Re: Cell mass


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.

Cheers. Chiara
