Dominik Boemer posted a new comment: Hello Bruno, suppose that I have a ball mill with rotation axis z of radius r and length l (in z direction). In this case, I will use O.cell.refSize=(2*r, 2*r, l) to create the periodic boundary condition. Thus, the mill seems to have an infinite length (along z). As you pointed out, this is absolutely correct (for any rotation point (a,b,c), i.e. the rotation of the liner is defined by a direction and a point). But, as Jan explained, the post-processing gets a little inconvenient if the rotation point is (0,0,0). In this case, I see a rectangular parallelepiped with one quadrant of the mill in each of its corners. Until now everything is fine. But these quadrants are turned to the outside, such that the liner (projection) almost looks like an astroide (hypocycloid with four cusps). I want, however, to see the liner like a circle and this is why I had to translate the mill and its content from (0,0,0) to (r, r, 0); it's just a matter of post-processing.
