LAMMPS
The LAMMPS software simulates classical molecular dynamics, with a focus on materials modeling.
About LAMMPS
LAMMPS is a classical molecular dynamics code with a focus on materials modeling. Its name stands for Large-scale Atomic/Molecular Massively Parallel Simulator. The homepage describes it as software that is downloaded and run, either on a single processor or in parallel, rather than as a hosted web application. It includes potentials for solid-state materials such as metals and semiconductors, and for soft matter such as biomolecules and polymers. It can also model coarse-grained or mesoscopic systems, and the homepage notes it can be used as a parallel particle simulator at the atomic, meso, or continuum scale.
The homepage states that LAMMPS is distributed as open source software under the GPLv2 and that all development takes place on GitHub. Pricing is not stated on the homepage.
