Hi, is it possible to increase the number of digits in the polar output values of CL, CD, and CM? I think I did this once, but really can't remember how ...
Thanks for your help! |

Thank you very much for your reply. I guess I should have mentioned that I'm asking this because I would to see if I can increase the smoothness of sensitivities, calculated from finite differences.

Hi,
I have to calculate Cl Cd for different type of airfoils to vary the angle of attack (alpha), I do in this way: naca0018 pane oper visc 100000 iter 1000 alfa 0 pacc naca0018.pol aseq -30.0 30.0 2.0 pacc quit The results are different from the results of wind tunnel, maybe cause the large variation of alpha. what do you think? |
