FileMeshGenerator

Read a mesh from a file.

Supported File Formats

The FileMeshGenerator is the default type for MOOSE and as the name suggests it reads the mesh from an external file. MOOSE supports reading and writing a large number of formats and could be extended to read more.

Extension	Description
.e, .exd	Sandia's ExodusII format
.dat	Tecplot ASCII file
.fro	ACDL's surface triangulation file
.gmv	LANL's GMV (General Mesh Viewer) format
.mat	Matlab triangular ASCII file (read only)
.msh	GMSH ASCII file
.n, .nem	Sandia's Nemesis format
.plt	Tecplot binary file (write only)
.node, .ele; .poly	TetGen ASCII file (read; write)
.inp	Abaqus .inp format (read only)
.ucd	AVS's ASCII UCD format
.unv	I-deas Universal format
.xda, .xdr	libMesh formats
.vtk, .pvtu	Visualization Toolkit
.cpr	Checkpoint file

When reading a mesh file in Sandia's ExodusII format, users can use parameter exodus_extra_element_integers to load elemental variables for setting extra element integers of the mesh. The names of the extra element integers will be the same as the names of the element variables in the mesh file. This generator can also be used for restarting variables from the Exodus file format. In order to indicate that the mesh file can be used to restart variables, simply set the parameter use_for_exodus_restart = true. The initial_from_file_var parameter must also be set in the variables sub-block as described in Restart in order to perform variable restart.

Input Parameters

fileThe filename to read.
C++ Type:MeshFileName
Controllable:No
Description:The filename to read.

Required Parameters

allow_renumberingTrueWhether to allow the mesh to renumber nodes and elements. Note that this parameter is only relevant for non-exodus files, e.g. if reading from checkpoint for example. For exodus we always disallow renumbering.
Default:True
C++ Type:bool
Controllable:No
Description:Whether to allow the mesh to renumber nodes and elements. Note that this parameter is only relevant for non-exodus files, e.g. if reading from checkpoint for example. For exodus we always disallow renumbering.
clear_spline_nodesFalseIf clear_spline_nodes=true, IsoGeometric Analyis spline nodes and constraints are removed from an IGA mesh, after which only C^0 Rational-Bernstein-Bezier elements will remain.
Default:False
C++ Type:bool
Controllable:No
Description:If clear_spline_nodes=true, IsoGeometric Analyis spline nodes and constraints are removed from an IGA mesh, after which only C^0 Rational-Bernstein-Bezier elements will remain.
exodus_extra_element_integersThe variable names in the mesh file for loading extra element integers
C++ Type:std::vector<std::string>
Controllable:No
Description:The variable names in the mesh file for loading extra element integers
show_infoFalseWhether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Default:False
C++ Type:bool
Controllable:No
Description:Whether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
skip_partitioningFalseTrue to skip partitioning, only after this mesh generator, because the mesh was pre-split for example.
Default:False
C++ Type:bool
Controllable:No
Description:True to skip partitioning, only after this mesh generator, because the mesh was pre-split for example.
use_for_exodus_restartFalseTrue to indicate that the mesh file this generator is reading can be used for restarting variables
Default:False
C++ Type:bool
Controllable:No
Description:True to indicate that the mesh file this generator is reading can be used for restarting variables

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.

# Strata deformation and fracturing around a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young's modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = 0.025*z MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1

#
# 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.

# Strata deformation and fracturing around a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# Time is meaningless in this example
# as quasi-static solutions are sought at each timestep, but
# the number of timesteps controls the resolution of the
# process.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young's modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa.  The initial stress is consistent with
# the weight force from density 2500 kg/m^3, ie, stress_zz = 0.025*z MPa
# where gravity = 10 m.s^-2 = 1E-5 MPa m^2/kg.  The maximum and minimum
# principal horizontal stresses are assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 3 MPa
# MC friction angle = 37 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1

# Using the results from the equilibrium run to provide the initial condition for
# porepressure, we now inject a gas phase into the brine-saturated reservoir. In this
# example, where the mesh used is identical to the mesh used in gravityeq.i, we can use
# the basic restart capability by simply setting the initial condition for porepressure
# using the results from gravityeq.i.
#
# Even though the gravity equilibrium is established using a 2D mesh, in this example,
# we shift the mesh 0.1 m to the right and rotate it about the Y axis to make a 2D radial
# model.
#
# Methane injection takes place over the surface of the hole created by rotating the mesh,
# and hence the injection area is 2 pi r h. We can calculate this using an AreaPostprocessor,
# and then use this in a ParsedFunction to calculate the injection rate so that 10 kg/s of
# methane is injected.
#
# Results can be improved by uniformly refining the initial mesh.
#
# Note: as this example uses the results from a previous simulation, gravityeq.i MUST be
# run before running this input file.

# 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 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.

# Test for displacement of pinched cylinder
# Ref: Figure 10 and Table 6 from Dvorkin and Bathe, Eng. Comput., Vol. 1, 1984.

# A cylinder of radius 1 m and length 2 m (along Z axis) with clamped ends
# (at z = 0 and 2 m) is pinched at mid-length by placing point loads of 10 N
# at (1, 0, 1) and (-1, 0, 1). Due to the symmetry of the problem, only 1/8th
# of the cylinder needs to be modeled.

# The normalized series solution for the displacement at the loading point is
# w = Wc E t / P = 164.24; where Wc is the displacement in m, E is the Young's
# modulus, t is the thickness and P is the point load.

