Class
Foam::globalProcFaceIndex
Description
The class creates a unique global face index for each processor face (pair)
in the mesh. Master and slave processor face carry the same index.
The data is presented as a labelListList, which is set only for
processor patches.
Face offsets counts a number of unique faces on each processor,
excluding slave processor patch faces, which are given master face index.
If needed, global face indes from all faces can be derived from this data
Currently, faces are ordered with internal faces first, followed by patch
faces in patch order, excluding slave processor patches.
If needed, this can be changed to group processor faces with internal faces
to facilitate parallel I/O. HJ, 4/May/2018
