Hi,
I'm studying the problem of a turbulent flow over a circular cylinder and I'm trying to display the vortices in the wake of the bluff body.

Unfortunately I'm not getting the expected achievements, since I obtain only a kind of steady wake but not the typical alternating vortices.

Where can be the problem?

I've setted the "implicit unsteady" as time physical model, I'v chosen a reasonable (I hope ) time step using the relationship about the frequency of vortex shedding in a circular cylinder [0.05s (D=0.1m,V=5m/s)] and an arbitrary number of inner iterations (25).

Thanks!
bye
