Hi,
I am trying to simulate the flow over an airfoil NACA0012 with chord C=20mm and Velocity=7.3m/s, Re=10,000, laminar case. I am not getting correct Cd and Cl at different angle of attack in accordance to the experimental results. In reference values I have used Area=.02m^2, Depth =1m, Length = .02m. Is there a problem when I am trying to scale the grid. I change GRID/SCALE " Grid was made in " to cm. since I made 2 units as chord length in gambit. Thanks PARVEZ |

I think Gambit works with metres unless you change the units in the Default menu. Stick to metres from the start, I'd say
