Hi!

I'm trying to do a classical Von Karman gate, with Re = 10000 and K-epsilon RNG turbilent model. I manage to initialize vortex shedding, but I find that the turbulence disapeares again during the first shedding periode.

I'm using: 15000 elements time stem: 0.01 sec standart wall funcion 1st order unsteady solver

Any surgestions?

Kristine
