Hi ghorrocks,
In my steady state my Cd and Cl graphs are fluctuating.... that's why i am doing Unsteady Case....
Intermittency=1 means flow is turbulent and for '0' it means flow is laminar........

actually in most of the papers one separation bubble is mentioned, but in my case it show some different behavior. More than one separation bubble?
that is quite interesting for me....
