Detailed Description

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

Factory for building Smoothed Aggregation prolongators.

Input/output of SaPFactory

User parameters of SaPFactory

Parameter type default master.xml validated requested description
sa: damping factor double 1.33 * * Damping factor for smoothed aggregation transfer operators
sa: calculate eigenvalue estimate bool false * * Force calculation of eigenvalue estimate during prolongator smoothing
sa: eigenvalue estimate num iterations int 10 * * Number of power iterations to estimate max eigenvalue
A Factory null * * Generating factory of the matrix A used during the prolongator smoothing process
P Factory null * * Tentative prolongator factory (should be a TentativePFactory object). Note that if "P" is not provided the FactoryManager tries the factory which is generating the variable "Ptent" as input for "P". In the standard case using the default settings this is the non-smoothed tentative prolongation operator.

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

Variables provided by SaPFactory

After SaPFactory::Build the following data is available (if requested)

inline

Constructor. User can supply a factory for generating the tentative prolongator.

Definition at line 111 of file MueLu_SaPFactory_decl.hpp.

◆ ~SaPFactory()

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

Member Function Documentation

◆ GetValidParameterList()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
RCP< const ParameterList > MueLu::SaPFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::GetValidParameterList ( ) const
virtual

Return a const parameter list of valid parameters that setParameterList() will accept.

Also define the default values of parameters according to the input parameter list.

Reimplemented from MueLu::Factory.

Definition at line 67 of file MueLu_SaPFactory_def.hpp.

◆ DeclareInput()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::SaPFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::DeclareInput ( Level fineLevel,
Level coarseLevel 
) const
virtual

Input.

Implements MueLu::TwoLevelFactoryBase.

Definition at line 89 of file MueLu_SaPFactory_def.hpp.

◆ Build()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::SaPFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Build ( Level fineLevel,
Level coarseLevel 
) const
virtual

Build method.

Builds smoothed aggregation prolongator and returns it in coarseLevel. FIXME what does the return code mean (unclear in MueMat)?

Implements MueLu::TwoLevelFactoryBase.

Definition at line 100 of file MueLu_SaPFactory_def.hpp.

◆ BuildP()

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::SaPFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >::BuildP ( Level fineLevel,
Level coarseLevel 
) const
virtual

Abstract Build method.

Implements MueLu::PFactory.
