In the CFX Manual they say that the discretisation of the advection term is as follows :
phi(ip)=phi(up)+beta*dphi*dr and they say that phi(up) is the value at the upwind node. I don't really understand what's the upwind node. Cause if the integration points are located at the center of each surface segment surrounding the finite volume, then the nodes are all at equal distance of the integration point. |
