What programs effectively approximate fluid flow using Navier Stokes equations?

[OffTheRecord]

Does anyone know of a program that can give a good approximation of fluid flow based on the Navier Stokes equations? I know there are FEA programs out there that do linear flow, like in pipes, but what I'm looking for is general flow, for applications that aren't constrained to a pipe. Does such an animal exist?

Thanks!

Yes. There are several computational fluid dynamics (CFD) FEM programs that do this. One of the is FLUENT. Just google Finite Element Fluid Mechanics or Computational fluid Dynamics. There are also programs out there for turbulent flow.
