AssignElementSubdomainID

under construction:Undocumented Class

The AssignElementSubdomainID has not been documented. The content contained on this page includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

!syntax description /MeshModifiers/AssignElementSubdomainID

Input Parameters

subdomain_idsNew subdomain IDs of all elements
C++ Type:std::vector
Options:
Description:New subdomain IDs of all elements

Required 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
Options:
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.
depends_onThe MeshModifiers that this modifier relies upon (i.e. must execute before this one)
C++ Type:std::vector
Options:
Description:The MeshModifiers that this modifier relies upon (i.e. must execute before this one)
element_idsNew subdomain IDs of all elements
C++ Type:std::vector
Options:
Description:New subdomain IDs of all elements

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector
Options:
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Options:
Description:Set the enabled status of the MooseObject.
