Description
|
|
Makes internal faces into boundary faces. Does not duplicate points, unlike
|
|
mergeOrSplitBaffles.
|
|
|
|
Note: if any coupled patch face is selected for baffling the opposite
|
|
member has to be selected for baffling as well. Note that this
|
|
is the same as repatching. This was added only for convenience so
|
|
you don't have to filter coupled boundary out of your set.
