[lammps-users] Nanoindentation

Dear All,

I am trying to simulating the nanoindentation of a graphene sheet. The entire simulation is occuring properly. The only problem I am facing is that, during the unloading process even when I reached the initial position of zero from where I have started indentation, the stress is showing a large negative value instead of zero, as some atoms remain stucked with the indenter up to that position.

Please can anybody address the probable reason of this problem?
