Incorrect Results for drone analysis

hey there, I am not getting proper residual plot and force and moment and force and moment coefficients for the drone analysis. The Cd and Cl values are coming out diverging in nature. I followed tutorial and also other various combinations of boundary conditions. Simulation failed at times. Please guide me.
