Large-scale Atomic/Molecular Massively Parallel Simulator

Introduction to LAMMPS

Developed by Sandia National Laboratories, LAMMPS is an open-source software package designed for molecular dynamics simulations. It implements multi-machine parallel computing using MPI and provides empirical potential functions for atoms in the periodic table. LAMMPS is adept at simulating real systems, such as metals or water, with results consistent with experimental data. Learn more about LAMMPS, also here its LAMMPS GitHub.

Key Features of LAMMPS

  • Versatile Simulations: Capable of simulating liquid, solid, and gaseous states, and a variety of system types including all-atom, polymer, biological, metallic, granular, and coarse-grained models.
  • Optimization Algorithms: Employs well-established algorithms for efficient simulation of particles in different states.
  • Diverse Model Potentials: Offers a range of model potential functions for systems like polymer chains.
  • Multi-Scale Simulation Capability: Suitable for atomic, mesoscopic, and continuous scale matter systems.
  • Advanced Material Modeling: LAMMPS is a classical molecular dynamics code with a focus on material modeling.
