I am new to the Ansys Fluent. I want to a calculate 3d object drag coefficient but it doesn't consistent with real values so i susptect my mesh. I share my y+ values. Is it correct ?
p.s. I use spalart - allmaras models, compressible flow (ideal gas with viscosity model is sutherland), v0 = 2.8 mach, inlet boundary conditions far field pressure and outlet conditions pressure outlet. (Sorry my English.)

Though SA model is less sensitive to near wall mesh quality, still, you need to use a mesh much finer than that you have. should be of order 1, i.e., below 10 to give good accuracy.
