RenameBlockGenerator

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

Renaming or Setting Block Names

When using the RenameBlockGenerator to change block names, the result is independent of ordering.

The following will change the name for the block meaningless to inside and will set the name for block 5 to outside:


[rename]
  type = RenameBlockGenerator
  input = some_mesh
  old_block = 'meaningless 5'
  new_block = 'inside outside'
[]

Merging Blocks

The RenameBlockGenerator can be used to merge blocks together. The result is independent of ordering when "new_block" contains only block IDs. When "new_block" contains block names, the result is not necessarily independent of ordering.

The following will result in the merging of the elements in blocks 1, 2, and 3 into block 0:


[merge]
  type = RenameBlockGenerator
  input = some_mesh
  old_block = '1 2 3'
  new_block = '0 0 0'
[]

As discussed previously, when providing names in "new_block", the result may be ordering-dependent. If a name is provided in "new_block" that does not already exist in the mesh, it will take the ID of the first rename.

Take the following examples (assuming that the block some_block does not exist yet):


[mergename0]
  type = RenameBlockGenerator
  input = some_mesh
  old_block = '0 1'
  new_block = 'some_block some_block'
[]


[mergename1]
  type = RenameBlockGenerator
  input = some_mesh
  old_block = '1 0'
  new_block = 'some_block some_block'
[]

The result of each will be a block named some_block that contains elements that were in blocks 0 and 1. However, because the block some_block takes the ID of the first rename execution, the ID of some_block will be 0 in the case of the generator mergename0 and 1 in the case of the generator mergename1.

In the case of providing "new_block" by ID, the following examples (assuming that the block 2 does not exist yet) will have the same result:


[mergeblock0]
  type = RenameBlockGenerator
  input = some_mesh
  old_block = '0 1'
  new_block = '2 2'
[]


[mergeblock1]
  type = RenameBlockGenerator
  input = some_mesh
  old_block = '1 0'
  new_block = '2 2'
[]

That is, a block will be created with the ID 2 that contains the elements previously in blocks 0 and 1.

In summary, the possibility of ordering-dependent results with the RenameBlockGenerator depends on whether or not name(s) are provided in "new_block" and said name(s) do not exist yet.
