- inputThe mesh we want to modify
C++ Type:MeshGeneratorName
Controllable:No
Description:The mesh we want to modify
- new_boundaryThe name of the boundary to create
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The name of the boundary to create
- pointsA list of points from which to start painting sidesets
C++ Type:std::vector<libMesh::Point>
Controllable:No
Description:A list of points from which to start painting sidesets
SideSetsFromPointsGenerator
Adds a new sideset starting at the specified point containing all connected element faces with the same normal.
This is similar to the SideSetFromNormalsGenerator but may be easier to use if the user knows the external coordinates on the mesh without knowing the normal vector around those points. Multiple points can be provided to define multiple sidesets.
Input Parameters
- fixed_normalFalseThis Boolean determines whether we fix our normal or allow it to vary to "paint" around curves
Default:False
C++ Type:bool
Controllable:No
Description:This Boolean determines whether we fix our normal or allow it to vary to "paint" around curves
- replaceFalseIf true, replace the old sidesets. If false, the current sidesets (if any) will be preserved.
Default:False
C++ Type:bool
Controllable:No
Description:If true, replace the old sidesets. If false, the current sidesets (if any) will be preserved.
- 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)
- variance0.1The variance [0.0 - 1.0] allowed when comparing normals
Default:0.1
C++ Type:double
Controllable:No
Description:The variance [0.0 - 1.0] allowed when comparing normals
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.
