Detailed Description

Uses a scaled identity operator as the approximate inverse. This is a last resort!

Constructor & Destructor Documentation

Teko::IdentityPreconditionerFactory::IdentityPreconditionerFactory ( )

Member Function Documentation

LinearOp Teko::IdentityPreconditionerFactory::buildPreconditionerOperator	(	LinearOp &	lo,
		PreconditionerState &	state
	)		const

virtual

Create the Identity preconditioner operator.

This method breaks apart the BlockLinearOp and builds a block diagonal preconditioner. The inverse of the diagonals are specified by the BlockInvDiagonalStrategy object.

Implements Teko::PreconditionerFactory.

void Teko::IdentityPreconditionerFactory::initializeFromParameterList ( const Teuchos::ParameterList & pl )

protectedvirtual

Initialize from a parameter list.

Reimplemented from Teko::PreconditionerFactory.
