mergeOrSplitBaffles
|
||||
|
||||
Description
|
||||
Detects faces that share points (baffles). Either merge them or
|
||||
duplicate the points.
|
||||
|
||||
Notes:
|
||||
- can only handle pairwise boundary faces. So three faces using
|
||||
the same points is not handled (is illegal mesh anyway)
|
||||
|
||||
- there is no option to only split/merge some baffles.
|
||||
|
||||
- surfaces consisting of duplicate faces can be topologically split
|
||||
if the points on the interior of the surface cannot walk to all the
|
||||
cells that use them in one go.
|
||||
|
||||
- Parallel operation (where duplicate face is perpendicular to a coupled
|
||||
boundary) is supported but not really tested.
|
||||
(Note that coupled faces themselves are not seen as duplicate faces)
