Hi,

I'm trying to model (2DH) a cylinder (3m diameter) inside a tank (width 50m and length 250m) with a free stream of 2.5m/s.
I dont have any problem modelling and running the simulation, but once I see the results I can't see the Von Kármán eddies. I think it is something related with boundary conditions.
The pilar has a wall boundary condition type, with no slip. Something that surprise me is that the walls of the tank and the pilar aren't separate, all appear as wall. When I did the mesh I separate walls and pilar...

The mesh discretization is fine to ensure solve the scale of the eddies, each element in the wake is 1/12 of the pilar diameter.

Does anyone knows what I can do?

Thanks in advance,

Eduardo
