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).
