New question #706167 on Yade:

Hello, I write simple script, where I create container (walls are used for
this), spheres and apply gravity. The simulation perfectly works at this state.
For some reasons I need periodic cell in my work script and I get issue when
try to do this. Simulation stucks after some iterations number. It stucks even
without spheres, so I guess problem is about walls but I've no concretize
ideas. It would be great if you can tell me what is wrong and help fix this
problem. Thanks.
