Default problem with drag coeficient
Posts: n/a

i am trying to have the flow over a cube with round corners (3D model). i have modelised it and solve it in unsteady flow but when i look at the drag coeficient i have something like Cd converging to 1500???? it should be realy smaller isnt it?? can ssomeone can tell me if it is really the drag coefficient.

thanks for all
