[gmx-users] Calculating dielectric constant using g_dipoles and g_dielectric

Hi All,

Can someone give me some insights regarding the context under which we use
the g_dipoles or g_dielectric (as mentioned below the two possible way of
calculating dielectric constant) to calculate the dielectric constant of
some molecule during simulation.

g_dipoles computes the total dipole plus fluctuations of a simulation
>From this you can compute e.g. the dielectric constant for low-dielectric

g_dielectric calculates frequency dependent dielectric constants from the
autocorrelation function of the total dipole moment.

Thanks and Regards,
Bipin Singh
