some more points to consider :

1. 2d simulation may get you different values than 3d URANS or LES simulations. But not too offset you should expect...

2. Very low yplus may get you in trouble. try to put yplus between 1 and 0.1 every where.

Hi!
I've almost solved all my problems and I'm getting the right valued of drag coefficient!
I have a last question: how to increase the number of points of messh on the cylinder's surface?! (in STAR-CCM+)
