2d Fluent and Airfoil

[SkyEng]

Hi everyone,

I need to make some visous calculations on Fluent (Cl, Cd, Cm, Cp) for an NACA 0012 type airfoil and I would like to know which geometry coul be the most apropriate for your opinion between, C, O and H and moreover which type of structure (unstructured, algebric, hyperbolic or elliptic).

if you have done such type of simulation before and if you have some tips to get better results modifying the settings please let me know...

Thanks
