Minor buoyancy problem in Phoen2007
 
Well, I'm not sure it's a minor or major problem, but gravity is ALWAYS a Cartesian phenomenon on terrestial scales, even if a CFD model is cylindrical/polar. Did I miss something about this in the documentation?

The gravity force vector is projected into local coordinate directions. Therefore, for cylindrical polar coordinates, the vector is projected into the circumferential, radial and axial directions.

OK, then I guess I didn't miss anything. Thanks!
