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

Member Function Documentation

initialize()

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 717 of file trilinos_precondition.cc.

vmult() [1/3]

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

virtual

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

Reimplemented from TrilinosWrappers::PreconditionBase.

Definition at line 760 of file trilinos_precondition.cc.

Tvmult() [1/3]

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

virtual

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

Reimplemented from TrilinosWrappers::PreconditionBase.

Definition at line 767 of file trilinos_precondition.cc.

vmult() [2/3]

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

virtual

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 774 of file trilinos_precondition.cc.

Tvmult() [2/3]

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

virtual

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 781 of file trilinos_precondition.cc.

vmult() [3/3]

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

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

Tvmult() [3/3]

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

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