LAMMPS Molecular Dynamics Simulator
AMMPS stands for Large-scale Atomic/Molecular Massively Parallel Simulator.
LAMMPS is a classical molecular dynamics simulation code with a focus on materials modeling. It was designed to run efficiently on parallel computers. It was developed originally at Sandia National Laboratories, a US Department of Energy facility. The majority of funding for LAMMPS has come from the US Department of Energy (DOE). LAMMPS is an open-source code, distributed freely under the terms of the GNU Public License Version 2 (GPLv2).
The LAMMPS website has a variety of information about the code. It includes links to an on-line version of this manual, a mailing list and online forum where users can post questions, and a GitHub site where all LAMMPS development is coordinated.
LAMMPS’ manual is organized in three parts: 1) the User Guide for how to install and use LAMMPS, 2) the Programmer Guide for how to write programs using the LAMMPS library from different programming languages and how to modify and extend LAMMPS, and 3) the Command Reference which includes detailed descriptions of all commands included in the LAMMPS code.
Once you are familiar with LAMMPS, you may want to bookmark this page since it gives quick access the documentation for all LAMMPS commands.
