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.

void DomainNodeBC::applyInhomogeneousBCs (  NodeFArrayBox &    a_state, const ProblemDomain &    a_domain, Real    a_dx )  const

Apply inhomogeneous boundary conditions on all sides of physical domain. {\bf Arguments:}\ a_state (modified): array on which boundary conditions will be set.\ a_domain (not modified): CELL-centered physical domain.\ a_dx (not modified): mesh spacing.\

bool DomainNodeBC::isBCDefined (  const int    a_dir, const Side::LoHiSide    a_side )  const [protected]

returns true if this NodeBC is defined
