# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks in the x-z plane. Each element block
# is a square. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far bottom boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far top
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
# The heat flux across the gap at time = 1 is then:
#
# Flux = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors. These results
# are the same as for the unit 1-D gap heat transfer between two unit cubes.

#
# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a helium-filled gap including radiation.
#
# The mesh consists of two element blocks containing one element each. Each
# element is a unit cube. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * h_gap
#
# where h_gap = h_gas + h_cont + h_rad
#
# By setting the contact pressure, roughnesses, and jump distances to zero, the gap
# conductance simplifies to:
#
# h_gap = gapK/d_gap + sigma*Fe*(T_left^2 + T_right^2)*(T_left + T_right)
#
# where Fe = 1/(1/eps_left + 1/eps_right - 1)
# eps = emissivity
#
# For pure helium, BISON computes the gas conductivity as:
#
# gapK(Tavg) = 2.639e-3*Tavg^0.7085
#
# For the test, the final (t=2) average gas temperature is (200 +100)/2 = 150,
# giving gapK(150) = 0.09187557
#
# Assuming ems_left = ems_right = 0.5, Fe = 1/3
#
# The heat flux across the gap at that time is then:
#
# Flux(2) = 100 * ((0.09187557/1.0) + (5.669e-8/3)*(200^2 + 100^2)*(200 + 100))
# = 37.532557
#
# The flux post processors give 37.53255

# This problem is modified from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
# The original stress solution is given as:
# xx = yy = zz = 2000
# xy = 400
#
# Here, E=1e6 and nu=0.25.
# However, with a +100 degree change in temperature and a coefficient
# of thermal expansion of 1e-6, the solution becomes:
# xx = yy = zz = 1800
# xy = 400
# since
# E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800
#
# Also,
#
# dSrr dSrz Srr-Stt
# ---- + ---- + ------- + br = 0
# dr dz r
#
# and
#
# dSrz Srz dSzz
# ---- + --- + ---- + bz = 0
# dr r dz
#
# where
# Srr = stress in rr
# Szz = stress in zz
# Stt = stress in theta-theta
# Srz = stress in rz
# br = body force in r direction
# bz = body force in z direction
#
# This test is meant to exercise the Jacobian. To that end, the body
# force has been turned off. This makes the results differ slightly
# from the original values, but requires a correct Jacobian for minimal
# iterations. Iteration plotting is turned on to ensure that the
# number of iterations needed does not increase.

# Gravity Test
#
# This test is designed to exercise the gravity body force kernel.
#
# The mesh for this problem is a rectangular bar 10 units by 1 unit
# by 1 unit.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at x=0. The stress
# is reported at element centers. The element closest to x=0 sits
# at x = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at x = L where the stress is zero analytically. The nearest
# element is at x=9.75 where the stress is 10.

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks containing one element each. Each
# element is a unit cube. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
#
# The heat flux across the gap at time = 2 is then:
#
# Flux(2) = 100 * (1.0/1.0) = 100

# 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.

# Deprecated: large_strain = true only introduces high order terms in the strain calculation
# but no rotation has been considered in solid mechanics. No such corresponding strain calculator
# in tensor mechanics
#
#
# This problem is adapted from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
#
# For large strain,
# e_rr = 1e-3 + (1e-3)^2
# e_zz = 1e-3 + 0.5*(1e-3)^2
# e_tt = 1e-3 + 0.5*(1e-3)^2
# e_rz = 0.5*(1e-3+(1e-3)^2)
#
# If you multiply these strains through the elasticity tensor for
# axisymmetry, you will obtain the following stresses:
# xx = 2001.6
# yy = zz = 2001.2
# xy = 400.4

