Hi I'm Simulation the Airfoil NACA 0020 but the lift coefficient is 0 and its shouldn't be 0 Does anybody know about the boundary conditions pls help me

Check the actual value as I doubt it's exactly zero. What lift would you expect at an airspeed of about 0.3m/s? You also need to review the mesh as non conformal interfaces are not needed for this sort of simulation.
