Detailed Description

template<class Scalar = SmootherPrototype<>::scalar_type, class LocalOrdinal = typename SmootherPrototype<Scalar>::local_ordinal_type, class GlobalOrdinal = typename SmootherPrototype<Scalar, LocalOrdinal>::global_ordinal_type, class Node = typename SmootherPrototype<Scalar, LocalOrdinal, GlobalOrdinal>::node_type>
class MueLu::BelosSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Class that encapsulates Belos smoothers.

This class creates an Belos preconditioner factory. The factory creates a smoother based on the type and ParameterList passed into the constructor. See the constructor for more information.

Member Function Documentation

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::BelosSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::SetParameterList ( const Teuchos::ParameterList paramList)
virtual

Set parameters from a parameter list and return with default values.

Reimplemented from MueLu::ParameterListAcceptorImpl.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >
void MueLu::BelosSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Setup ( Level currentLevel)
virtual

Set up the smoother.

This creates the underlying Belos smoother object, copies any parameter list options supplied to the constructor to the Belos object, and computes the preconditioner.

Implements MueLu::SmootherPrototype< Scalar, LocalOrdinal, GlobalOrdinal, Node >.

void MueLu::BelosSmoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Apply ( MultiVector &  X,

bool  InitialGuessIsZero = false 
) const
virtual

Apply the preconditioner.

Solves the linear system AX=B using the constructed smoother.

Parameters
Xinitial guess
Bright-hand side
InitialGuessIsZero(optional) If false, some work can be avoided. Whether this actually saves any work depends on the underlying Belos implementation.
