separation bubble .....
 

Hi: I use AF3F method to solve laminar NS equations, When simulating the flow around Epper 387 airfoil, Re=10**5,alpha=1 deg.... i can not get the laminar separation bubble far behind the leading edge,i think there is something wrong, What caused this? who can help me? thanks!

Do you get separation?

I would think that you would get separation, just no re-attachment. How well does you cl and cd compare with experiments?
