Class
Foam::tetIndices
Description
Storage and named access for the indices of a tet which is part of
the decomposition of a cell.
Tets are designated by
- cell (of course)
- face on cell
- three points on face (faceBasePt, facePtA, facePtB)
When constructing from a mesh and index in the face (tetPtI):
- faceBasePt is the mesh.tetBasePtIs() base point
- facePtA is tetPtI away from faceBasePt
- facePtB is next one after/before facePtA
e.g.:
+---+
|2 /|
| / |
|/ 1| <- tetPt (so 1 for first triangle, 2 for second)
+---+
^
faceBasePt
