Detailed Description

Factory class for making variable-coefficient Helmholtz operators.

Note: This factory is designed for making EBHelmholtzOps which have time-independent coefficients. If you need new coefficients you better set up multigrid again.; This factory is designed without time-dependence in BCs. Time-dependent BCs are still doable by letting the boundary condition classes carry a reference to an externally updated time.

Full constructor.

Parameters

[in]	a_dataLocation	Assumed data centering
[in]	a_alpha	alpha-coefficient in Helmholtz operator.
[in]	a_beta	beta-coefficient in Helmholtz operator.
[in]	a_probLo	Lower-left corner of domain
[in]	a_amrInterpolators	Interpolator objects between AMR levels.
[in]	a_amrCoarseners	Conservative coarseners between AMR levels.
[in]	a_amrFluxRegisters	Flux registers between AMR levels.
[in]	a_amrResolutions	Grid resolutions for AMR levels.
[in]	a_amrAcoef	A-coefficient in Helmholtz operator.
[in]	a_amrBcoef	B-coefficient in Helmholtz operator.
[in]	a_amrBcoefIrreg	B-coefficient in Helmholtz operator. This one is defined on EB faces.
[in]	a_domainBCFactory	Factory class for making domain BC objects.
[in]	a_ebbcFactory	Factory class for making BC objects for EB boundary conditions.
[in]	a_ghostPhi	Number of ghost cells in solution vector.
[in]	a_ghostRhs	Number of ghost cells in right-hand side.
[in]	a_relaxationMethod	Relaxation method.
[in]	a_bottomDomain	Coarsest domain on which we run multigrid. Must be a coarsening of the AMR problem domains.
[in]	a_deeperLevelGrids	Optional object in case you want to pre-define the deeper multigrid levels.

Note: a_deeperLevelGrids exists because the default behavior in this factory is to use direct coarsening for deeper AMR levels. However, this can prevent reaching "deep enough" into the multigrid hierarchy if you use small boxes (e.g. 16^3). So, a_deeperLevelGrids provide an option for using aggregation. The first entry a_deeperLevelGrids[0] should be a a factor 2 coarsening of the coarsest AMR level.; This operator is for time-independent a- and b-coefficients.
