# Test cases for convective boundary conditions.
# Input file for htc_3dtest0
# TKLarson
# 11/02/11
# Revision 0
#
# Goals of this test are:
# 1) show that the 'fluid' temperature for convective boundary condition
# is behaving as expected/desired
# 2) show that expected results ensue from application of convective boundary conditions
# Convective boundary condition:
# q = h*A*(Tw - Tf)
# where
# q - heat transfer rate (w)
# h - heat transfer coefficient (w/m^2-K)
# A - surface area (m^2)
# Tw - surface temperature (K)
# Tf - fluid temperature adjacent to the surface (K)
# The heat transfer coefficient (h) is input as a variable called 'rate'
# Tf is a two valued function specified by 'initial' and 'final' along with a variable
# called 'duration,' the length of time in seconds that it takes initial to linearly ramp
# to 'final.'
# The mesh for this test case is concocted from an ASTM standard for the so-called Brazillian Cylinder test
# (ASTM International, Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete
# Specimens, C 496/C 496M-04, 2004). I turned a cylinder model into a rectangular parallelpiped,
# because I already had the cylinder model.
# The model is 3-d xyz coordinates.
#
# Brazillian Parallelpiped sample dimensions:
# z = 10.3 cm, 0.103 m, (4 in)
# y = 5.08 cm, 0.0508 m, (2 in)
# x = 5.08 cm, 0.0508 m, (2 in)
# Material properties are:
# density = 2405.28 km/m^3
# specific heat = 826.4 J/kg-K
# thermal conductivity 1.937 w/m-K
# alpha (thermal conductivity/(density*specific heat) is then 9.74e-7 m^2/s
#
# Initial parallelpiped temperature is room temperature 294.26 K (70 F)
# The initial fluid temperature is room temperature. We will ramp it to 477.6 K (400 F) in 10 minutes.
# We will use a very large h (1000000) to make the surface temperature mimick the fluid temperature.
# What we expect for this problem:
# 1) Use of h = 1000000 should cause the parallelpiped surface temperature to track the fluid temperature
# 2) The fluid temperature should rise from initial (294.26 K) to final (477.6 K) in 600 s.
# 3) 1) and 2) should prove that the Tf boundary condition is ramping as desired.
# Note, we do the above because there is no way to plot a variable that is not on a mesh node!

# 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.

# Test cases for convective boundary conditions. TKLarson, 11/01/11, rev. 0.
# Input file for htc_2dtest1
# TKLarson
# 11/01/11
# Revision 0
#
# Goals of this test are:
# 1) show that expected results ensue from application of convective boundary conditions
# Convective boundary condition:
# q = h*A*(Tw - Tf)
# where
# q - heat transfer rate (w)
# h - heat transfer coefficient (w/m^2-K)
# A - surface area (m^2)
# Tw - surface temperature (K)
# Tf - fluid temperature adjacent to the surface (K)
# The heat transfer coefficient (h) is input as a variable called 'rate'
# Tf is a two valued function specified by 'initial' and 'final' along with a variable
# called 'duration,' the length of time in seconds that it takes initial to linearly ramp
# to 'final.'
# The mesh for this test case is based on an ASTM standard for the so-called Brazillian Cylinder test
# (ASTM International, Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete
# Specimens, C 496/C 496M-04, 2004) (because I already had a version of the model). While the
# Brazillian Cylinder test is for dynamic tensile testing of concrete, the model works for the present
# purposes. The model is 2-d RZ coordinates.
#
# Brazillian Cylinder sample dimensions:
# L = 20.3 cm, 0.203 m, (8 in)
# r = 5.08 cm, 0.0508 m, (2 in)
# Material properties are:
# density = 2405.28 km/m^3
# specific heat = 826.4 J/kg-K
# thermal conductivity 1.937 w/m-K
# alpha (thermal conductivity/(density*specific heat) is then 9.74e-7 m^2/s
#
# Initial cylinder temperature is room temperature 294.26 K (70 F)
# The initial fluid temperature is room temperature. We will ramp it to 477.6 K (400 F) in 10 minutes.
# We will use a natural convection h (284 w/m^2-K (50 BTU/hr-ft^2-F)) on all faces of the cylinder.
# This is akin to putting the cylinder in an oven (nonconvection type) and turning the oven on.
# What we expect for this problem:
# 1) Use of h = 284 should cause the cylinder to slowly warm up
# 2) The fluid temperature should rise from initial (294 K) to final (477 K) in 600 s.
# 3) 1) and 2) should cause the cylinder to become soaked at 477.6 K after sufficient time(i.e. ~ 1/2 hr).
# This is a simple thermal soak problem.

