Detailed Description

A wrapper class for an identity preconditioner for Trilinos matrices.

Author: Bruno Turcksin, 2013; extension for full compatibility with LinearOperator class: Jean-Paul Pelteret, 2016

Definition at line 1873 of file trilinos_precondition.h.

Member Function Documentation

void PreconditionIdentity::initialize	(	const SparseMatrix &	matrix,
		const AdditionalData &	additional_data = `AdditionalData()`
	)

The matrix argument is ignored and here just for compatibility with more complex preconditioners.

Note: This function must be called when this preconditioner is to be wrapped in a LinearOperator without an exemplar materix.

Definition at line 721 of file trilinos_precondition.cc.

void PreconditionIdentity::vmult	(	MPI::Vector &	dst,
		const MPI::Vector &	src
	)		const

overridevirtual

Apply the preconditioner, i.e., dst = src.

Reimplemented from TrilinosWrappers::PreconditionBase.

Definition at line 765 of file trilinos_precondition.cc.

void PreconditionIdentity::Tvmult	(	MPI::Vector &	dst,
		const MPI::Vector &	src
	)		const

overridevirtual

Apply the transport conditioner, i.e., dst = src.

Reimplemented from TrilinosWrappers::PreconditionBase.

Definition at line 771 of file trilinos_precondition.cc.

void PreconditionIdentity::vmult	(	::Vector< double > &	dst,
		const ::Vector< double > &	src
	)		const

overridevirtual

Apply the preconditioner on deal.II data structures instead of the ones provided in the Trilinos wrapper class, i.e., dst = src.

Reimplemented from TrilinosWrappers::PreconditionBase.

Definition at line 777 of file trilinos_precondition.cc.

void PreconditionIdentity::Tvmult	(	::Vector< double > &	dst,
		const ::Vector< double > &	src
	)		const

overridevirtual

Apply the transpose preconditioner on deal.II data structures instead of the ones provided in the Trilinos wrapper class, i.e. dst = src.

Reimplemented from TrilinosWrappers::PreconditionBase.

Definition at line 784 of file trilinos_precondition.cc.

void TrilinosWrappers::PreconditionIdentity::vmult	(	LinearAlgebra::distributed::Vector< double > &	dst,
		const ::LinearAlgebra::distributed::Vector< double > &	src
	)		const

override

Apply the preconditioner on deal.II parallel data structures instead of the ones provided in the Trilinos wrapper class, i.e., dst = src.

void TrilinosWrappers::PreconditionIdentity::Tvmult	(	LinearAlgebra::distributed::Vector< double > &	dst,
		const ::LinearAlgebra::distributed::Vector< double > &	src
	)		const

override

Apply the transpose preconditioner on deal.II parallel data structures instead of the ones provided in the Trilinos wrapper class, i.e., dst = src.