# Patch Test
# This test is designed to compute constant xx, yy, zz, xy, yz, and zx
# 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.
# 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
# However, we must also consider the thermal strain.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-8. Therefore, the thermal strain (and the displacement
# since this is a unit cube) is 1e-6.
# Therefore, the overall effect is (at time 1, with a 50 degree delta):
#
# stress xx = 1e6 * (1e-6-0.5e-6) = 0.5
# stress yy = 1e6 * (2e-6-0.5e-6) = 1.5
# stress zz = 1e6 * (3e-6-0.5e-6) = 2.5
# 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
#
# At time 2:
#
# stress xx = 1e6 * (1e-6-1e-6) = 0
# stress yy = 1e6 * (2e-6-1e-6) = 1
# stress zz = 1e6 * (3e-6-1e-6) = 2
# 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

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks in the y-z plane. Each element block
# is a square. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far bottom boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far top
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
# The heat flux across the gap at time = 1 is then:
#
# Flux = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors. These results
# are the same as for the unit 1-D gap heat transfer between two unit cubes.

# This problem is modified from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
# The original stress solution is given as:
# xx = yy = zz = 2000
# xy = 400
#
# Here, E=1e6 and nu=0.25.
# However, with a +100 degree change in temperature and a coefficient
# of thermal expansion of 1e-6, the solution becomes:
# xx = yy = zz = 1800
# xy = 400
# since
# E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800
#
# Also,

# dSrr dSrz Srr-Stt
# ---- + ---- + ------- + br = 0
# dr dz r

# dSrz Srz dSzz

# Srr = stress in rr

#
# 1-D spherical Gap Heat Transfer Test
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two "blocks" with a mesh biased toward the gap
# between them. Each block is unit length. The gap between them is one
# unit in length.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks, or spheres in the case of RSPHERICAL.:
#
# Flux = (T_left - T_right) * (gapK/(r^2*((1/r1)-(1/r2))))
#
# For gapK = 1 (default value)
#
# The area is taken as the area of the slave (inner) surface:
#
# Area = 4 * pi * 1 * 1
#
# The integrated heat flux across the gap at time 2 is then:
#
# 4*pi*k*delta_T/((1/r1)-(1/r2))
# 4*pi*1*100/((1/1) - (1/2)) = 2513.3 watts
#
# For comparison, see results from the flux post processors.

# 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!

# Patch Test
# This test is designed to compute displacements from a thermal strain.
# 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.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-6. Therefore, the strain (and the displacement
# since this is a unit cube) is 1e-4.

# Gravity Test
#
# This test is designed to exercise the gravity body force rz kernel.
#
# The mesh for this problem is a rectangle 10 units by 1 unit.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero at the top. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(y) = -b*y^2/(2*E)+b*L*y/E
#
# The displacement at y=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(y) = b*(L-y)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at y=0. The stress
# is reported at element centers. The element closest to y=0 sits
# at y = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at y = L where the stress is zero analytically. The nearest
# element is at y=9.75 where the stress is 10.

# This test is designed to compute displacements from a thermal strain.
# 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.
# The temperature moves 100 degrees, and the coefficient of thermal
# expansion is 1e-6. Therefore, the strain (and the displacement
# since this is a unit cube) is 1e-4.

# Gravity Test
#
# This test is designed to exercise the gravity body force kernel.
#
# The mesh for this problem is a rectangular bar 10 units by 1 unit
# by 1 unit.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at x=0. The stress
# is reported at element centers. The element closest to x=0 sits
# at x = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at x = L where the stress is zero analytically. The nearest
# element is at x=9.75 where the stress is 10.

# This test evaluates the capability of HeatConductionMaterial to define
# thermal conductivity as a function of temperature. The test uses the patch test
# cube mesh with a flux bc on one side and a temperature bc on the opposite side.
# The temperature bc changes as a function of time from 100 to 200. The thermal
# conductivity is a function of temperature, with k = 1 for temps = 100-199, k = 2
# for temps _>_ 200. The flux, q = 10 is constant. The Transient Executioner is used here
# although the interial kernel is omitted, so this is really a series of two steady-state

# The displacement at x=L is b*L^2/(2*E) = 2*20*10*10/(2*1e6) = 0.002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*10 = 400.
#
# Note: The simulation does not measure stress at x=0. The stress
# is reported at element centers. The element closest to x=0 sits
# at x = 1/4 and has a stress of 390. This matches the linear
# stress distribution that is expected. The same situation applies
# at x = L where the stress is zero analytically. The nearest
# element is at x=9.75 where the stress is 10.

