[gmx-users] mdp file for system without charges

[Mikhail Stukan]

Dear gmx-users,

Could you give me an advice.
I have a system of uncharged LJ particles. How should the electrostatic part of the mdp file look like for the best performance. Is it possible to tell GROMACS that it should forget about electrostatics at all? Or it understands this by itself and thus the performance is independent on corresponding parameters set in mdp file?
(I am planning to use GROMACS 5.0.4)

Thank you very much in advance.

Mikhail
