description

LAMMPS is a classical molecular dynamics code that models an ensemble of particles in a liquid, solid, orgaseous state. It can model atomic, polymeric, biological, metallic, granular, and coarse-grained systems using avariety of force fields and boundary conditions. http://lammps.sandia.gov
