Add BoundaryPatchTouchingVerticesProperty
This addresses the TODO item
Add methods to create the a BoundaryPatch containing all faces
touching a set of vertices.
The BoundaryPatchTouchingVerticesProperty
is a modification of the BoundaryPatchEnclosingVerticesProperty
that took me approximately 1min to write (downside: I did not test it).
I'm not sure if anyone actually needs this feature (anymore). Either way, the TODO item is now obsolete because we can just accept this merge request if we feel like it (or reject it -- also no harm done. It'll still be available in the archive).
