Subject: [PATCH] ENH: faMeshReconstructor for reconstructing equivalent serial
faMesh (#2084)
- A bare-bones reconstructor for finiteArea meshes when processor
meshes are available (in parallel) but an equivalent serial faMesh
is needed for reconstruction or decomposition.
In these situations, a serial version of the faMesh is needed,
but preferably without reconstructing the entire volume mesh.
It uses the finiteVolume faceProcAddressing in addition to
the geometric information available from the underlying polyMesh.
The resulting equivalent faMesh can be used for basic operations,
but caution should be exercised before attempting large operations.
