I've already tried to use OpenFOAM, but I couldn't figure out how to
simulate
a flow whose turbulence is caused by an object whose movement is
caused
by the flow. All the examples I've found were with fixed parameters.
I'm afraid
I can't use OpenFOAM for this kind of problem.
Is there any other possibility? I'm using linux, it hasn't to run
under widows.