# Test cases for convective boundary conditions. TKLarson, 11/01/11, rev. 0.
# Input file for htc_2dtest0
# TKLarson
# 11/01/11
# Revision 0
#
# Goals of this test are:
# 1) show that the 'fluid' temperature for convective boundary condition
# is behaving as expected/desired
# 2) show that expected results ensue from application of convective boundary conditions
# Convective boundary condition:
# q = h*A*(Tw - Tf)
# where
# q - heat transfer rate (w)
# h - heat transfer coefficient (w/m^2-K)
# A - surface area (m^2)
# Tw - surface temperature (K)
# Tf - fluid temperature adjacent to the surface (K)
# The heat transfer coefficient (h) is input as a variable called 'rate'
# Tf is a two valued function specified by 'initial' and 'final' along with a variable
# called 'duration,' the length of time in seconds that it takes initial to linearly ramp
# to 'final.'
# The mesh for this test case is based on an ASTM standard for the so-called Brazillian Cylinder test
# (ASTM International, Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete
# Specimens, C 496/C 496M-04, 2004) (because I already had a version of the model). While the
# Brazillian Cylinder test is for dynamic tensile testing of concrete, the model works for the present
# purposes. The model is 2-d RZ coordinates.
#
# Brazillian Cylinder sample dimensions:
# L = 20.3 cm, 0.203 m, (8 in)
# r = 5.08 cm, 0.0508 m, (2 in)
# Material properties are:
# density = 2405.28 km/m^3
# specific heat = 826.4 J/kg-K
# thermal conductivity 1.937 w/m-K
# alpha (thermal conductivity/(density*specific heat) is then 9.74e-7 m^2/s
#
# Initial cylinder temperature is room temperature 294.26 K (70 F)
# The initial fluid temperature is room temperature. We will ramp it to 477.6 K (400 F) in 10 minutes.
# We will use a very large h (1000000) to make the surface temperature mimick the fluid temperature.
# What we expect for this problem:
# 1) Use of h = 1000000 should cause the cylinder surface temperature to track the fluid temperature
# 2) The fluid temperature should rise from initial (294.26 K) to final (477.6 K) in 600 s.
# 3) 1) and 2) should prove that the Tf boundary condition is ramping as desired.
# Note, we do the above because there is no way to plot a variable that is not on a mesh node!

# Test cases for convective boundary conditions.
# Input file for htc_3dtest1
# TKLarson
# 11/02/11
# Revision 0
#
# Goals of this test are:
# 1) show that the 'fluid' temperature for convective boundary condition
# is behaving as expected/desired
# 2) show that expected results ensue from application of convective boundary conditions
# Convective boundary condition:
# q = h*A*(Tw - Tf)
# where
# q - heat transfer rate (w)
# h - heat transfer coefficient (w/m^2-K)
# A - surface area (m^2)
# Tw - surface temperature (K)
# Tf - fluid temperature adjacent to the surface (K)
# The heat transfer coefficient (h) is input as a variable called 'rate'
# Tf is a two valued function specified by 'initial' and 'final' along with a variable
# called 'duration,' the length of time in seconds that it takes initial to linearly ramp
# to 'final.'
# The mesh for this test case is concocted from an ASTM standard for the so-called Brazillian Cylinder test
# (ASTM International, Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete
# Specimens, C 496/C 496M-04, 2004). I turned a cylinder model into a rectangular parallelpiped,
# because I already had the cylinder model.
# The model is 3-d xyz coordinates.
#
# Brazillian Parallelpiped sample dimensions:
# z = 10.3 cm, 0.103 m, (4 in)
# y = 5.08 cm, 0.0508 m, (2 in)
# x = 5.08 cm, 0.0508 m, (2 in)
# Material properties are:
# density = 2405.28 km/m^3
# specific heat = 826.4 J/kg-K
# thermal conductivity 1.937 w/m-K
# alpha (thermal conductivity/(density*specific heat) is then 9.74e-7 m^2/s
#
# Initial parallelpiped temperature is room temperature 294.26 K (70 F)
# The initial fluid temperature is room temperature. We will ramp it to 477.6 K (400 F) in 10 minutes.
# We will use an h representative of natural convection conditions as the boundary condition for all sides
# on the parallelpiped. Akin to putting the object in an oven and turning the oven on.
# This is essentially a thermal soak.
#
# What we expect for this problem:
# 1) Use of h = 284 w/m^2-K (50 BTU/hr-ft^2-F) should cause the parallelpiped to slowly heat up to 477K.
# 2) The fluid temperature should rise from initial (294.26 K) to final (477.6 K) in 600 s.
# 3) 1) and 2) should show the convective BC is working as desired.

