Description
|
|
Utility to remove faces (combines cells on both sides).
|
|
|
|
Takes faceSet of candidates for removal and writes faceSet with faces that
|
|
will actually be removed. (because e.g. would cause two faces between the
|
|
same cells). See removeFaces in dynamicMesh library for constraints.
