Detailed Description

Pure base class to encapsulate level operations API for elliptic solvers.

LevelOp is a pure base class to encapsulate level operations API for elliptic solvers. All elliptic operators used by AMRSolver inherit the LevelOp interface.

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

constructors, destructors, defines

Coarse / Fine interpolation operator. Fill ghost cells of phi

Implemented in HelmholtzOp, and PoissonOp.

virtual void LevelOp::define (  const LevelOp *    opfine,
int    reftofine
)  [pure virtual]
 

Full define function. define from finer levelop. reftofine is the refinement ratio to get from *this opfine

Implemented in HelmholtzOp, and PoissonOp.

virtual void LevelOp::define (  const DisjointBoxLayout &    Ba,
const DisjointBoxLayout *    base_ba,
Real    DxLevel,
int    refratio,
const ProblemDomain &    domf,
bool    homogeneousOnly,
int    ncomp = 1
)  [pure virtual]
 

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

Implemented in HelmholtzOp, and PoissonOp.

virtual void LevelOp::define (  const DisjointBoxLayout &    Ba,
const DisjointBoxLayout *    base_ba,
Real    DxLevel,
int    refratio,
const Box &    domf,
bool    homogeneousOnly,
int    ncomp = 1
)  [pure virtual]
 

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

Implemented in HelmholtzOp, and PoissonOp.

virtual void LevelOp::getFlux (  FArrayBox &    flux,
const FArrayBox &    data,
const DataIndex &    a_datInd,
int    dir
)  [pure virtual]
 

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.

Implemented in HelmholtzOp, and PoissonOp.

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

homogeneous coarse/fine interpolation operator

Implemented in HelmholtzOp, and PoissonOp.

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

Implemented in VelocityPoissonOp, HelmholtzOp, and PoissonOp.

virtual void LevelOp::levelPreconditioner (  LevelData< FArrayBox > &    a_phihat,
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 HelmholtzOp, and PoissonOp.

virtual LevelOp* LevelOp::new_levelop (    )  const [pure virtual]
 

this gets around the "no virtual constructor" rule

Implemented in VelocityPoissonOp, HelmholtzOp, and PoissonOp.

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

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

Implemented in HelmholtzOp, and PoissonOp.
