volume of the mixture is
# v = 3.65673150050 m^3/kg
# and thus density is
# rho = 0.27346825980066236 kg/m^3

# 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.

# Test that models bending of a rotated cantilever beam using shell elements
# A cantilever beam of length 10 m (in Z direction) and cross-section
# 1 m x 0.1 m is modeled using 4 shell elements placed along the length
# (Figure 6a from Dvorkin and Bathe, 1984). All displacements and
# X rotations are fixed on the bottom boundary. E = 2100000 and v = 0.0.
# A load of 0.5 N (in the Y direction) is applied at each node on the top
# boundary resulting in a total load of 1 N.
# The analytical solution for displacement at tip using small strain/rotations # is PL^3/3EI + PL/AG = 1.90485714 m
# The FEM solution using 4 shell elements is 1.875095 m with a relative error
# of 1.5%.
# Similarly, the analytical solution for slope at tip is PL^2/2EI = 0.285714286
# The FEM solution is 0.2857143 and the relative error is 5e-6%.
# The stress_zz for the four elements at y = -0.57735 * (t/2) (first qp below mid-surface of shell) are:
# 3031.089 Pa, 2165.064 Pa, 1299.038 Pa and 433.0127 Pa.
# Note the above values are the average stresses in each element.
# Analytically, stress_zz decreases linearly from z = 0 to z = 10 m.
# The maximum value of stress_zz at z = 0 is My/I = PL * 0.57735*(t/2)/I = 3464.1 Pa
# Therefore, the analytical value of stress at y = -0.57735 * (t/2) at the mid-point
# of the four elements are:
# 3031.0875 Pa, 2165.0625 Pa, 1299.0375 Pa ,433.0125 Pa
# The relative error in stress_zz is in the order of 5e-5%.
# The stress_yz at y = -0.57735 * (t/2) at all four elements from the simulation is 10 Pa.
# The analytical solution for the shear stress is: V/2/I *((t^2)/4 - y^2), where the shear force (V)
# is 1 N at any z along the length of the beam. Therefore, the analytical shear stress at
# y = -0.57735 * (t/2) is 10 Pa at any location along the length of the beam.

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

# Affine Plasticity Test for Transient Stress Eigenvalues with Stationary Eigenvectors
# This test is taken from K. Jamojjala, R. Brannon, A. Sadeghirad, J. Guilkey,
# "Verification tests in solid mechanics," Engineering with Computers, Vol 31.,
# p. 193-213.
# The test involves applying particular strains and expecting particular stresses.
# The material properties are:
# Yield in shear 165 MPa
# Shear modulus 79 GPa
# Poisson's ratio 1/3
# The strains are:
# Time e11 e22 e33
# 0 0 0 0
# 1 -0.003 -0.003 0.006
# 2 -0.0103923 0 0.0103923
# The expected stresses are:
# sigma11:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# (189.4+0.1704*sqrt(a)-0.003242*a)
# --------------------------------- 1 < t <= 2
# 1+0.00001712*a
# -189.4 t > 2 (paper erroneously gives a positive value)
#
# sigma22:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# -(76.87+1.443*sqrt(a)-0.001316*a)
# --------------------------------- 1 < t <= 2 (paper gives opposite sign)
# 1+0.00001712*a
# 76.87 t > 2
#
# sigma33:
# 948*t 0 < t <= 0.201
# 190.5 0.201 < t <= 1
# -(112.5-1.272*sqrt(a)-0.001926*a)
# --------------------------------- 1 < t <= 2 (paper has two sign errors here)
# 1+0.00001712*a
# 112.5 t > 2
#
# where a = exp(12.33*t).
#
# Note: If planning to run this case with strain type ComputeFiniteStrain, the
# displacement function must be adjusted. Instead of
# strain = (l - l0)/l0 = (u+l0 - l0)/l0 = u/l0
# with l0=1.0, we would have
# strain = log(l/l0) = log((u+l0)/l0)
# with l0=1.0. So, for strain = -0.003,
# -0.003 = log((u+l0)/l0) ->
# u = exp(-0.003)*l0 - l0 = -0.0029955044966269995.

# 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.

# Test that models bending of a cantilever beam using shell elements
# A cantilever beam of length 10 m (in Y direction) and cross-section
# 1 m x 0.1 m is modeled using 4 shell elements placed along the length
# (Figure 6a from Dvorkin and Bathe, 1984). All displacements and
# X rotations are fixed on the bottom boundary. E = 2100000 and v = 0.0.
# A load of 0.5 N (in the Z direction) is applied at each node on the top
# boundary resulting in a total load of 1 N.
# The analytical solution for displacement at tip using small strain/rotations # is PL^3/3EI + PL/AG = 1.90485714 m
# The FEM solution using 4 shell elements is 1.875095 m with a relative error
# of 1.5%.
# Similarly, the analytical solution for slope at tip is PL^2/2EI = 0.285714286
# The FEM solution is 0.2857143 and the relative error is 5e-6%.
# The stress_yy for the four elements at z = -0.57735 * (t/2) (first qp below mid-surface of shell) are:
# 3031.089 Pa, 2165.064 Pa, 1299.038 Pa and 433.0127 Pa.
# Note the above values are the average stresses in each element.
# Analytically, stress_yy decreases linearly from y = 0 to y = 10 m.
# The maximum value of stress_yy at y = 0 is Mz/I = PL * 0.57735*(t/2)/I = 3464.1 Pa
# Therefore, the analytical value of stress at z = -0.57735 * (t/2) at the mid-point
# of the four elements are:
# 3031.0875 Pa, 2165.0625 Pa, 1299.0375 Pa ,433.0125 Pa
# The relative error in stress_yy is in the order of 5e-5%.
# The stress_yz at z = -0.57735 * (t/2) at all four elements from the simulation is 10 Pa.
# The analytical solution for the shear stress is: V/2/I *((t^2)/4 - z^2), where the shear force (V)
# is 1 N at any y along the length of the beam. Therefore, the analytical shear stress at
# z = -0.57735 * (t/2) is 10 Pa at any location along the length of the beam.

