LAMMPS project is a Molecular Dynamics Simulator. LAMMPS project is a Molecular Dynamics Simulator.LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grain systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the mesoscale or continuum levels. LAMMPS runs on single-processor machines or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. The code is designed to be easy to modify or extend with new functionality. LAMMPS is distributed as an open source code under the terms of the GPL license.What's New in This Release:· Changed to using NIST values for constants.· A potential problem with alloy interactions has been fixed.· Improved flexibility of user customization of output.· The ability to add new styles of atom has been improved.· A new atom method library, non-orthogonal lattice support, and support for semiconductors have been added.· There are code speedups and bugfixes.
