void VCAMRPoissonOp2Factory::define	(	const ProblemDomain &	a_coarseDomain,
		const Vector< DisjointBoxLayout > &	a_grids,
		const Vector< int > &	a_refRatios,
		const Real &	a_coarsedx,
		BCHolder	a_bc,
		const Real &	a_alpha,

	)

a_coarseDomain is the domain at the coarsest level. a_grids is the AMR hierarchy. a_refRatios are the refinement ratios between levels. The ratio lives with the coarser level so a_refRatios[ilev] is the ratio between ilev and ilev+1 a_coarseDx is the grid spacing at the coarsest level. a_bc holds the boundary conditions. a_alpha is the identity constant coefficient a_beta is the laplacian constant coefficient. a_aCoef is the identity spatially varying coefficient a_bCoef is the laplacian spatially varying coefficient.

void VCAMRPoissonOp2Factory::define	(	const ProblemDomain &	a_coarseDomain,
		const Vector< DisjointBoxLayout > &	a_grids,
		const Vector< int > &	a_refRatios,

		BCHolder	a_bc,
		const IntVect &	a_ghostVect
	)

Defines a factory for VCAMRPoissonOp2 which allows the operators to allocate their own coefficient data. $\alpha$ and $\beta$ coefficients are initialized to 1.

Parameters:

	a_coarseDomain	The domain at the coarsest level.
	a_grids	The disjoint box layouts for the various refinement levels.
	a_refRatios	The refinement ratios between levels.
	a_coarsedx	The grid spacing at the coarsest level.
	a_bc	The boundary condition imposed on the solution.
	a_ghostVect	The ghost stencil to use in the created coefficient data.

virtual MGLevelOp<LevelData<FArrayBox> >* VCAMRPoissonOp2Factory::MGnewOp	(	const ProblemDomain &	a_FineindexSpace,
		int	a_depth,
		bool	a_homoOnly = `true`
	)			`[virtual]`

Create an operator at an index space = coarsen(a_fineIndexSpace, 2^a_depth) Return NULL if no such Multigrid level can be created at this a_depth. If a_homoOnly = true, then only homogeneous boundary conditions will be needed.

Implements MGLevelOpFactory< LevelData< FArrayBox > >.
