Hi

The dipole is stored in the edr file, which output frequency is controlled by
"nstenergy" option in the mdp parameter file. Set it appropriately during your
run (nstenergy=0.003) but keep in mind that it should be a multiple of the time
step.


nstenergy cannot be set this way; it is an integer indicating the interval (in number of steps) for writing energy values. If the values have been saved every 2 ps, there is no way to retrieve them every 3 fs; if more frequent information is needed, it needs to be saved more frequently.

Hello,

I am calculating the dipole moment auto-correlation function for my system
which have 128 cation and 128 anion.

I am saving the trajectory at each 2 ps and using this trajectory for
further analysis.

Can I save the dipole moment and three vectors at each 3 fs?



Thanks

Nilesh
