Detailed Description

template<typename LAI>
class geosx::SeparateComponentPreconditioner< LAI >

Separate component filter implemented as a compound preconditioner.

Template Parameters

LAI	linear algebra interface to use

Definition at line 34 of file SeparateComponentPreconditioner.hpp.

Constructor & Destructor Documentation

◆ SeparateComponentPreconditioner()

template<typename LAI >

geosx::SeparateComponentPreconditioner< LAI >::SeparateComponentPreconditioner	(	localIndex const	numComp,
		std::unique_ptr< PreconditionerBase< LAI > >	precond
	)

Constructor.

Parameters

numComp	number of components in the field
precond	the actual preconditioner to apply to filtered matrix (ownership transferred)

Member Function Documentation

◆ apply()

template<typename LAI >

virtual void geosx::SeparateComponentPreconditioner< LAI >::apply	(	Vector const &	src,
		Vector &	dst
	)		const

overridevirtual

Apply operator to a vector.

Parameters

src	Input vector (x).
dst	Output vector (b).

Warning: src and dst cannot alias the same vector.

◆ clear()

template<typename LAI >

virtual void geosx::SeparateComponentPreconditioner< LAI >::clear ( )

overridevirtual

Clean up the preconditioner setup.

Releases memory used and allows the matrix to be deleted cleanly. This method should be called before the matrix used to compute the preconditioner goes out of scope or is re-created. Some implementations require the matrix to outlive the preconditioner (for example, Trilinos/ML may crash the program if deleted after the matrix).

Note: Should be properly overridden in derived classes, which may call this method.

Reimplemented from geosx::PreconditionerBase< LAI >.

◆ compute()

template<typename LAI >

virtual void geosx::SeparateComponentPreconditioner< LAI >::compute	(	Matrix const &	mat,
		DofManager const &	dofManager
	)

overridevirtual

Compute the preconditioner from a matrix.

Parameters

mat	the matrix to precondition
dofManager	the Degree-of-Freedom manager associated with matrix

Reimplemented from geosx::PreconditionerBase< LAI >.

◆ getNestedPrecond()

template<typename LAI >

PreconditionerBase< LAI > const& geosx::SeparateComponentPreconditioner< LAI >::getNestedPrecond ( ) const

inline

Access to the nested preconditioner.

Returns: reference to the preconditioner passed at construction

Definition at line 88 of file SeparateComponentPreconditioner.hpp.

◆ getPrecondMatrix()

template<typename LAI >

Matrix const& geosx::SeparateComponentPreconditioner< LAI >::getPrecondMatrix ( ) const

inline

Access the preconditioning matrix.

Returns: reference to the filtered matrix

Definition at line 79 of file SeparateComponentPreconditioner.hpp.
