Has anyone implemented a boundary condition of the following type in OpenFOAM?



Where (from Ferziger and Peric [page 273]):

phi = any dependent variable (e.g. velocity, pressure etc.)

U = A velocity that is independent of location on the outflow surface and is chosen so that overall conservation is maintained (i.e. it is the velocity required to make the outflow mass flux equal to the incoming mass flux).

If nobody has done this, I would like to do it. However I would appreciate some guidelines. I am farily OK with C; C++ is fairly new to me. Any help in this regard is most appreciated. Thanks
