tranviet proposed the following answer:
If you are working with soil sample, the pre-consolidation pressure
should exist, right? In that case, compression may be a good choice to
generate your sample.

If you don't think so, I can only know three ways:

- After the compression finishes in makecloud, allow the sample to stabilize after removing all external pressures acting on it. Save the positions and radius of all particles only  to a file then load the file to have a new sample. By this, your new sample is the same as the previous one but has no interactions between particles (or hope so).
- Don't use compression method, use gravity itself to pack your sample. You will have to modify the code and YADE is an open source code, so this is great.
- There are many other packing methods available, you can define yourself what you like.

Good luck.