# This problem is modified from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
# The original stress solution is given as:
# xx = yy = zz = 2000
# xy = 400
#
# Here, E=1e6 and nu=0.25.
# However, with a +100 degree change in temperature and a coefficient
# of thermal expansion of 1e-6, the solution becomes:
# xx = yy = zz = 1800
# xy = 400
# since
# E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800
#
# Also,
#
# dSrr dSrz Srr-Stt
# ---- + ---- + ------- + br = 0
# dr dz r
#
# and
#
# dSrz Srz dSzz
# ---- + --- + ---- + bz = 0
# dr r dz
#
# where
# Srr = stress in rr
# Szz = stress in zz
# Stt = stress in theta-theta
# Srz = stress in rz
# br = body force in r direction
# bz = body force in z direction
#
# This test is meant to exercise the Jacobian. To that end, the body
# force has been turned off. This makes the results differ slightly
# from the original values, but requires a correct Jacobian for minimal
# iterations. Iteration plotting is turned on to ensure that the
# number of iterations needed does not increase.

# This test uses small strain formulation, and the use_displaced_mesh
# is set to false for the kernels
#
# Gravity Test
#
# This test is similar to the other gravity tests, but it also tests the
# capability in MaterialTensorAux to return the stress of a single,
# specified integration point, rather than the element average.
# To get the stress at a single integration point, set the parameter
# qp_select to the integration point number (i.e. 0-9 for a quad 8)
# in the AuxKernel
#
# The mesh for this problem is a unit square.
#
# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.
#
# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*1*1/(2*1e6) = 0.00002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*1 = 40.
#
# Note: The isoparametric coordinate for a quad8 (fourth order) element
# is: +/- 0.77459667 and 0. For a 1 unit square with the edge of
# the element in the x = 0 plane, there would be an integration point
# at x_coordinate 0.5 - 0.5*0.77459667 (0.11270167), 0.5, and
# 0.50 + 0.5*0.77459667 (0.88729834).
#
# The corresponding stresses are:
#
# S(0.11270167) = 40(1-0.11270167) = 35.491933
# S(0.5) = 40(1-0.5) = 20
# S(0.88729834) = 40(1-0.88729834) = 4.5080664
#
# These stresses are a precise match to the simulation result.

# 1-D Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks in the x-y plane. Each element block
# is a square. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far bottom boundary
# is ramped from 100 to 200 over one time unit. The temperature of the far top
# boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks:
#
# Flux = (T_left - T_right) * (gapK/gap_width)
#
# The gap conductivity is specified as 1, thus
#
# gapK(Tavg) = 1.0*Tavg
#
# The heat flux across the gap at time = 1 is then:
#
# Flux = 100 * (1.0/1.0) = 100
#
# For comparison, see results from the flux post processors. These results
# are the same as for the unit 1-D gap heat transfer between two unit cubes.

# 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
# stress xx = 2.4e5 * 12e-6 + 2*2.4e5*2e-6 = 3.84
# stress yy = 2.4e5 * 12e-6 + 2*2.4e5*4e-6 = 4.80
# stress zz = 2.4e5 * 12e-6 + 2*2.4e5*6e-6 = 5.76
# stress xy = 2 * 2.4e5 * 2e-6 / 2 = 0.48
# (2 * G * gamma_xy / 2 = 2 * G * epsilon_xy)
# stress yz = 2 * 2.4e5 * 4e-6 / 2 = 0.96
# stress xz = 2 * 2.4e5 * 6e-6 / 2 = 1.44

# This problem is modified from the Abaqus verification manual:

# The original stress solution is given as:
# xx = yy = zz = 2000
# xy = 400
#
# Here, E=1e6 and nu=0.25.

# of thermal expansion of 1e-6, the solution becomes:
# xx = yy = zz = 1800
# xy = 400
# since
# E*(1-nu)/(1+nu)/(1-2*nu)*(1+2*nu/(1-nu))*(1e-3-1e-4) = 1800

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

# Gravity Test
#
# This test is similar to the other gravity tests, but it also tests the
# capability in MaterialTensorAux to return the stress of a single,
# specified integration point, rather than the element average.
# To get the stress at a single integration point, set the parameter
# qp_select to the integration point number (i.e. 0-9 for a quad 8)
# in the AuxKernel
#
# The mesh for this problem is a unit square.

