Dear Jan,
Thank you for your response,  this is my reply and new questions,

> In order to reduce the volume of the representative unit and want to
use periodic boundaries

Yes, I first prepare the sample by isostatic compression in all
directions and then apply a water pressure difference between the upper
and lower interfaces in a certain direction, use PFV to solve it to
simulate the erosion process, and then perform a triaxial test. In order
to be able to perform quantitative analysis, it is necessary to use a
representative unit, but the representative unit with a non-periodic
boundary requires too many particles, so after the erosion, I want to
use the periodic boundary to reduce the number of particles in the
representative unit.

>One option is to create a new periodic sample, preserving characteristics of the original sample. Not straightforward either..
The specific process is to save the position and size information of the particles, then read the information of the particles, and generate these particles one by one? Is it possible to directly generate the periodic boundary and then delete the wall?
