Hello,
Could you sent a little more information? I just started working on a similar problem. I do not have results (yet), but maybe we can help each other.

Hello Lyna,
Without more information it is very impossible to help you. Please read the first item in the CFD online forum. (http://www.cfd-online.com/Forums/ope...-get-help.html).

With my simulation I tried to change the outlet boundary conditions and that helped.

Best regards
Wouter
