[gmx-users] How to define a user-defined potential

[Divya Rai]

 I wanted to know how is it possible to model a user-defined potential and
run MD simulation through Gromacs? The tabulated potential has a specific
form as defined in the manuals. What if my potential lacks it? Taking an
example of Muller-Brown, how can I use Muller Brown potential for my MD
simulations through Gromacs?
Kindly help.
