Member Function Documentation

void AMRPoissonOpFactory::define	(	const ProblemDomain &	a_coarseDomain,
		const Vector< DisjointBoxLayout > &	a_grids,
		const Vector< int > &	a_refRatios,
		const Real &	a_coarsedx,
		BCHolder	a_bc,
		Real	a_alpha = `0.0`,
		Real	a_beta = `1.0`
	)

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 coefficient a_beta is the laplacian coefficient.

void AMRPoissonOpFactory::define	(	const ProblemDomain &	a_domain,
		const DisjointBoxLayout &	a_grid,
		const Real &	a_dx,
		BCHolder	a_bc,
		int	a_maxDepth = `-1`,
		Real	a_alpha = `0.0`,
		Real	a_beta = `1.0`
	)

virtual MGLevelOp<LevelData<FArrayBox> >* AMRPoissonOpFactory::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 > >.
