- boundariesThe name of the boundary to mesh
C++ Type:std::vector
Description:The name of the boundary to mesh
- block_idSubdomain id to set for the new elements along the boundary
C++ Type:unsigned short
Description:Subdomain id to set for the new elements along the boundary
MeshSideSet
Add lower dimensional elements along the faces contained in a side set to set up mixed dimensional problems
Element sides are not explicitly meshed in MOOSE/libmesh, i.e. no shape functions live on the lower dimensional sides. To run kernels on lower dimensional manifolds they need to be explicitly meshed. That can be accomplished in a mesh generation tool like Cubit, or using this MeshModifier.
In 3D simulations the appropriate 2D elements (And for 2D simulations 1D elements) will be meshed in at selected side sets (boundaries). The choice of lower dimensional side elements is dictated by the higher dimensional volume element types.
Coupling between side and volume meshes
The newly generated lower dimensional side elements will share nodes with the higher dimensional volumes elements. Coupling to the variables from volume elements in "just works".
Coupling in the other direction is not as straight forward. The lower dimensional variables exist on some nodes of the adjacent volume elements. The volume kernels will run on the volume quadrature points at which _tapered off_ values from the adjacent edges van be found. Use at your own risk.
Input Parameters
- force_prepareFalseNormally all MeshModifiers run before the mesh is prepared for use. This flag can be set on an individual modifier to force preperation between modifiers where they might be needed.
Default:False
C++ Type:bool
Description:Normally all MeshModifiers run before the mesh is prepared for use. This flag can be set on an individual modifier to force preperation between modifiers where they might be needed.
- block_nameSubdomain name to set for the new elements along the boundary (optional)
C++ Type:SubdomainName
Description:Subdomain name to set for the new elements along the boundary (optional)
- depends_onThe MeshModifiers that this modifier relies upon (i.e. must execute before this one)
C++ Type:std::vector
Description:The MeshModifiers that this modifier relies upon (i.e. must execute before this one)
Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Description:Set the enabled status of the MooseObject.
