# XFEM Moving Interface Verification Problem
# Dimensionality:                                         2D
# Coordinate System:                                      rz
# Material Numbers/Types:   homogeneous 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 homogeneous material
#   properties. 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 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

# Two phase density-driven convection of dissolved CO2 in brine
#
# The model starts with CO2 in the liquid phase only.  The CO2 diffuses into the brine.
# As the density of the CO2-saturated brine is greater
# than the unsaturated brine, a gravitational instability arises and density-driven
# convection of CO2-rich fingers descend into the unsaturated brine.
#
# The instability is seeded by a random perturbation to the porosity field.
# Mesh adaptivity is used to refine the mesh as the fingers form.
#
# Note: this model is computationally expensive, so should be run with multiple cores.

# 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

# Poroelastic response of a borehole.
#
# HIGHRES VERSION: this version gives good agreement with the analytical solution, but it takes a while so is a "heavy" test
#
# A fully-saturated medium contains a fluid with a homogeneous porepressure,
# but an anisitropic insitu stress.  A infinitely-long borehole aligned with
# the $$z$$ axis is instanteously excavated.  The borehole boundary is
# stress-free and allowed to freely drain.  This problem is analysed using
# plane-strain conditions (no $$z$$ displacement).
#
# The solution in Laplace space is found in E Detournay and AHD Cheng "Poroelastic response of a borehole in a non-hydrostatic stress field".  International Journal of Rock Mechanics and Mining Sciences and Geomechanics Abstracts 25 (1988) 171-182.  In the small-time limit, the Laplace transforms may be performed.  There is one typo in the paper.  Equation (A4)'s final term should be -(a/r)\sqrt(4ct/(a^2\pi)), and not +(a/r)\sqrt(4ct/(a^2\pi)).
#
# Because realistic parameters are chosen (below),
# the residual for porepressure is much smaller than
# the residuals for the displacements.  Therefore the
# scaling parameter is chosen.  Also note that the
# insitu stresses are effective stresses, not total
# stresses, but the solution in the above paper is
# expressed in terms of total stresses.
#
# Here are the problem's parameters, and their values:
# Borehole radius.  a = 1
# Rock's Lame lambda.  la = 0.5E9
# Rock's Lame mu, which is also the Rock's shear modulus.  mu = G = 1.5E9
# Rock bulk modulus.  K = la + 2*mu/3 = 1.5E9
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.125
# Rock bulk compliance.  1/K = 0.66666666E-9
# Fluid bulk modulus.  Kf = 0.7171315E9
# Fluid bulk compliance.  1/Kf = 1.39444444E-9
# Rock initial porosity.  phi0 = 0.3
# Biot coefficient.  alpha = 0.65
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 2E9
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.345E9
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.2364
# Skempton coefficient.  B = alpha*M/Ku = 0.554
# Fluid mobility (rock permeability/fluid viscosity).  k = 1E-12

# using RichardsMultiphaseProblem to bound pgas.  i take big timesteps to illustrate that the bounding works.  Note that s_res for gas = 0, in order to prevent the simulation from trying to reduce pgas at small x in order to conserve fluid mass by decreasing the density.  Because there is zero gas to begin with, but due to numerical inprecisions there is some gas at the end, the mass error for the gas is 0.5.

# The primary purpose of this test is to verify that the ability to combine
# multiple eigenstrains works correctly.  It should behave identically to the
# constant_expansion_coeff.i model in the thermal_expansion directory. Instead
# of having the eigenstrain names passed directly to the SolidMechanics QuasiStatic Physics,
# the QuasiStatic Physics should be able to extract the necessary eigenstrains and apply
# to their respective blocks without reduncacy.

# This test involves only thermal expansion strains on a 2x2x2 cube of approximate
# steel material.  An initial temperature of 25 degrees C is given for the material,
# and an auxkernel is used to calculate the temperature in the entire cube to
# raise the temperature each time step.  After the first timestep,in which the
# temperature jumps, the temperature increases by 6.25C each timestep.
# The thermal strain increment should therefore be
#     6.25 C * 1.3e-5 1/C = 8.125e-5 m/m.

# Illustrates desorption works as planned.
#
# A mesh contains 3 elements in arranged in a line.
# The central element contains desorped fluid.
# This desorps to the nodes of that element.
#
# In the central element, of volume V, the following occurs.
# The initial porepressure=1, and concentration=1.
# The initial mass of fluid is
# V * (2 * porosity * density + (1 - porosity) * concentration)
# = V * 1.289547
# Notice the factor of "2" in the porespace contribution:
# it is because the porepressure is evaluated at nodes, so
# the nodes on the exterior of the centre_block have
# nodal-volume contributions from the elements not in centre_block.
#
# The mass-conservation equation reads
# 2 * porosity * density + (1 - porosity) * concentration = 1.289547
# and the desorption equation reads
# d( (1-porosity)C )/dt = - (1/tau)(C - dens_L * P / (P_L + P))
# where C = concentration, P = porepressure, P_L = Langmuir pressure
# dens_L = Langmuir density, tau = time constant.
# Using the mass-conservation equation in the desorption equation
# yields a nonlinear equation of P.  For dt=1, and the numerical values
# given below this yields
# P = 1.83697
# and
# C = 0.676616
# The desired result is achieved by MOOSE

