Detailed Description

Class to enforce boundary conditions.

This class holds a domain's worth of FaceNodeBCs, one for each face. The user adds a FaceNodeBC-derived class for each face to enforce boundary conditions.\ If the solution is phi and the face normal direction is x, the boundary conditions at a face are expressed as A*dphi/dx + B*phi = C. \ The class derived from FaceNodeBC provides a function to to fill A and B and C. DomainNodeBC calls this function and fills the boundary nodes appropriately.
