I think the answer is "no", although I might have missed one. It would not be
hard to implement this, however: if you have parameters that you like, and
which contain H--O (and presumably, H--H) LJ interactions, you could modify
existing 3-point models to include these terms. Be sure to use new atom
types, since HW and OW have special properties suitable for common water
models.
...good luck....dac
(Real experts might be able to re-use the HW and OW atom types, but there are
subtleties involved that make this dangerous unless you have a good
understanding of how Amber handles conventional water models.)
