[gmx-users] Re: Velocity Auto-Correlation Function

[Viswanadham Sridhara]

Hi Everyone,


I earlier asked a question, but i dint get an answer, so am re-posting the
question.

I tried to calculate diffusion coefficient( from velocity auto correlation
> function) as a function of electric field on a simple water system (216nm^3
> volume), consisting of around 6500 water molecules.
> The diffusion coefficient seems to increase with electric field, though
> the increase is 10% for 1V/nm compared with no E-field case.
> Am I doing anything wrong, or what is the predicted shape of Diffusion
> coefficient Vs Electric field for SPC water model.
> Thanks,
