How do I impose a uniform initial overlap in a granular DEM simulation in LAMMPS?

22 October 2020 1 1K Report

Hello everyone,

I am trying to replicate the process done in the paper 'Shocks near jamming' by Gomez et al (PRL, 2012) where the granules are initially in a pre-stressed state with initial overlap between granules. What they do is perform a dynamic uniaxial compression while having periodic conditions on the lateral surfaces.

How can I do this in LAMMPS?

Thanks for your input!
