Sounds easy to verify. :-) However, how do you manage the Rhie-Chow interpolation in cases with strong density gradients then, since your body force does not seem to enter the interpolation...

Is it stable in time, or does the problem with alpha come back? Since the velocity is unphysical, I would expect alpha to be too. What about the convergence history?...

It seems to me the problem is at the junction between the rectangular and the inclined part of the domain too, where the mesh is still hexahedral. The velocity peaks are all in hex cells too. Your...
