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
