Detailed Description

A class to encapsulate the operations of boundary conditions.

FaceNodeBC is a class to encapsulate the operations of 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*dphi/dx + B*phi = C. \ The derived class provides a function to to fill A and B and C. These functions are only meant to be called by DomainNodeBC.

Constructor & Destructor Documentation

FaceNodeBC::FaceNodeBC (    )  [inline]
 

{\bf constructors, destructor and defines}

Default constructor, sets interval to (-1:-1).

FaceNodeBC::FaceNodeBC (  int    a_dir,
Side::LoHiSide    a_sd
) 
 

This constructor sets interval to be (0:0).

Side::LoHiSide    a_sd,
const Interval &    a_comps
) 
 

virtual FaceNodeBC::~FaceNodeBC (    )  [inline, virtual]
 

Destructor.
