Default Vortex shedding from a cylinder
Cylinder Case

I am trying to investigate the shedding vortices from a cylinder.

As a start I have looked at the case presented by CHAM. unfortunatley some of the details are missing. With my simulation I do not get the alterante (top, bottom)vortices shedding.

Has anyone got any details of an appropriate test case? or the complete details given by CHAM.

For reference the study I am trying to reproduce is located at

Me too! I've gotten it to work from Library case 808, I think it is, with laminar turbulence model - but as soon as I invoke the Smagorinsky turbulence model (Large Eddy Simulation) the vortex shedding disappears.
