I have already gone through it and got no vortex shedding using the exact methodology that they have suggested. :mad:

Even the vortex shedding i obtained for a cylinder was accomplished using PISO...

For a case where vortex shedding occurs, the solution should not converge and the value of Cd and Cl should oscillate. I tried this for a cylinder and that is what happened.

Also, most sources...

Vortex shedding in sphere

I'm trying to simulate vortex shedding in a sphere at Re 600, but without success. I am using PISO pressure velocity coupling.

Also, i tried providing an initial perturbation to the flow by...
