Detailed Description

Class to enforce homogeneous Neumann boundary conditions.

BoxGhostBC class implentation to enforce homogeneous neumann boundary conditions Recall that BoxGhostBC is a class to encapsulate the operations of ghost-cell boundary conditions at a face. If the solution is phi and the face normal direction is x, the boundary conditions usually used can be expressed as A*phi + B*dphi/dx = C. For homogeneous Neumann BCs, A=C=0, B= 1 These functions are only meant to be called by DomainGhostBC
