The drag coefficient is negative at high angle of attacks!!
however at 0 angle of attack it seems to be OK. the lift coefficient is acceptable and good at all AOA. What is the problem. I would say its my inputs when in the boundary conditions for pressure farfield; i have it as X component= cos (10) and Y component = sin (10) please help me |
