Bruno Chareyre proposed the following answer:
>But I think I can't use the triax engine in my case. Because there
shouldn't be any confining pressure applied on the spheres, the internal
compaction must be disabled.
Hi,
I don't think you have a choice, if you want to control porosity precisely. You
need triax engine (it could be also the periodic one). You can always unload
the packing to confining pressure ~0 before the predicate thing, so that the
contact forces will be null or negligible.
