Need Periodic Boundary Condition for DEM

[cloneorcopy]

Dear Yihao-Shi:
Thank you for your work! Do you have any plan to implement the Periodic Boundary Condition in DEM model? There are several open soure code i found that can achieve this goal. One is provide by Yade which is written with C++ . Another is written by taichi as the same of this project, but it's quite simple with some of limmits that just changes the particle's positon in boundary.
Hope your reply.

We expect to implement the periodic boundary condition in the next version, which may take approximately two months. In addition, could you kindly share with us the use cases where you utilize periodic boundary condition, like modeling granular flows or simple shear test etc.....

Thank you for your reply! Unfortunately I didn't have detail cases to test periodic boundary condition. What I want to use that is to reproduce Guo's Multiscale work. They have some example in Yade' source code, but this is more focused on multi-scale computing.
