Foam::polyDistributionMap
|
|

|
Description
|
|
Class containing mesh-to-mesh mapping information after a mesh distribution
|
|
where we send parts of meshes (using subsetting) to other processors
|
|
and receive and reconstruct mesh.
|
|
|
|
We store mapping from the bits-to-send to the complete starting mesh
|
|
(subXXXMap) and from the received bits to their location in the new
|
|
mesh (constructXXXMap).
