Class
Foam::hexCellLooper
Description
Implementation of cellLooper.
This one walks hexes in a topological way:
- cross edge to other face
- cross face by walking edge-point-edge across to reach the other side.
(edges are always cut through the middle)
For anything else (tet, prism, .. poly) it will use geomCellLooper
(which does a purely geometric cut using a plane through cell centre)