# For this problem, E = 1e6 Pa, L = 2 m, R = 1 m, t = 0.01 m, P = 10 N and
# Poisson's ratio = 0.3. FEM results from different mesh discretizations are
# presented below. Only the 10x10 mesh is included as a test.

# Mesh of 1/8 cylinder |  FEM/analytical (Moose) | FEM/analytical (Dvorkin)
#                      |ratio of normalized disp.| ratio of normalized disp.
#----------------------|-------------------------|-------------------------
#     10 x 10          |          0.806          |        0.83
#     20 x 20          |          1.06           |        0.96
#     40 x 40          |          0.95           |         -
#     80 x 160         |          0.96           |         -

# The results from FEM analysis matches well with the series solution and with

# Strata deformation and fluid flow aaround a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# The excavation takes 0.5 years.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
#  - no flow at x=0, z=-400 and z=0
#  - fixed porepressure at y=-1000, y=1000 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# A single-phase unsaturated fluid is used.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa, and time units are measured in years.
#
# The initial porepressure is hydrostatic with P=0 at z=0, so
# Porepressure ~ - 0.01*z MPa, where the fluid has density 1E3 kg/m^3 and
# gravity = = 10 m.s^-2 = 1E-5 MPa m^2/kg.
# To be more accurate, i use
# Porepressure = -bulk * log(1 + g*rho0*z/bulk)
# where bulk=2E3 MPa and rho0=1Ee kg/m^3.
# The initial stress is consistent with the weight force from undrained

# Strata deformation and fluid flow aaround a coal mine - 3D model
#
# A "half model" is used.  The mine is 400m deep and
# just the roof is studied (-400<=z<=0).  The mining panel
# sits between 0<=x<=150, and 0<=y<=1000, so this simulates
# a coal panel that is 300m wide and 1000m long.  The outer boundaries
# are 1km from the excavation boundaries.
#
# The excavation takes 0.5 years.
#
# The boundary conditions for this simulation are:
#  - disp_x = 0 at x=0 and x=1150
#  - disp_y = 0 at y=-1000 and y=1000
#  - disp_z = 0 at z=-400, but there is a time-dependent
#               Young modulus that simulates excavation
#  - wc_x = 0 at y=-1000 and y=1000
#  - wc_y = 0 at x=0 and x=1150
#  - no flow at x=0, z=-400 and z=0
#  - fixed porepressure at y=-1000, y=1000 and x=1150
# That is, rollers on the sides, free at top,
# and prescribed at bottom in the unexcavated portion.
#
# A single-phase unsaturated fluid is used.
#
# The small strain formulation is used.
#
# All stresses are measured in MPa, and time units are measured in years.
#
# The initial porepressure is hydrostatic with P=0 at z=0, so
# Porepressure ~ - 0.01*z MPa, where the fluid has density 1E3 kg/m^3 and
# gravity = = 10 m.s^-2 = 1E-5 MPa m^2/kg.
# To be more accurate, i use
# Porepressure = -bulk * log(1 + g*rho0*z/bulk)
# where bulk=2E3 MPa and rho0=1Ee kg/m^3.
# The initial stress is consistent with the weight force from undrained
# density 2500 kg/m^3, and fluid porepressure, and a Biot coefficient of 0.7, ie,
# stress_zz^effective = 0.025*z + 0.7 * initial_porepressure
# The maximum and minimum principal horizontal effective stresses are
# assumed to be equal to 0.8*stress_zz.
#
# Material properties:
# Young's modulus = 8 GPa
# Poisson's ratio = 0.25
# Cosserat layer thickness = 1 m
# Cosserat-joint normal stiffness = large
# Cosserat-joint shear stiffness = 1 GPa
# MC cohesion = 2 MPa
# MC friction angle = 35 deg
# MC dilation angle = 8 deg
# MC tensile strength = 1 MPa
# MC compressive strength = 100 MPa
# WeakPlane cohesion = 0.1 MPa
# WeakPlane friction angle = 30 deg
# WeakPlane dilation angle = 10 deg
# WeakPlane tensile strength = 0.1 MPa
# WeakPlane compressive strength = 100 MPa softening to 1 MPa at strain = 1
# Fluid density at zero porepressure = 1E3 kg/m^3
# Fluid bulk modulus = 2E3 MPa
# Fluid viscosity = 1.1E-3 Pa.s = 1.1E-9 MPa.s = 3.5E-17 MPa.year

# This problem consists of two beams with different prescribed temperatures on
# the top of the top beam and the bottom of the bottom beam.  The top beam is
# fixed against vertical displacement on the top surface, and the bottom beam
# bends downward due to thermal expansion.

# This is a test of the effectiveness of the Jacobian terms coupling temperature
# and displacement for thermal contact. The Jacobian is not exactly correct,
# but is close enough that this challenging problem converges in a small number
# of nonlinear iterations using NEWTON.

#
# 2D Cylindrical Gap Heat Transfer Test.
#
# This test exercises 2D gap heat transfer for a constant conductivity gap.
#
# The mesh consists of an inner solid cylinder of radius = 1 unit, and outer
# hollow cylinder with an inner radius of 2 in the y-z plane. In other words,
# the gap between them is 1 radial unit in length.
#
# The calculated results are the same as for the cyl2D.i case in the x-y plane.
