Full define function.

Define from finer levelop. reftofine is the refinement ratio to get from this LevelOp to opfine

Parameters:
a_opfine  Finer levelOp from which this will be defined
a_reftoFine  Amount this LevelOp will be coarser than opfine

Implemented in HelmholtzOp, and PoissonOp.

Full define function.

Makes all coarse-fine information and sets internal variables

Parameters:
a_grids  Grids at this level
a_baseBAPtr  Coarser-level grids
a_dxLevel  Cell spacing at this level
a_refRatio  Refinement ratio btwn this level and coarser level

Get flux at this level in the direction dir over the given Box.

The fluxes live on the cell faces with direction dir. Fluxes are computed for all interior edges of data. The flux fab is resized inside the routine.

Parameters:
a_fineFlux  Face-centered Fluxes in direction dir (resized in function)
a_data  Cell-centered box over which fluxes will be computed
a_datInd  Data index of grid where flux is located
a_dir  Direction of fluxes to be computed

Implemented in HelmholtzOp, and PoissonOp.

virtual void LevelOp::homogeneousCFInterp (  LevelData< FArrayBox > &  a_phif  )  [pure virtual]
 

Homogeneous coarse/fine interpolation operator.

Implemented in HelmholtzOp, and PoissonOp.

virtual bool LevelOp::isDefined (   )  const [pure virtual]
 

Has this object been fully defined?

const LevelData< FArrayBox > &  a_rhshat
)  [pure virtual]
 

Apply preconditioning to the solution on this level.

Given rhshat, returns phihat from M(phihat) = rhshat

Implemented in VelocityPoissonOp, HelmholtzOp, and PoissonOp.

virtual void LevelOp::setConvergenceMetric (  Real  a_metric,
int  a_comp
)  [pure virtual]
 

set the convergence metrics (if appropriate) for this problem

If this LevelOp is being used in the context of a solve, we may wish to set a metric against which to define convergence (for example, the norm of the RHS). In many cases, this will simply be a pass-through to a bottom solver.

Implemented in HelmholtzOp, and PoissonOp.

virtual void LevelOp::smooth (  LevelData< FArrayBox > &  a_phi,
const LevelData< FArrayBox > &  a_rhs
)  [pure virtual]
 

Smoother.

Assumes that problem has already been put in residual correction form, so that C/F boundary conditions are homogeneous.

Parameters:
a_phi  Current guess at solution
a_rhs  Right-hand side of problem we're solving

Implemented in HelmholtzOp, and PoissonOp.
