Question #403385 on Yade changed:
https://answers.launchpad.net/yade/+question/403385

Bruno Chareyre proposed the following answer:
Actually no, the micro-macro relations can always be put in a way such that they do NOT depend on particle sizes. 
In Yade, at least, it is the case (and it is obviously a good feature as you may found out). If you agree that cylinder size/aspect ratio should not play a role either, then interaction radius if any is the only remaining geometrical parameter, but it is in the end a contact parameter more than a geometrical parameter.

What should bee kept the same in every geometry is porosity,
coordination number, and fabric (an)isotropy. I think that's it.
