RenameBoundaryGenerator

Changes the boundary IDs and/or boundary names for a given set of boundaries defined by either boundary ID or boundary name. The changes are independent of ordering. The merging of boundaries is supported.

Renaming or Setting Boundary Names

When using the RenameBoundaryGenerator to change boundary names, the result is independent of ordering.

The following will change the name for the boundary "meaningless" to "interior" and the name for boundary "5" to "exterior":


[rename]
  type = RenameBoundaryGenerator
  input = some_mesh
  old_boundary = 'meaningless 5'
  new_boundary = 'interior exterior'
[]

For the special case where the original boundary name and ID are the same, this mesh generator will convert both to the new boundary name/ID. For instance, if the mesh contains a boundary named 3 that also has an ID of 3, this mesh generator will convert both the name and ID.

Merging Boundaries

When using the RenameBoundaryGenerator to merge boundaries, the result is not necessarily independent of ordering.

For example, take the following:


[merge]
  type = RenameBoundaryGenerator
  input = some_mesh
  old_boundary = '0 1 2 3`
  new_boundary = 'bottom_and_left bottom_and_left top_and_right top_and_right'
[]

The above will result in two boundaries:

  • Boundary "0" with name "bottom_and_left" that contains the sides from the original boundaries "0" and "1".

  • Boundary "2" with name "top_and_right" that contains the sides from the original boundaries "2" and "3".

Take the first execution, "0" to "bottom_and_left". The "RenameBoundaryGenerator" will use the original boundary ID, which is "0". The second execution, "1" to "bottom_and_left", will use the new ID associated with "bottom_and_left", which is "0", and merge "1" into it. The result is similar for the third and fourth executions.

schooltip:The use of ID is order independent

The order dependent behavior only exists when the new boundary provided is a name. Take the following instead:


[merge]
  type = RenameBoundaryGenerator
  input = some_mesh
  old_boundary = '0 1 2 3'
  new_boundary = '0 0 4 4'
[]

The result is:

  • Boundary "0" that contains the sides from original boundaries "0" and "1".

  • Boundary "4" that contains the sides from original boundaries "2" and "3".
