I assume you need Stillinger-Weber including three body potentials
between varying, spatially close triplets? That is not something we plan
to implement. You would need triplet lists for that, or loop over pairs
of pairs. Because of the highly optimized nature of GROMACS this would
be a lot of work to implement.
