Oh yes, the packing is not stess-free (for that, you would have to use some sort of geometric algorithm). But as long as you have cohesive material (which is the case for rock, as far as I know ;-) ), you can say that the initial distance of spheres is equilibrium for that bond; that's what I do for concrete and it works well. Someone else besides me and Anton uses cohesive material && how do you deal with this?
