Hi everyone.

I know this question was more or less already asked but I didn't find clear answer.
Simulating airflow around an airfoil, I have completely different Cl/Cd if I use normal coefficients (U, P) or mean version (an, PMean) - like 3.4 vs 2.7
I am using kepsilon SST, Steady State. Wich one of these sets should I use to get results closer to real values?

Thank you guys.
