Detailed Description

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

Factory for extracting a zero block from a BlockedCrsMatrix.

This is a very simple class to access a single matrix block in a blocked operator A, where the matrix block of interest is an actual zero block (as e.g. in saddle point systems).

◆ GetValidParameterList()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

RCP< const ParameterList > MueLu::ZeroSubBlockAFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::GetValidParameterList ( ) const

overridevirtual

Input.

Reimplemented from MueLu::Factory.

Definition at line 27 of file MueLu_ZeroSubBlockAFactory_def.hpp.

◆ DeclareInput()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

void MueLu::ZeroSubBlockAFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::DeclareInput ( Level & currentLevel ) const

overridevirtual

Specifies the data that this class needs, and the factories that generate that data.

If the Build method of this class requires some data, but the generating factory is not specified in DeclareInput, then this class will fall back to the settings in FactoryManager.

Implements MueLu::SingleLevelFactoryBase.

◆ Build()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

void MueLu::ZeroSubBlockAFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Build ( Level & currentLevel ) const

overridevirtual

Build a zero sub-block object with this factory.

Create a zero sub block matrix, that fits into a given blocked crs operator.

Strided or block information is extracted in the following way: 1) first check whether the corresponding sub maps are strided If yes, use the fixed block size and strided block id 2) If no, get the full map of the map extractors. Check whether the full map is strided. If yes, use the strided information of the full map and build partial (strided) maps with it If no, throw an exception

For blocked operators with block maps one should use the striding information from the sub maps. For strided operators, the striding information of the full map is the best choice.

Implements MueLu::SingleLevelFactoryBase.
