bene New Member Join Date: Apr 2010 Posts: 10 Rep Power: 16	Hi all, I'm modeling a rotating disk and I would like to make a symmetric grid to save time for the calculations. I tried to draw only a quarter of the disk, projecting it over two simmetry axes; I noticed that there are problems with the rotation because when I expand my quarter to see all the disk the directions of the rotation in each quarter are opposite. How can I do to garantee the continuity of the disk rotation in the symmetric case? Is it possible to use the symmetry in this case? Thank you Bene
