Hallo,

I want to calculate a free convention flow in a closed domain. So I choose buoyantSimpleFoam! After testing the tutorial I tried a small case. In the results I see that the plume is going to the left wall and not to the upper one. First I look to the gravity definition but all is OK. I tried some other things like changing BC ... but every time the same problem. So I rotate the domain and the plume is going to the top wall! So that: g = (0 9.81 0)T.
Is there somebody how know this problem and can give some advices to fix the source code?
Have somebody experiences with heat driven flows in OpenFOAM and can give me some advices in cosing the right turbulence model and the associated BC!

Thanks

Preibie
