I don't see how to seperate these two phases on yade. In fact what I want to do is to compact my specimen before launching the calculus so that I get the density I wish to have. But here, yade do both phases simultaniously, and the phase at which q takes negatives values is the phase of compaction which corresponds to the first ietrations.
