Question #153042 on Yade changed: https://answers.launchpad.net/yade/+question/153042
Chiara Modenese proposed the following answer: I better clarify what I said. If, after having reached your goal porosity, you unload your sample, then obviously you also change porosity itself. I am not sure how much though. Maybe someone else can comment on this? Am curios myself. Cheers.
