Hi,
Having a non-uniform dielectric permittivity is a non-trivial problem to solve.
I would like to have a solver for such electrostatics in Gromacs,
but it is a lot of work to implement (and to make it efficient).
Reaction field does not do anything for you in this respect.

Subject: [gmx-users] implicit solvent
Hi all,
I am doing some coarse-grained simulations, where I have
removed the solvent molecules from the system. In order to incorporate the
effect of solvent in my simulations, I need to tune the dielectric constant of
the medium.
Will just changing “epsilon_r” in the mdp file work ?
Later on, I want to use two different dielectric constants,
i.e. a near field value and a far field value.
Is there an easy way of doing this or do I need to modify
the source code ?
I don’t understand the reaction field concept well,
still will something on that line work ?
Thanks, Nazish
