Alessandro1589 New Member Alessandro Del Buono Join Date: May 2015 Posts: 12 Rep Power: 10	Hi guys, i did a Urans 2D simulation about Re3900 flow over a circular cylinder; i used a mesh with yplus= 23-28 and i obtain result (in terms of Cd and Cl) near to literature value. Then i proved to use a coarser(-40% number off cells) and a finer(+40% number off cells) mesh, but results are bad! Which could be the reason??? Best Regards
