.SH DESCRIPTION

.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 

atomic, meso, or continuum scale.
