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. More...

Detailed 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.
