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.

int    a_derivdir,

)  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

{\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
