[lammps-users] How to output atom force exerted by other particles

LAMMPS LAMMPS Mailing List Mirror

Dear lammps users,

  Hi.
  For my simulation systems, there is langevin thermo stat. The total force on each atom consists of net force by other particles, and forces coming from langevin equation. The Lammps "DUMP" command can output each atom total force by " fx,fy,fz". But I only want net fore by other particles, not including forces coming from thermostat.

  Thanks all in advance.

Best wishes,

The fix store/force command will store forces before
other constraints (like the Langevin forces are added).
They can then be output by accessing what that
fix stores.
