Default simulation of airfoil at high AOA

What are the empirical ways to improve the convergence efficiency and accuracy of cl and cd when simulating an airfoil at high angle of attack ? I can think of packing more grids onto suction side BL region as one way. Is there anything else that might be helpful? thanks!
