Detailed Description

template<class LocalOrdinal, class GlobalOrdinal, class Node>
class MueLu::HybridAggregationFactory< LocalOrdinal, GlobalOrdinal, Node >

Factory for building aggregates on meshes partly structured and partly unstructured.

Factory for creating aggregates from partly structured grids. The hybrid aggregation method returns an aggregate structure used by prolongator factories.

Internally, each node has a status which can be one of the following:

Node status Meaning
READY Node is not aggregated and can be used for building a new aggregate or can be added to an existing aggregate.
AGGREGATED Node is aggregated.
IGNORED Node is not considered for aggregation (it may have been dropped or put into a singleton aggregate)
BOUNDARY Node is a Dirichlet boundary node (with one or more Dirichlet boundary conditions).
ONEPT The user forces the aggregation algorithm to treat the node as a singleton. Important: Do not forget to set aggregation: allow user-specified singletons to true! Otherwise Phase3 will just handle the ONEPT nodes and probably not build singletons

Input/output of HybridAggregationFactory

User parameters of HybridAggregationFactory

Parameter type default master.xml validated requested description
Graph Factory null * * Generating factory for variable 'Graph'
DofsPerNode Factory null * * Generating factory for variable 'DofsPerNode', usually the same as for 'Graph'
OnePt aggregate map name string * * Name of input map for single node aggregates (default=''). Makes only sense if the parameter 'aggregation: allow user-specified singletons' is set to true.
OnePt aggregate map factory Factory null * * Generating factory of (DOF) map for single node aggregates. Makes only sense if the parameter 'aggregation: allow user-specified singletons' is set to true.
aggregation: max agg size int see master.xml * * Maximum number of nodes per aggregate.
aggregation: min agg size int see master.xml * * Minimum number of nodes necessary to build a new aggregate.
aggregation: max selected neighbors int see master.xml * * Maximum number of neighbor nodes already in aggregate (needed in Phase1)
aggregation: ordering string "natural" * * Ordering of node aggregation (can be either "natural", "graph" or "random").
aggregation: enable phase 1 bool true * * Turn on/off phase 1 aggregation
aggregation: enable phase 2a bool true * * Turn on/off phase 2a aggregation
aggregation: enable phase 2b bool true * * Turn on/off phase 2b aggregation
aggregation: enable phase 3 bool true * * Turn on/off phase 3 aggregation
aggregation: preserve Dirichlet points bool false * * preserve Dirichlet points as singleton nodes (default=false, i.e., drop Dirichlet nodes during aggregation)
aggregation: allow user-specified singletons bool false * * Turn on/off OnePtAggregationAlgorithm (default=false)
aggregationRegionType Factory null * * Factory generating the type of aggregation to use on the region

The * in the master.xml column denotes that the parameter is defined in the master.xml file.
The * in the validated column means that the parameter is declared in the list of valid input parameters (see HybridAggregationFactory::GetValidParameters).
The * in the requested column states that the data is requested as input with all dependencies (see HybridAggregationFactory::DeclareInput).
