Question #700369 on Yade changed: https://answers.launchpad.net/yade/+question/700369 Status: Answered => Open 孙灿 is still having a problem: I tried this string of code. The simulated figure is very close to what I want, but the outermost figure I need is smooth, like a circle. The outermost up, down, left and right directions of the graphics simulated by this string of code are not smooth.

Question #700369 on Yade changed: https://answers.launchpad.net/yade/+question/700369 Status: Open => Answered Jan Stránský proposed the following answer: > Sorry, I may not know the terminology very well. > I'm a beginner and don't know much about terms. I also did not know (or remember) the term annulus, but it is not difficult to search the mathematical term, especially if you see that the others do not understand the meaning of vague and ambiguous descriptions. > I think what I'm talking about is annulus. Think? I hoped for more solid result :-) like yes or no Ok, assuming annulus, do you mean something like this? ### r = 1 ro,ri = 30,15 d = 1.5*ro outer = pack.inSphere((0,0,0),ro) inner = pack.inSphere((0,0,0),ri) plane = pack.inAlignedBox((-d,-d,-1.5*r),(d,d,1.5*r)) predicate = (outer - inner) & plane spheres = pack.regularOrtho(predicate,r,gap=0) O.bodies.append(spheres) ### If yes, there are maaany ways how to achieve this, depending on your needs.
