Problem with buoyant solver
 

Hi all,

I've got some problems using the buoyant solver. I tried all of them, but even the tutorial case (hotroom) is not working properly. I would expect, that one can see a heat flame, but the temperature field remains almost constant. For some reason, there seems to be no kinematic transport of the temperature. However, the velocity field seems to be correct. Does anybody have an idea why this isn't working?

Thanks
Daniela
