Could you please suggest the software, where I can load my 3D model and see how it behave on various conditions (speed - preferably including supersonic, temperature, pressure)?
Both free & commercial variants are interesting.

$\begingroup$ I think this is too far off topic from physics; it really falls under the realm of aerospace engineering. But since it concerns software, you could perhaps try asking on Super User (since I don't think there is another SE site that focuses on engineering). $\endgroup$ – David Z♦ Feb 13 '11 at 4:16

1$\begingroup$ Well, it would not be answered on SU, and as long as Computational Science is stuck on Area, I think we should give it a chance. $\endgroup$ – user68 Feb 13 '11 at 8:43

$\begingroup$ @David: While I agree that this sounds like an engineers tool, I'll offer a possible use case for physics. I don't know if the CFD people use Monte Carlo the way nuclear and particle physicists do, but if they did one of the tools they'd want is a whole experiment simulator for judging feasibility, and this is roughly what it would look like. $\endgroup$ – dmckee♦ Feb 13 '11 at 15:45

If you want something that looks working and don't care much about the details, the standard solution is Fluent.
The nearest Open Source option is OpenFoam.
