In some flow situations like viscous flow over a cylinder, the outlet BC in FVM is taken as a zero-normal-gradient condition i.e.,
d(rho)/dn = 0 d(vel)/dn = 0 dp/dn = 0 First of all is this correct ? Secondly how do you implement this in practice in a 3d unstructured grid finite volume formulation ? I would be interested to know if there are differences for cell-centered and node-centered schemes. |
