openfoam is on a distinguished road
HI jasak sir

I imported Naca0012 fluent file to Foam
i used simple foam as solver. the problem is that i am not getting correct U and P distribution for the U=50m/s,I think i am wrong somewhere giving boundary conditions and one more thing for the different angle of attack how to specify velocity
it is component only naa ,like in this case Ux=50cos0 and Uy=50sin0 for 0 AOA.
