good morning, I found a github feature request discussion from 2018 where peastman and jchodera discuss incorporating GROMOS into OpenMM. Did that ever happen? What would be the easiest way to use GROMOS(96) with OpenMM? - thanks, dan

No, it hasn't been added, and based on that discussion it sounds like it uses a functional form that isn't supported by OpenMM.
