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
