Detailed Description

A block diagonal preconditioner.

The use must specify an iverse for each diagonal. If a specific integer is not specified, then the default "Inverse Type" is used.

<Parameter name="Type" type="string" value="Block Jacobi"/>
<Parameter name="Inverse Type" type="string" value="<Some Inverse Factory>"/>
<Parameter name="Inverse Type 1" type="string" value="<Some Inverse Factory>"/>
<Parameter name="Inverse Type 2" type="string" value="<Some Inverse Factory>"/>
<Parameter name="Inverse Type 3" type="string" value="<Some Inverse Factory>"/>
<Parameter name="Inverse Type 4" type="string" value="<Some Inverse Factory>"/>

Teko::JacobiPreconditionerFactory::JacobiPreconditionerFactory	(	const LinearOp &	invD0,
		const LinearOp &	invD1
	)

Construct a PreconditionerFactory assuming a specific block $2\times2$ matrix. This case is a simple one.

Member Function Documentation

LinearOp Teko::JacobiPreconditionerFactory::buildPreconditionerOperator	(	BlockedLinearOp &	blo,
		BlockPreconditionerState &	state
	)		const

virtual

Create the Jacobi 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::BlockPreconditionerFactory.
