Hi.

I am a new user to OpenFOAM transitioning from FLUENT. Although I've searched this forum quite extensively I was not able to find a solid answer for the definition of the right boundary conditions when the 3d, steady, compressible flow over say a wing is to be studied using as boundaries a symmetry plane (that's easy to define) and a half spherical farfield with a radius = (some number) x (reference length, say the wing's root).

Suppose that the rhosimplefoam solver is used. I've seen proposals to define the farfield surface as "freestream" or "inletoutet".

Which is the better (or correct one)? Suppose that the flow conditions are similar to that of ONERA M6 wing cfd model.

Thank you in advace for your assistance.
