LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is a molecular-dynamics code. The code is designed to be easy to modify or extend with new functionality. LAMMPS can run on a single core but is designed to be highly efficient running on a large number of cores in parallel using message-passing techniques and a spatial decomposition of the simulation domain. It solves systems ranging from single atoms through polymers and proteins to rigid collections of particles. A variety of force fields is supported.
Local support is not available. LAMMPS has documentation and tutorials at its Website. It has a large and active community of users; to search or join the mailing list see the instructions here.

To find the available versions and learn how to load them, run:
module spider lammps
The output of the command shows the available LAMMPS
For detailed information about a particular LAMMPS
module, including how to load the module, run the
module spider command with the module’s full version label. For example:
module spider lammps/2Aug2023
|Module Load Command
|module load gcc/11.4.0 openmpi/4.1.4 lammps/2Aug2023
Users may build their own versions of LAMMPS if they wish to use a different compiler and MPI combination, or to choose individual optional packages. Instructions are available at the LAMMPS Getting Started" page.
Example Slurm script
To run the system version of LAMMPS, a script similar to the following can be used. LAMMPS has many options so only the most basic is shown.
#SBATCH --account my_acct
module load intel lammps
srun lmp_iimpi -in run.in.npt
