sami34 is on a distinguished road
I treat the phenomenon of natural convection double diffusion for a mixture of air-h2o and air-co2 in a square cavity
for a number of Ra = 10 ^ 5 then L (length caractristique) = 0.3 m
the problem is:
the convergence in Fluent !
the programe rest calculated ...
then I think the problem is caused by the mesh
I tried several meshes but same result
pleas help me

alors Je pense que le problème est dû à le maillage
J'ai essayé plusieurs maillages mais toujour meme résultat
s.v.p aidez moi

-mAx- will become famous soon enough
if you tried with several mesh and you still have same convergence issues, then I would say it is not a mesh problem.
What gives you an check mesh?
I would try a simple convection problem on your mesh to see if your mesh is guilty
