 October 4, 2007, 05:10 Re: rotating wheels #6 Greg Guest   Posts: n/a Hi, In the case of rotating wheels, there is no modification of shape so mesh has not to move, the only things witch are modified are the boundaries condition (roughness etc) Right now I have turbulent velocity in...300000 cells...I need to fix it!
