Detailed Description
class MueLu::PreserveDirichletAggregationAlgorithm< LocalOrdinal, GlobalOrdinal, Node >
Builds one-to-one aggregates for all Dirichlet boundary nodes. For some applications this might be necessary. (default = off)
Idea
Handles Dirichlet boundary nodes with the state Boundary. Depending on the boolean parameter "aggregation: preserve Dirichlet points" one-to-one aggregates with singleton nodes are built for all Dirichlet boundary nodes or the aggregates are just ignored (default behavior). The state of all boundary nodes (state = Boundary) is set to ignored. That means, that these nodes are not considered for further aggregation in the later aggregation phases.
Parameters
| Parameter | Meaning |
|---|---|
| aggregation: preserve Dirichlet points | Boolean parameter stating whether Dirichlet boundary nodes shall be aggregated in singleton aggregates (default: false). |
Comments
Only nodes with state BOUNDARY are changed to IGNORED. No other nodes are touched.
