Indentation Stress-strain response

Dear LAMMPS users,

I am trying to determine the stress-strain relation of a nanoparticle similar to the paper (http://aip.scitation.org/doi/pdf/10.1063/1.3552985)

  1. To create a boundary for the nanoparticle to move along the force, do we need to have any real substrate or can we restrict the movement of nanoparticle using boundary keyword.

I don’t know what this means. If you mean the boundary command in LAMMPS,

then the simulation box boundaries do not “restrict” particle motion at all. See

the boundary doc page for details.
