Hi!

Is there a possibility of damping the turbulent behaviour of a flow for a steady state calulation. I have an airfoil and need the liftcoefficient. After the stalling angle the flow is turbulent, of course. So for the lift coefficient there is an fluctuation of about 100% of the value and no steady solution. So I hope there is a possibility of damping.

If I set the relaxation factors lower it just calculation the fluctiation in a higher "time resolution".

Thanks
Andreas