# The boundary conditions for this problem are as follows. The
# displacement is zero on each of side that faces a negative
# coordinate direction. The acceleration of gravity is 20.

# The material has a Young's modulus of 1e6 and a density of 2.
#
# The analytic solution for the displacement along the bar is:
#
# u(x) = -b*x^2/(2*E)+b*L*x/E
#
# The displacement at x=L is b*L^2/(2*E) = 2*20*1*1/(2*1e6) = 0.00002.
#
# The analytic solution for the stress along the bar assuming linear
# elasticity is:
#
# S(x) = b*(L-x)
#
# The stress at x=0 is b*L = 2*20*1 = 40.
#
# Note: The isoparametric coordinate for a quad8 (fourth order) element
# is: +/- 0.77459667 and 0. For a 1 unit square with the edge of
# the element in the x = 0 plane, there would be an integration point
# at x_coordinate 0.5 - 0.5*0.77459667 (0.11270167), 0.5, and
# 0.50 + 0.5*0.77459667 (0.88729834).
#
# The corresponding stresses are:
#
# S(0.11270167) = 40(1-0.11270167) = 35.491933
# S(0.5) = 40(1-0.5) = 20
# S(0.88729834) = 40(1-0.88729834) = 4.5080664
#
# These stresses are a precise match to the simulation result.

#
# 2-D RZ Gap Heat Transfer Test without mechanics
#
# This test exercises 1-D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of two element blocks containing one element each. Each
# element is a unit cube. They sit next to one another with a unit between them.
#
# The conductivity of both blocks is set very large to achieve a uniform temperature
# across each block. The temperature of the far left boundary
# is ramped from 100 to 200 over one time unit, and then held fixed for an additional
# time unit. The temperature of the far right boundary is held fixed at 100.
#
# A simple analytical solution is possible for the heat flux between the blocks, or cylinders in the case of RZ.:
#
# Flux = (T_left - T_right) * (gapK/(r*ln(r2/r1)))
#
# For gapK = 1 (default value)
#
# The integrated heat flux across the gap at time 2 is then:
#
# 2*pi*h*k*delta_T/(ln(r2/r1))
# 2*pi*1*1*100/(ln(2/1)) = 906.5 watts
#
# For comparison, see results from the flux post processors.
#
# As a second test, use the rectilinear (parallel plate) form of the gap heat transfer.
#
# Flux = (T_left - T_right) * (gapK/gapL)
#
# For gapK = 1 (default value)
#
# The integrated heat flux across the gap at time 2 is then:
#
# 2*pi*h*k*delta_T/(1)
# 2*pi*1*1*100/(1) = 628.3 watts
#
# For comparison, see results from the flux post processors.

# 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

# This is a test designed to evaluate the cabability of the
# IterationAdaptiveDT TimeStepper to adjust time step size according to
# a function. For example, if the power input function for a BISON
# simulation rapidly increases or decreases, the IterationAdaptiveDT
# TimeStepper should take time steps small enough to capture the
# oscillation.

#
# This problem is taken from the Abaqus verification manual:
# "1.5.4 Patch test for axisymmetric elements"
# The stress solution is given as:
# xx = yy = zz = 19900
# xy = 0
#
# If strain = log(1+1e-2) = 0.00995033...
# then
# stress = E/(1+PR)/(1-2*PR)*(1-PR +PR +PR)*strain = 19900.6617
# with E = 1e6 and PR = 0.25.
#
# The code computes stress = 19900.6617 when
# increment_calculation = eigen. There is a small error when the
# rashidapprox option is used.