# 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

# Basic example coupling a master and sub app at an interface in a 2D model.
# The master app provides a flux term to the sub app via Functional Expansions, which then performs
# its calculations.  The sub app's interface conditions, both value and flux, are transferred back
# to the master app

# Poroelastic response of a borehole.
#
# LOWRES VERSION: this version does not give perfect agreement with the analytical solution
#
# A fully-saturated medium contains a fluid with a homogeneous porepressure,
# but an anisitropic insitu stress.  A infinitely-long borehole aligned with
# the $$z$$ axis is instanteously excavated.  The borehole boundary is
# stress-free and allowed to freely drain.  This problem is analysed using
# plane-strain conditions (no $$z$$ displacement).
#
# The solution in Laplace space is found in E Detournay and AHD Cheng "Poroelastic response of a borehole in a non-hydrostatic stress field".  International Journal of Rock Mechanics and Mining Sciences and Geomechanics Abstracts 25 (1988) 171-182.  In the small-time limit, the Laplace transforms may be performed.  There is one typo in the paper.  Equation (A4)'s final term should be -(a/r)\sqrt(4ct/(a^2\pi)), and not +(a/r)\sqrt(4ct/(a^2\pi)).
#
# Because realistic parameters are chosen (below),
# the residual for porepressure is much smaller than
# the residuals for the displacements.  Therefore the
# scaling parameter is chosen.  Also note that the
# insitu stresses are effective stresses, not total
# stresses, but the solution in the above paper is
# expressed in terms of total stresses.
#
# Here are the problem's parameters, and their values:
# Borehole radius.  a = 1
# Rock's Lame lambda.  la = 0.5E9
# Rock's Lame mu, which is also the Rock's shear modulus.  mu = G = 1.5E9
# Rock bulk modulus.  K = la + 2*mu/3 = 1.5E9
# Drained Poisson ratio.  nu = (3K - 2G)/(6K + 2G) = 0.125
# Rock bulk compliance.  1/K = 0.66666666E-9
# Fluid bulk modulus.  Kf = 0.7171315E9
# Fluid bulk compliance.  1/Kf = 1.39444444E-9
# Rock initial porosity.  phi0 = 0.3
# Biot coefficient.  alpha = 0.65
# Biot modulus.  M = 1/(phi0/Kf + (alpha - phi0)(1 - alpha)/K) = 2E9
# Undrained bulk modulus. Ku = K + alpha^2*M = 2.345E9
# Undrained Poisson ratio.  nuu = (3Ku - 2G)/(6Ku + 2G) = 0.2364
# Skempton coefficient.  B = alpha*M/Ku = 0.554
# Fluid mobility (rock permeability/fluid viscosity).  k = 1E-12

# 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

# Illustrates desorption works as planned.
#
# A mesh contains 3 elements in arranged in a line.
# The central element contains desorped fluid.
# This desorps to the nodes of that element.
#
# In the central element, of volume V, the following occurs.
# The initial porepressure=1, and concentration=1.
# The initial mass of fluid is
# V * (2 * porosity * density + (1 - porosity) * concentration)
# = V * 1.289547
# Notice the factor of "2" in the porespace contribution:
# it is because the porepressure is evaluated at nodes, so
# the nodes on the exterior of the centre_block have
# nodal-volume contributions from the elements not in centre_block.
#
# The mass-conservation equation reads
# 2 * porosity * density + (1 - porosity) * concentration = 1.289547
# and the desorption equation reads
# d( (1-porosity)C )/dt = - (1/tau)(C - dens_L * P / (P_L + P))
# where C = concentration, P = porepressure, P_L = Langmuir pressure
# dens_L = Langmuir density, tau = time constant.
# Using the mass-conservation equation in the desorption equation
# yields a nonlinear equation of P.  For dt=1, and the numerical values
# given below this yields
# P = 1.83697
# and
# C = 0.676616
# The desired result is achieved by MOOSE

# XFEM Moving Interface Verification Problem
# Dimensionality:                                         2D
# Coordinate System:                                      xy
# Material Numbers/Types:   homogeneous 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 homogeneous material
#   properties. 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 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

# XFEM Moving Interface Verification Problem
# Dimensionality:                                   quasi-1D
# Coordinate System:                                      rz
# Material Numbers/Types:   homogeneous 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 a single, constant value at all points in the system.
# 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

# XFEM Moving Interface Verification Problem
# Dimensionality:                                   quasi-1D
# Coordinate System:                                      xy
# Material Numbers/Types:   homogeneous 1 material, 2 region
# Element Order:                                         1st
# Interface Characteristics: u independent, prescribed linear 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 a single, constant value at all points in the system.
# 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

# 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

# Dimensionality:                                   quasi-1D

# Interface Characteristics: u independent, prescribed level set function
# Description
#   A 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 separating two
#   discrete material regions for linear element models. Both the temperature
#   solution and level set function are designed to be linear to attempt to
#   minimize error between the exact solution and XFEM results. Thermal
#   conductivity, density, and heat capacity are homogeneous in each material
#   region with a discontinuous jump in thermal flux between the two material
#   regions.
# Results:
#   The temperature at the left boundary is determined by the analytical
#   solution, so temperature at the right boundary (x=1) should exhibit the
#   largest difference between the analytical solution and XFEM results. We
#   present the analytical and XFEM results at the material interface position
#   and right side boundary at various times.

# 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
