Open-Source Software Tools and Modeling Packages

Ab initio quantum software

• GAMESS: the General Atomic and Molecular Electronic Structure System is a general ab initio quantum chemistry package
• PSI4: an open-source suite of ab initio quantum chemistry programs designed for efficient, high-accuracy simulations of a variety of molecular properties
• NWChem: aims to provide its users with computational chemistry tools that are scalable both in their ability to treat large scientific computational chemistry problems efficiently and in their use of available parallel computing resources from high-performance parallel supercomputers to conventional workstation clusters

Molecular dynamics software

• LAMMPS: a molecular dynamics package especially designed for materials simulations (Sandia National Laboratories)
• GROMACS: a highly parallelized and fast molecular dynamics package with a number of analysis tools included
• OpenMD (GitHub files): an open-source molecular dynamics engine that is capable of efficiently simulating liquids, proteins, nanoparticles, interfaces, and other complex systems using atom types with orientational degrees of freedom (e.g. "sticky" atoms, point dipoles, and other coarse-grained assemblies). Proteins, zeolites, lipids, transition metals (bulk, flat interfaces, and nanoparticles) have all been simulated using force fields included with the code. OpenMD works on parallel computers using the Message Passing Interface (MPI) and comes with a number of analysis and utility programs
• NAMD: a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems
• HOOMD-blue: a general purpose simulation package optimized for GPUs

Monte Carlo software

• Cassandra (GitHub files): an open-source atomistic Monte Carlo package capable of simulating any number of molecules composed of rings, chains, or both. It can be used to simulate small organic molecules, oligomers, and ionic liquids. Cassandra uses OpenMP parallelization
• MCCCS Towhee: a Monte Carlo package that uses configurational bias and other advanced Monte Carlo moves to simulate phase equilibria and other equilibrium properties
• RASPA2 Classical molecular simulation code
• GOMC (GitHub files): an open-source software for simulating molecular systems using the Metropolis Monte Carlo algorithm. The software has been written in object oriented C++, and uses OpenMP and NVIDIA CUDA to allow for execution on multi-core CPU and GPU architectures. GOMC employs widely-used simulation file types (PDB, PSF, CHARMM-style parameter files) . GOMC can be used to study vapor–liquid equilibria, adsorption in porous materials, surfactant self-assembly, and condensed phase structure for complex molecules.