#
# Simple power law creep example (without instantaneous plasticity)
# NOTE: this test is not replicated in a direct tensor mechanics form because the functioning
# of the individual TM power law creep and TM isotropic plasticity is already tested in the
# tensor mechanics module.
#
# The mesh is a 1x1x1 cube with a constant pressure of 10 MPa on the top face.
# Symmetry boundary conditions on three planes provide a uniaxial stress
# field. The temperature is held constant at 1000. The yield stress is set
# at twice the load pressure, thus there is no plasticity. The solution is
# advanced through ten time steps of 0.1 for a total time of 1.
#
# The total strain at time 1 can be computed as:
#
# e_tot = e_elas + e_creep
#
# = P/E + A * sigma**n * exp(-Q/(RT)) * t**m * dt
#
# where P = pressure load
# E = Young's modulus
# A = material parameter
# sigma = stress
# n = power law exponent
# Q = activation energy
# R = gas constant
# T = temperature
# t = time
# m = time hardening exponent
# dt = problem time
#
# For this test, the analytical solutuon is:
#
# e_tot = (10e6/2e11) + 1e-15 * (10e6)**4 * exp(-3e5/(8.3143*1000) * t**0 * 1
# = 5e-5 + 2.136031e-3
# = 2.186031e-3
#
#
# For either linear (formulation = linear) or nonlinear (formulation = nonlinear3d)
# kinematics, PLC_LSH gets:
#
# e_elas = 5e-5
# e_creep = 2.13600e-3
# e_tot = 2.18600e-3

modules/combined/test/tests/power_law_creep/creep_only_combined_class_sm1.i
#
# Simple power law creep example (without instantaneous plasticity).
# NOTE: this test is not replicated in a direct tensor mechanics form because the functioning
# of the individual TM power law creep and TM isotropic plasticity is already tested in the
# tensor mechanics module.
#
# The mesh is a 1x1x1 cube with a constant pressure of 10 MPa on the top face.
# Symmetry boundary conditions on three planes provide a uniaxial stress
# field. The temperature is held constant at 1000. The yield stress is set
# at twice the load pressure, thus there is no plasticity. The solution is
# advanced through ten time steps of 0.1 for a total time of 1.
#
# The total strain at time 1 can be computed as:
#
# e_tot = e_elas + e_creep
#
# = P/E + A * sigma**n * exp(-Q/(RT)) * t**m * dt
#
# where P = pressure load
# E = Young's modulus
# A = material parameter
# sigma = stress
# n = power law exponent
# Q = activation energy
# R = gas constant
# T = temperature
# t = time
# m = time hardening exponent
# dt = problem time
#
# For this test, the analytical solutuon is:
#
# e_tot = (10e6/2e11) + 1e-15 * (10e6)**4 * exp(-3e5/(8.3143*1000) * t**0 * 1
# = 5e-5 + 2.136031e-3
# = 2.186031e-3
#
#
# For either linear (formulation = linear) or nonlinear (formulation = nonlinear3d)
# kinematics, PLC_LSH gets:
#
# e_elas = 5e-5
# e_creep = 2.13600e-3
# e_tot = 2.18600e-3
#
