Dear all

First, many thanks for your response. I couldn't be more thankful.
Either by starting with high Reynolds number or by using initial noise is working now. However, once I increase the resolution the turbulence decays and disappears completely, and I don't know why? I just wanted to make grid independence and my geometry is very small, 10 cm in axial direction & 1 cm along the radius.

Any idea is greatly appreciable.
Ali
