Re: Boundary condition
If I understood your problem correctly you want to model a kind of an atmospheric flow. A good way to model the top of such a problem is the symmetry bc if fluxes through the top are negligible. Otherwise you have to use a pressure boundary (with the correct hydrostatic pressure if you are interested in stratification. If I remember it right, Fluent does calculate a pressure stratification only by setting p_ref=0. Otherwise it is not possible to postprocess the phyd_static)
