LAMMPS is a flexible parallel molecular dynamics code.  It has potentials for soft materials (biomolecules, polymers), solid-state materials (metals, semiconductors) as well as coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale.
