You may want to look into the MARTINI models for biomolecular systems. The
approach would be the same. There is no need for "explicit support" for what
you're doing; GROMACS is an MD engine, like any other. If supplied a valid
physical model, you can simulate anything. GROMACS even handles planets :)