#
# This is a test of the piece-wise linear strain hardening model using the
# small strain formulation. This test exercises the temperature-dependent
# hardening curve capability.
#
# Test procedure:
# 1. The element is pulled to and then beyond the yield stress for a given
# temperature.
# 2. The displacement is then constant while the temperature increases and
# the yield stress decreases. This results in a lower stress with more
# plastic strain.
# 3. The temperature decreases beyond its original value giving a higher
# yield stress. The displacement increases, causing increases stress to
# the new yield stress.
# 4. The temperature and yield stress are constant with increasing
# displacement giving a constant stress and more plastic strain.
#
# Plotting total_strain_yy on the x axis and stress_yy on the y axis shows
# the stress history in a clear way.

# Test that models bending of a cantilever beam using shell elements
# A cantilever beam of length 10 m (in Y direction) and cross-section
# 1 m x 0.1 m is modeled using 4 shell elements placed along the length
# (Figure 6a from Dvorkin and Bathe, 1984). All displacements and
# X rotations are fixed on the bottom boundary. E = 2100000 and v = 0.0.
# A load of 0.5 N (in the Z direction) is applied at each node on the top
# boundary resulting in a total load of 1 N.
# The analytical solution for displacement at tip using small strain/rotations # is PL^3/3EI + PL/AG = 1.90485714 m
# The FEM solution using 4 shell elements is 1.875095 m with a relative error
# of 1.5%.
# Similarly, the analytical solution for slope at tip is PL^2/2EI = 0.285714286
# The FEM solution is 0.2857143 and the relative error is 5e-6%.
# The stress_yy for the four elements at z = -0.57735 * (t/2) (first qp below mid-surface of shell) are:
# 3031.089 Pa, 2165.064 Pa, 1299.038 Pa and 433.0127 Pa.
# Note the above values are the average stresses in each element.
# Analytically, stress_yy decreases linearly from y = 0 to y = 10 m.
# The maximum value of stress_yy at y = 0 is Mz/I = PL * 0.57735*(t/2)/I = 3464.1 Pa
# Therefore, the analytical value of stress at z = -0.57735 * (t/2) at the mid-point
# of the four elements are:
# 3031.0875 Pa, 2165.0625 Pa, 1299.0375 Pa ,433.0125 Pa
# The relative error in stress_yy is in the order of 5e-5%.
# The stress_yz at z = -0.57735 * (t/2) at all four elements from the simulation is 10 Pa.
# The analytical solution for the shear stress is: V/2/I *((t^2)/4 - z^2), where the shear force (V)
# is 1 N at any y along the length of the beam. Therefore, the analytical shear stress at
# z = -0.57735 * (t/2) is 10 Pa at any location along the length of the beam.

# Affine Plasticity Test for Transient Stress Eigenvalues with Stationary Eigenvectors
# This test is taken from K. Jamojjala, R. Brannon, A. Sadeghirad, J. Guilkey,
# "Verification tests in solid mechanics," Engineering with Computers, Vol 31.,
# p. 193-213.
# The test involves applying particular strains and expecting particular stresses.
# The material properties are:
# Yield in shear 165 MPa
# Shear modulus 79 GPa
# Poisson's ratio 1/3
# The strains are:
# Time e11 e22 e33
# 0 0 0 0
# 1 -0.003 -0.003 0.006
# 2 -0.0103923 0 0.0103923
# The expected stresses are:
# sigma11:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# (189.4+0.1704*sqrt(a)-0.003242*a)
# --------------------------------- 1 < t <= 2
# 1+0.00001712*a
# -189.4 t > 2 (paper erroneously gives a positive value)
#
# sigma22:
# -474*t 0 < t <= 0.201
# -95.26 0.201 < t <= 1
# -(76.87+1.443*sqrt(a)-0.001316*a)
# --------------------------------- 1 < t <= 2 (paper gives opposite sign)
# 1+0.00001712*a
# 76.87 t > 2
#
# sigma33:
# 948*t 0 < t <= 0.201
# 190.5 0.201 < t <= 1
# -(112.5-1.272*sqrt(a)-0.001926*a)
# --------------------------------- 1 < t <= 2 (paper has two sign errors here)
# 1+0.00001712*a
# 112.5 t > 2
#
# where a = exp(12.33*t).
#
# Note: If planning to run this case with strain type ComputeFiniteStrain, the
# displacement function must be adjusted. Instead of
# strain = (l - l0)/l0 = (u+l0 - l0)/l0 = u/l0
# with l0=1.0, we would have
# strain = log(l/l0) = log((u+l0)/l0)
# with l0=1.0. So, for strain = -0.003,
# -0.003 = log((u+l0)/l0) ->
# u = exp(-0.003)*l0 - l0 = -0.0029955044966269995.

# 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.

# This tests the ability of the ADComputeVolumetricEigenstrain material
# to compute an eigenstrain tensor that results in a solution that exactly
# recovers the specified volumetric expansion.
# This model applies volumetric strain that ramps from 0 to 2 to a unit cube
# and computes the final volume, which should be exactly 3. Note that the default
# TaylorExpansion option for decomposition_method gives a small (~4%) error
# with this very large incremental strain, but decomposition_method=EigenSolution
# gives the exact solution.
