Detailed Description

A simple strategy for use with LU2x2PreconditionerFactory, that offers static objects for inv(F) and inv(S)

This is a simple startegy for a LU2x2PreconditionerFactory it simply returns statically set RCP pointers to the passed in inv(F) and inv(Schur) operators. Note this will not permit efficient implementations when the preconditioner has to be rebuilt

Constructor & Destructor Documentation

Teko::StaticLU2x2Strategy::StaticLU2x2Strategy	(	const Teko::LinearOp &	hInvA00,
		const Teko::LinearOp &	tInvA00,
		const Teko::LinearOp &	invS
	)		`[inline]`

Constructor that takes the static $A_{00}^{-1}$ and $S^{-1}$ objects.

Parameters:

[in]	hInvA00	Inverse of $\hat{A}_{00}$ in the source matrix.
[in]	tInvA00	Inverse of $\tilde{A}_{00}$ in the source matrix.
[in]	invS	Inverse of the Schur complement of the source matrix.
