[Question #692799]: Run the exact same simulation twice but gain different results

Hi,

When I carry out the triaxial compression simulation, I found that I run the exact same simulation twice but could gain different shear response, i.e., loading the same sample.yade.gz, and using the same script for deviatoric loading, but the stress-strain curve and volumetric response is not exactly same, see one example at [1] if you are interested.

I'd like to say that the results of the two are basicly agree very well, the only different just occurs at very large strains.  I am  strict about this because I wonder if there are anything wrong that I am not aware, or it is just some numerical random issues?

Thanks

Leonard
