Detailed Description

class to encapsulate CF info for quadratic interpolation

QuadCFStencil is a wrapper around a bunch of things that allow LevelOp to do coarse-fine interpolation on a particular face of a grid.

Member Function Documentation

Real QuadCFStencil::computeFirstDerivative (  const BaseFab< Real > &    a_phic, int    a_derivdir, int    a_ivar, const IntVect &    a_ivin, Real    a_dx )  const

compute first derivative in devdir_a direction at coarse point a_ivin Uses centered finite diff approximation if ivs_standard_m.contains(a_ivin ). Otherwise, it uses the stencil from firstd_m Asserts that a_derivdir != direction of face

Real QuadCFStencil::computeMixedDerivative (  const BaseFab< Real > &    a_phic, int    a_ivar, const IntVect &    a_ivin, Real    a_dx )  const

compute mixed derivative (direction is unambiguous. x and y are the two directions tangential to face) at coarse point a_ivin. \ In two dimensions, always returns 0. \ Uses centered finite diff approximation if ivs_standard_m.contains(a_ivin ). It uses the stencil from mixed_sten_m.\ Returns 0 if SpaceDim != 3

Real QuadCFStencil::computeSecondDerivative (  const BaseFab< Real > &    a_phic, int    a_derivdir, int    a_ivar, const IntVect &    a_ivin, Real    a_dx )  const

{\bf Derivative functions} compute second derivative in devdir_a direction at coarse point a_ivin Uses centered finite diff approximation if ivs_standard_m.contains(a_ivin ). Otherwise, it uses the stencil from second_m Asserts that a_derivdir != direction of face

void QuadCFStencil::define (  const ProblemDomain &    a_fine_domain, const Box &    a_grid, const DisjointBoxLayout &    a_fineBoxes, const DisjointBoxLayout &    a_coarBoxes, int    a_refRatio, int    a_direction, Side::LoHiSide    a_hiorlo )

void QuadCFStencil::define (  const Box &    a_fine_domain, const Box &    a_grid, const DisjointBoxLayout &    a_fineBoxes, const DisjointBoxLayout &    a_coarBoxes, int    a_refRatio, int    a_direction, Side::LoHiSide    a_hiorlo )

const IntVectSet& QuadCFStencil::getCoarIVS (    )  const [inline]

get coarse intvects that underly fiinterpivs. This will be empty if isEmpty() returns true

const IntVectSet& QuadCFStencil::getFineIVS (    )  const [inline]

get fine intvects which need to be interpolated \ This will be empty if isEmpty() returns true

bool QuadCFStencil::isDefined (    )  const

{\bf Access functions} has full define function been called? return true if so

bool QuadCFStencil::isEmpty (    )  const [inline]

are there any interpolation points? \ returns false if so.
