Documentation

this class contains stuff to solve div (grad phi) = rhs
virtual LevelOp * new_levelop () const
virtual constructor workaround

void define ( const DisjointBoxLayout & Ba, const DisjointBoxLayout * base_ba, Real DxLevel, int refratio, const Box& domf, bool a_homogeneousOnly=false, int ncomp = 1)
Full define function. makes all coarse-fine information and sets internal variables

void define ( const DisjointBoxLayout & Ba, const DisjointBoxLayout * base_ba, Real DxLevel, int refratio, const ProblemDomain & domf, bool a_homogeneousOnly=false, int ncomp = 1)
Full define function. makes all coarse-fine information and sets internal variables

void define ( const LevelOp * opfine, int refratio)
Full define function. define from finer levelop.

void 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.

virtual void levelPreconditioner ( LevelData< FArrayBox >& a_phihat, const LevelData< FArrayBox >& a_rhshat )
apply preconditioning to the solution on this level. Given rhshat, returns phihat from M(phihat) = rhshat

void applyOpI ( LevelData< FArrayBox >& a_phi, const LevelData< FArrayBox >* a_phiCoarse, LevelData< FArrayBox >& a_LOfPhi)
Evaluate Operator, inhomogeneous C/F boundary conditions. and inhomogeneous phys boundary conditions

void applyOpIcfHphys ( LevelData< FArrayBox >& a_phi, const LevelData< FArrayBox >* a_phiCoarse, LevelData< FArrayBox >& a_LOfPhi)
Evaluate Operator, inhomogeneous C/F boundary conditions. with homogeneous physical boundary conditions

void applyOpH ( LevelData< FArrayBox >& a_phi, LevelData< FArrayBox >& a_LOfPhi)
Evaluate Operator, homogeneous C/F boundary conditions. and homogeneous physical boundary conditions

void CFInterp (LevelData< FArrayBox >& a_phi, const LevelData< FArrayBox >& a_phiCoarse )
Coarse / Fine interpolation operator.

void applyOpHcfIphys ( LevelData< FArrayBox >& a_phi, LevelData< FArrayBox >& a_lOfPhi)
Evaluate Operator, homogeneous C/F boundary conditions. with inhomogeneous physical boundary conditions

void homogeneousCFInterp (LevelData< FArrayBox >& a_phi)
homogeneous coarse/fine interpolation operator

void homogeneousCFInterp (LevelData< FArrayBox >& a_phif, const DataIndex& a_datInd, int a_idir, Side::LoHiSide a_hiorlo)
does homogeneous coarse/fine interpolation

void 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 getFlux ( FArrayBox & flux, 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.
