Foam::procFacesGAMGProcAgglomeration
|
|
|
|
Description
|
|
Processor agglomeration of GAMGAgglomerations. Needs nAgglomeratingCells
|
|
which is when to start agglomerating processors. Processors get agglomerated
|
|
by constructing a single cell mesh for each processor with each
|
|
processor interface a face. This then gets agglomerated using
|
|
the pairGAMGAgglomeration algorithm with the number of faces
|
|
on the original processor interface as face weight.
