Software for modelling natural convection

Hello everyone,

I wonder if you can suggest suitable CFD software for modelling natural convection inside a building. The problem is actually quite simple, I just need to calculate approximately the air exchange rate between a lower and an upper domain when the flow is caused by a temperature/density difference. It is ok for the domains to be 2D and rectangular. The software has to be free and easy to learn.

Thanks for your time.

fluent is ok!

Thank you weiz, but I don't have a budget for buying commercial software to solve this single problem, so therefore I am wondering if anyone can recommend suitable free open-source software instead.
