-.B LAMMPS 
-LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale 
-Atomic/Molecular Massively Parallel Simulator. LAMMPS has potentials for soft 
-materials (biomolecules, polymers) and solid-state materials (metals, 
-semiconductors) and coarse-grained or mesoscopic systems. It can be used to 
-model atoms or, more generically, as a parallel particle simulator at the
