LAMMPS
Public development project of the LAMMPS MD software package
...It is designed for high-performance computing and can run efficiently on desktops, clusters, and supercomputers. The software is widely used in materials science, chemistry, physics, nanotechnology, soft matter, and computational engineering. It supports many interaction models, including pair potentials, many-body potentials, reactive force fields, bonded interactions, long-range electrostatics, and user-extendable packages. LAMMPS is script-driven, so users can define simulation geometry, force fields, integration methods, output, and analysis behavior through input files. ...
