Dear Lammps Developers and Users:
I use Lammps (7Jnu13) to simulate 4 Silicon nanoparticles in a box, as rigid bodies. I executed 2ns MD run: 1ns using “fix rigid/nvt” and 1ns “fix rigid/nve”.
While visualizing resulted trajectory using VMD, I observe that particles move for 1ns (for “fix rigid/nvt”) and next 1ns, it remains (almost) stationary, running with “fix rigid/nve” and Langevin thermostat.
Does anyone tell what is the issue with my i/p deck or “fix rigid/nve”?
Please find attached input and data file.
(Please remove “.txt” from file names before running Lammps job esp from data file.)
