| [ABINIT](http://www.abinit.org/) | Abinit is a plane wave pseudopotential code for doing condensed phase electronic structure calculations using DFT. |
| [Amber](http://ambermd.org) | A set of molecular mechanical force fields for the simulation of biomolecules |
| [ASE](https://wiki.fysik.dtu.dk/ase/) | ASE is a python package providing an open source Atomic Simulation Environment in the Python scripting language. |
| [ChronusQ](https://github.com/liresearchgroup/chronusq_public) | ChronusQ is a high-performance computational chemistry software package with a strong emphasis on explicitly time-dependent and post-SCF quantum mechanical methods. |
| [CP2K](http://www.cp2k.org/) | CP2K is a freely available (GPL) program, written in Fortran 95, to perform atomistic and molecular simulations of solid state, liquid, molecular and biological systems. It provides a general framework for different methods such as e.g. density functional theory (DFT) using a mixed Gaussian and plane waves approach (GPW), and classical pair and many-body potentials. |
| [LAMMPS](http://lammps.sandia.gov) | LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator. Has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) 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. |
| [libctl](http://ab-initio.mit.edu/libctl) | libctl is a free Guile-based library implementing flexible control files for scientific simulations. |
