Detailed Description

A simple class that takes a vector of the InverseFactory objects and pairs each with the diagonal element of the block matrix. This provides the operators needed to use Gauss-Seidel or Jacobi.

Constructor & Destructor Documentation

Teko::InvFactoryDiagStrategy::InvFactoryDiagStrategy ( const Teuchos::RCP< InverseFactory > & factory )

Constructor accepting a single inverse factory that will be used to invert all diagonal blocks.

Parameters

[in] factory Factory to be used to invert each diagonal block.

Definition at line 51 of file Teko_BlockInvDiagonalStrategy.cpp.

Teko::InvFactoryDiagStrategy::InvFactoryDiagStrategy	(	const std::vector< Teuchos::RCP< InverseFactory > > &	factories,
		const Teuchos::RCP< InverseFactory > &	defaultFact = `Teuchos::null`
	)

Constructor that lets the inverse of each block be set individually.

Parameters

[in]	factories	A vector of `InverseFactory` objects which should be the same length as the number of diagonal blocks.
[in]	defaultFact	The default factory to use if none is specified.

void Teko::InvFactoryDiagStrategy::getInvD	(	const BlockedLinearOp &	A,
		BlockPreconditionerState &	state,
		std::vector< LinearOp > &	invDiag
	)		const

virtual

returns an (approximate) inverse of the diagonal blocks of A where A is closely related to the original source for invD0 and invD1

Parameters

[in]	A	Operator to extract the block diagonals from.
[in]	state	State object for this operator.
[in,out]	invDiag	Vector eventually containing the inverse operators

returns an (approximate) inverse of the diagonal blocks of A where A is closely related to the original source for invD0 and invD1
