If you are approaching this operator from this interface, consider backing away and using EBPoissonOpFactory to generate these objects. Really. a_eblg, : grid at this level \ a_eblgCoarMG, : grid at intermediate multigrid level \ a_domainBC, : domain boundary conditions at this level \ a_ebBC: eb boundary conditions at this level \ a_dx: grid spacing at this level \ a_origin: offset to lowest corner of the domain \ a_hasCoarserMG: true if there is a coarser MultiGrid level. \ a_preCondIters: number of iterations to do for pre-conditioning \ a_relaxType: 0 means point Jacobi, 1 is Gauss-Seidel. \ a_orderEB: 0 to not do flux interpolation at cut faces. \ a_alpha: coefficent of identity \ a_beta: coefficient of laplacian.\ a_ghostCellsPhi: Number of ghost cells in phi, correction (typically one)\ a_ghostCellsRhs: Number of ghost cells in RHS, residual, lphi (typically zero)\ Ghost cell arguments are there for caching reasons. Once you set them, an error is thrown if you send in data that does not match.

In the context of solving L(phi) = rhs, set a_lhs = L(a_phi). If a_homogeneous is true, evaluate the operator using homogeneous boundary conditions.

virtual void EBPoissonOp::create ( LevelData< EBCellFAB > &  a_lhs,
const LevelData< EBCellFAB > &  a_rhs

const LevelData< EBCellFAB > &  a_fine,
bool  ghosted 
) [virtual]

Create a coarsened (by two) version of the input data. This does not include averaging the data. So if a_fine is over a Box of (0, 0, 0) (63, 63, 63), a_fine should be over a Box (0, 0, 0) (31, 31, 31).

virtual void EBPoissonOp::relax ( LevelData< EBCellFAB > &  a_correction,
const LevelData< EBCellFAB > &  a_residual,
int  a_iterations 
) [virtual]

Use your relaxtion operator to remove the high frequency wave numbers from the correction so that it may be averaged to a coarser refinement. A point relaxtion scheme, for example takes the form a_correction -= lambda*(L(a_correction) - a_residual).

Implements MGLevelOp< LevelData< EBCellFAB > >.
