Detailed Description

This class applies an operator as a smoother. The main idea being that a residual is used and corrected to get a Gauss-Seidel like method.

Member Function Documentation

◆ range()

virtual VectorSpace Teko::SmootherLinearOp::range ( ) const
inlinevirtual

Range space of this operator.

Implements Teko::ImplicitLinearOp.

Definition at line 67 of file Teko_SmootherPreconditionerFactory.hpp.

◆ domain()

virtual VectorSpace Teko::SmootherLinearOp::domain ( ) const
inlinevirtual

Domain space of this operator.

Implements Teko::ImplicitLinearOp.

Definition at line 71 of file Teko_SmootherPreconditionerFactory.hpp.

◆ implicitApply()

void Teko::SmootherLinearOp::implicitApply ( const MultiVector & x,
MultiVector & y,
const double alpha = 1.0,
const double beta = 0.0 ) const
virtual

Perform a matrix vector multiply with this implicitly defined blocked operator.

The apply function takes one vector as input and applies a linear operator. The result is returned in $y$. If this operator is reprsented as $M$ then $ y = \alpha M x + \beta y $

Parameters
[in]x
[in,out]y
[in]alpha(default=1)
[in]beta(default=0)

Implements Teko::ImplicitLinearOp.

Definition at line 86 of file Teko_SmootherPreconditionerFactory.cpp.

◆ setRequestHandler()

void Teko::SmootherLinearOp::setRequestHandler ( const Teuchos::RCP< RequestHandler > & rh)
virtual

Set the request handler with pointers to the appropriate callbacks.

Implements Teko::RequestHandlerContainer.

Definition at line 130 of file Teko_SmootherPreconditionerFactory.cpp.

◆ getRequestHandler()

Teuchos::RCP< RequestHandler > Teko::SmootherLinearOp::getRequestHandler ( ) const
virtual

Get the request handler with pointers to the appropriate callbacks.

Implements Teko::RequestHandlerContainer.

Definition at line 137 of file Teko_SmootherPreconditionerFactory.cpp.
