I want to get the separation and reattachment points in time-averaged simulation results, and I am a little frustrated now.

I checked the text books and it says du/dy=0 or dp/dx=0. I searched the forums and there is not much information about how to detect them.

I try plotting "mean x-wall shear stress" in "unsteady wall statistics" of the airfoil, and it seems to me that the separation point is where shear stress=0 (from positive to negative), and the reattachment point is where shear stress=0 again (from negative to positive).

Can anyone show me the correct way to detect these points? Thanks in advance!!!
