Detailed Description

template<class Scalar = DefaultScalar, class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::CoarseMapFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Factory for generating coarse level map. Used by TentativePFactory.

Factory is used by TentativePFactory to generate the coarse level map (=domain map) of the prolongation operator. The number of DOFs is calculated by the following formula

\[ n_{Aggs}\cdot d_{blocksize} \]

where \( n_{Aggs} \) denotes the number of aggregates (generated by the AggregationFactory) and \( d_{blocksize}\) denotes the number of DOFs per node on the coarse level. For determing the blocksize, the CoarseMapFactory supports strided map information. Per default stridedBlockId is -1 and the number of nullspace vectors (from "Nullspace" ) is used. Otherwise, the block size is calculated using the striding information.

By setting the "Domain GID offsets" parameter, we can specify the GID offset manually for each level. If the number of entries in that list is smaller than the number of levels, we use the default offset 0 for the remaining coarse levels.

Input/output

User parameters of this factory

Parameter	type	default	validated	requested	description
Aggregates	Factory	null	*	*	Generating factory for aggregates. We basically need only the number of aggregates in this factory.
Nullspace	Factory	null	*	*	Generating factory of the fine nullspace vectors (of type "MultiVector"). In the default case the same instance of the TentativePFactory is also the generating factory for the null space vectors (on the next coarser levels). Therefore, it is recommended to declare the TentativePFactory to be the generating factory of the "Nullspace" variable globally using the FactoryManager object! For defining the near null space vectors on the finest level one should use the NullspaceFactory.
Striding info	std::string	{}	*		String containing the striding information, e.g. {2,1} for a fixed block size of 3 with sub blocks of size 2 and 1 in each node.
Strided block id	LocalOrdinal	-1	*		Strided block id in strided information vector or -1 (=default) for the full block information.
Domain GID offsets	std::string	{0}	*		String describing a std::vector with offsets for GIDs for each level. If no offset GID value is given for the level we use 0 as default.

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 GetValidParameters() ).
The * in the requested column states that the data is requested as input with all dependencies (see DeclareInput() ).

Note: To auto-compute the Domain GID offset on each level, consider to use the BlockedCoarseMapFactory .
