EBStenVarCoef Class Reference

#include <EBStenVarCoef.H>

List of all members.


Detailed Description

EBStencil variant specifically for the needs of single-level variable coefficent elliptic operators. There is only one way to make it. Everyone has to have the same number of ghost cells. There is only one way to use it. If you want something more flexible, use EBStencil.
