First,I want to use your laws and then write my code and compare the results. For using your codes, I don't know which classes are suitable for me, and when I create a plane, it seems that the spheres are not attached together, isn't it? A plane is a continuum media, how can I have it? and the constraints on it's edge? I will read "CohesiveFrictionalPM" that Luc scholtes proposal, what do you feel about it? Nasibeh Moradi
