I was trying to find an approximate value of delta_n, i.e. overlap distance between the particles, so I thought about looking at the dump files I am getting and see how the value given for the diameter of each particle had changed with respect to the initial assigned diamter (i.e. radius in the input script).
But I have seen that most of the values over are more than the initial one, some are less, and some are of negative sign.
1- so may you please inform me what is the reason for that
2 -Is this the right way for getting the delta_n?
3- Is there another way for that?
