createPatch

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
|
|
- Synchronises faces on coupled patches
|
|
- Synchronises points on coupled patches (optional)
|
|
- Removes non-constraint patches with no faces
|
