Description
Utility to create patches out of selected boundary faces. Faces come either
from existing patches or from a faceSet.
More specifically it:
- creates new patches (from selected boundary faces). Synchronise faces
on coupled patches.
- synchronises points on coupled boundaries
- remove patches with 0 faces in them
