[gmx-users] defining a 3 body user defined potential

[Ivan Gladich]

Dear Amit
As far as I know, 3-body interaction potential is not defined in
gromacs. If you want to introduce it in Gromacs, you have to change the
source code. It is not easy but not impossible and it was already done
for TIP4P, see Kumar and Skinner, J. Phys. Chem. B, 112,8311-8318, 2008

I hope this help
Ivan
