Set aside a few weeks, look in share/top/oplsaa.ff, copy it to oplsua.ff in your working directory, rework the contents according to the OPLS-UA literature and your knowledge of chapter 5 of the GROMACS manual and test the results against a suitable reference implementation of OPLS-UA. Good luck! Mark
