Reply To: Savonius 2D simulation, Cp increasing after stall point

The left image is pressure contour for tsr=0.6 (corr. to top velocity contour) and right is for tsr=1.1 (corr. to bottom velocity contour which you mentioned)

I am calculating the torque/moment sir in my case for finding the Cp. 

But I see sir, so my domain is my problem. You are saying that it is causing the back pressure and interferring with the current iterations. Hence, I need to take a bigger domain?
