aqib is on a distinguished road
I am running my simulation for steady case but Cl and Cd graph is fluctuating and does not converge....
So, its mean that my case is unsteady.... then i run the unsteady simulation but after few thousands iterations Cd and Cl graph becomes a straight line....
What does it mean?
I can't understand...
