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

virtual void NeumannBC::fillBCValues (  FArrayBox &  a_neumfac, FArrayBox &  a_dircfac, FArrayBox &  a_inhmval, Real  a_dx, const ProblemDomain &  a_domain )  const [protected, virtual]

Fills coefficient arrays -- fills neumann factor with 1.0 and other two fields with 0.0. Implements BoxGhostBC.

virtual void NeumannBC::fillBCValues (  FArrayBox &  a_neumfac, FArrayBox &  a_dircfac, FArrayBox &  a_inhmval, Real  a_dx, const Box &  a_domain )  const [protected, virtual]

Fills coefficient arrays -- fills neumann factor with 1.0 and other two fields with 0.0. Implements BoxGhostBC.

BoxGhostBC* NeumannBC::new_boxghostbc (   )  const [protected, virtual]

Virtual constructor workaround. Implements BoxGhostBC.
