Class
Foam::meshDualiser
Description
Creates dual of polyMesh. Every point becomes a cell (or multiple cells
for feature points), a walk around every edge creates faces between them.
Put all points you want in the final mesh into featurePoints; all edge(mid)s
you want in the final mesh into featureEdges; all face(centre)s in
faceFaces.
Usually to preserve boundaries:
- all boundary faces are featureFaces
- all edges and points inbetween different patches are
featureEdges/points.
In same way you can also preserve internal faces (e.g. faceZones)
