aerodynamic simulation motorcycle

[LoSte]

hello to all, I must start a thesis in which I make aerodynamic checks on air ducts for cooling a race bike, and then on the whole bike.
I have not yet started and I wanted a advice from you on what program to use(I was recommended fluent, but also comsol) and where I could find qlc tutorial, maybe in Italian of the recommended program.
thanks to all

on the specific problem: between fluent and comsol for that specific problem I choose fluent. If you have starcd or cfx at university, it's fine.

I thank you for the answer and I immediately ask you another problem having already made your own decision. . .
how amount a geometry from pro-e in gambit for meshare and then simulate on fluent?
I have already tried to save the file in iges but it still gives me error.
If you could give me an iute, maybe detailed would be better.
thanks again for the reliability
