FunctionNeumannBC
Imposes the integrated boundary condition , where is a (possibly) time and space-dependent MOOSE Function.
Description
FunctionNeumannBC is a generalization of NeumannBC which is used for imposing flux boundary conditions on systems of partial differential equations (PDEs) where the flux is represented by a spatially- and temporally-varying MOOSE Function. That is, for a PDE of the form where is the domain, and is its boundary, a FunctionNeumannBC object can be used to impose condition (3) if the function is well-defined for all relevant times and . In this case, the function parameter corresponds to a MOOSE Function object which represents the mathematical function , and the user must define one or more sidesets corresponding to the boundary subset via the boundary parameter.

- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary. In the default nearest_node_connected_sides algorithm, primary boundary elements are searched iff that nearest node is one of their nodes. This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).

# 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
# 0.8 560 560.0088286

# 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

# 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

# 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
# 0.2 440 440
# 0.4 480 479.9998745
# 0.6 520 519.9995067
# 0.8 560 559.9989409

# 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
# 0.2 440 440
# 0.4 480 480.0008118
# 0.6 520 520.0038529
# 0.8 560 560.0089177

# XFEM Moving Interface Verification Problem
# Dimensionality: quasi-1D
# Coordinate System: xy
# Material Numbers/Types:discrete homog 2 material, 2 region
# Element Order: 1st
# 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.
# Interface:
# Time Expected Temperature XFEM Calculated Temperature

# 40 893.05 893.0379081

# 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
# 0.6 520 519.9995114

# Beam bending.
# One end is clamped and the other end is subjected to a stress
# and micromechanical moment that will induce bending.
# The stress that will induce bending around the y axis is
# stress_xx = EAz
# This implies a micromechanical moment-stress of
# m_yx = (1/12)EAh^2 for joint_shear_stiffness=0.
# For joint_shear_stiffness!=0, the micromechanical moment-stress
# is
# m_yx = (1/12)EAa^2 G/(ak_s + G)
# All other stresses and moment stresses are assumed to be zero.
# With joint_shear_stiffness=0, and introducing D=-poisson*A, the
# nonzero strains are
# ep_xx = Az
# ep_yy = Dz
# ep_zz = Dz
# kappa_xy = -D
# kappa_yx = A
# This means the displacements are:
# u_x = Axz
# u_y = Dzy
# u_z = -(A/2)x^2 + (D/2)(z^2-y^2)
# wc_x = -Dy
# wc_y = Ax
# wc_z = 0
# This is bending of a bar around the y axis, in plane stress
# (stress_yy=0). Displacements at the left-hand (x=0) are applied
# according to the above formulae; wc_x and wc_y are applied throughout
# the bar; and stress_xx is applied at the right-hand end (x=10).
# The displacements are measured and
# compared with the above formulae.
# The test uses: E=1.2, poisson=0.3, A=1.11E-2, h=2, ks=0.1, so
# stress_xx = 1.332E-2*z

# 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
# 0.2 440 440
# 0.4 480 480.0000064
# 0.6 520 520.0000323
# 0.8 560 560.0000896
