LAMMPS is a classical molecular dynamics code that models an ensemble of particles in a liquid, solid, or gaseous state. It can model atomic, polymeric, biological, metallic, granular, and coarse−grained systems using a variety of force fields and boundary conditions. LAMMPS can model systems with only a few particles up to millions or billions. LAMMPS is designed to be easy to modify or extend with new capabilities, such as new force fields, atom types, boundary conditions, or diagnostics. LAMMPS is a freely−available open−source code, distributed under the terms of the GNU Public License, which means you can use or modify the code however you wish.
LAMMPS was originally developed under a US Department of Energy CRADA (Cooperative Research and Development Agreement) between two DOE labs and 3 companies. It is distributed by Sandia National Labs.
