Detailed Description

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

Constructor & Destructor Documentation

◆ IdentityPreconditionerFactory()

Teko::IdentityPreconditionerFactory::IdentityPreconditionerFactory ( )

Build an empty Identity preconditioner factory.

Build a Identity preconditioner factory from a parameter list

Member Function Documentation

◆ buildPreconditionerOperator()

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.
