Algorithm for coarsening a graph with structured aggregation.
Use the logical indexing of the mesh to obtain a very regular aggregation pattern and maintain lines and planes of the problem as they might be useful to the smoother. This algorithms is also very easy to parallelize on node due to its very regular and predictible memory access patern.
Parameter | Meaning |
---|---|
aggregation: coarsen | describe the coarsening rate to be used in each direction |
Use the logical indexing of the mesh to obtain a very regular aggregation pattern and maintain lines and planes of the problem as they might be useful to the smoother. This algorithms is also very easy to parallelize on node due to its very regular and predictible memory access patern. All the parameters needed are passed to this class by the StructuredAggregationFactory class.
