An automated framework for generating optimized partial charges for molecules
CHARMM and AMBER forcefields for OpenMM (with small molecule support)
A project (and object) for storing, manipulating, and converting molecular mechanics data.
The Open Forcefield Toolkit provides implementations of the SMIRNOFF format, parameterization engine, and other tools. Documentation available at http://open-forcefield-toolkit.readthedocs.io
Automated tools for the generation of bespoke SMIRNOFF format parameters for individual molecules.
Force fields produced by the Open Force Field Initiative
