dump_dipole

Predicts the dipole for the current configuration of atoms during MD using a separate nep4_dipole model. The response model is read by this keyword and is independent of the potential used to run the MD.

Syntax

dump_dipole <interval> <nep_file>

interval parameter is the output interval (number of steps) for evaluating and writing the dipole.

nep_file is the name of the nep4_dipole potential file used to predict the dipole.

Examples

Example 1

To use nep.txt to propagate the MD and nep_dipole.txt to compute and write the dipole every 100 steps, write:

potential nep.txt
...
dump_dipole 100 nep_dipole.txt

before the run keyword. This will generate a dipole.out output file containing the time step and predicted dipole at that time step.

Caveats

  • This keyword is not propagating. That means, its effect will not be passed from one run to the next.
