Amber does not offer any easy way to do this sort of calculation. Generally,
Amber users would be likely to use restraints (setting ntr=1), and let the
water equilibrate around the solute. But we don't have any good way that I
know of to do rigid body dynamics. (I hope someone will chime in if I am
missing something here....)
