LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is a classical molecular dynamics code. LAMMPS can model an ensemble of particles in a liquid, solid, or gaseous state. It can model atomic, polymeric, biological, metallic, or granular systems using a variety of force fields and boundary conditions.

If you use LAMMPS results in your published work, please cite:

Installed on blacklight.


  1. Create a job script which includes commands to
    1. Set up the module command.
    2. Load the module command. You can see which modules are available by typing
      module avail lammps
      and then load the appropriate one with
      module load lammps
    3. Use mpirun to run the executable.
  2. Submit the job script with the qsub command.
