void RegPoissonOp::applyOpHcfIphys (  LevelData< FArrayBox > &    a_phi, LevelData< FArrayBox > &    a_LOfPhi )  [virtual]

Evaluate Operator, homogeneous C/F boundary conditions. inhomogeneous domain boundary conditions Implements GenAMRLevelMGOp< LevelData< FArrayBox > >.

void RegPoissonOp::applyOpI (  LevelData< FArrayBox > &    a_phi, const LevelData< FArrayBox > *    a_phicPtr, LevelData< FArrayBox > &    a_LOfPhi )  [virtual]

Evaluate Operator, inhomogeneous C/F boundary conditions and phys boundary conditions. Implements GenAMRLevelMGOp< LevelData< FArrayBox > >.

void RegPoissonOp::applyOpIcfHphys (  LevelData< FArrayBox > &    a_phi, const LevelData< FArrayBox > *    a_phicPtr, LevelData< FArrayBox > &    a_LOfPhi )  [virtual]

Evaluate Operator, inhomogeneous C/F boundary conditions. homogeneous domain boundary conditions. Implements GenAMRLevelMGOp< LevelData< FArrayBox > >.

void RegPoissonOp::bottomSmoother (  LevelData< FArrayBox > &    a_phi, const LevelData< FArrayBox > &    a_rhs )

This does a GSRB Pre/Conditioned BiCGStab on a level for the bottom solver.

void RegPoissonOp::CFInterp (  LevelData< FArrayBox > &    a_phif, const LevelData< FArrayBox > &    a_phic )  [virtual]

Coarse / Fine interpolation operator. fills ghost cells of phi. Implements GenLevelOp< FArrayBox >.

void RegPoissonOp::clearMemory (    )  [private]

void RegPoissonOp::define (  const RegLevelOp *    a_opfinePtr, int    a_refToFine )  [virtual]

Full define function. define from finer levelop. Implements RegLevelOp.

void RegPoissonOp::define (  const DisjointBoxLayout &    a_grids, const DisjointBoxLayout *    a_baseBAPtr, Real    a_dxLevel, int    a_refRatio, const ProblemDomain &    a_domain, bool    a_homogeneousOnly = false, int    a_ncomp = 1 )  [virtual]

Full define function. makes all coarse-fine information and sets internal variables Implements RegLevelOp.

void RegPoissonOp::define (  const DisjointBoxLayout &    a_grids, const DisjointBoxLayout *    a_baseBAPtr, Real    a_dxLevel, int    a_refRatio, const Box &    a_domain, bool    a_homogeneousOnly = false, int    a_ncomp = 1 )  [virtual]

void RegPoissonOp::getFlux (  FArrayBox &    a_fineFlux, const FArrayBox &    a_data, const DataIndex &    a_datInd, int    a_dir )

get flux( == flux at THIS level) 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.

void RegPoissonOp::homogeneousCFInterp (  LevelData< FArrayBox > &    a_phif, const DataIndex &    a_datInd, int    a_idir, Side::LoHiSide    a_hiorlo )  [virtual]

does homogeneous coarse/fine interpolation for one grid Implements GenLevelOp< FArrayBox >.

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

homogeneous coarse/fine interpolation operator Implements GenLevelOp< FArrayBox >.

void RegPoissonOp::interpOnIVSHomo (  LevelData< FArrayBox > &    a_phif, const DataIndex &    a_datInd, const int    a_idir, const Side::LoHiSide    a_hiorlo, const IntVectSet &    a_interpIVS )  [private]

virtual bool RegPoissonOp::isDefined (    )  const [virtual]

Implements RegLevelOp.

void RegPoissonOp::levelGSRB (  LevelData< FArrayBox > &    a_phi, const LevelData< FArrayBox > &    a_rhs )  [private]

virtual void RegPoissonOp::levelPreconditioner (  LevelData< FArrayBox > &    a_phihat, const LevelData< FArrayBox > &    a_rhshat )  [virtual]

apply preconditioning to the solution on this level. Given rhshat, returns phihat from M(phihat) = rhshat Implements GenLevelOp< FArrayBox >.

virtual RegPoissonOp* RegPoissonOp::newOp (    )  const [virtual]

virtual constructor workaround Implements RegLevelOp.

void RegPoissonOp::setBottomSmoother (  const GenBaseBottomSmoother< LevelData< FArrayBox > > &    a_bottomSmoother )

void RegPoissonOp::setDefaultValues (    )  [private]

void RegPoissonOp::setDomainGhostBC (  const RegDomainGhostBC &    a_dombcin )

void RegPoissonOp::smooth (  LevelData< FArrayBox > &    a_phi, const LevelData< FArrayBox > &    a_rhs )

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