I can't think of a non deterministic CFD program, although I don't have much experience at all. Certainly in my CFD course at Uni, non deterministic programs were never mentioned.
I should have said above that even if you did have the computing power for every particle in the flow, that you would have very different initial conditions for every flow field anyway. How do you define where all the molecules are in the real flow? There would be an infinite spread of possibilities, so making the problem insoluble anyway.
CFD is a hard business, despite spending ages on a fairly simple problem, I got some amazingly strange results from a CFD program (rubbish in, rubbish out!). It takes a lot of knowledge and skill to get it right and even then the results can be misleading.
