Hi Bruno, since as you say it is a mass density, that would not work. I mean, I have tried different cell dimensions (I guess that is what you mean with size of the period) and have employed different size distributions. In all the cases, the same problem was shown. This mass value influences very much the stability, and one has only to guess about it (I mean, it is a random number, depending also on the micromechanical parameters chosen). Besides this, it does not have a proper physical meaning for the purpose of the simulation. That is why I do not understand its role. I think we could write the algorithm in a simpler way, if you have any ideas how to do it differently do let me know.
