The Open Force Field Initiative is a network of academic and industry researchers working together to advance science and infrastructure required for building the next generation of small molecule and biomolecular force fields. Software and data are released under open licensing agreements to enable rapid application, validation, extension and any kind of modification by our users and contributors. This is a place for questions and public discussions about (open) force fields, underlying science and infrastructure, datasets used in force field parameterization and validation, and anything and everything else related to these topics!
