dump_polarizability

Predicts the polarizability for the current configuration of atoms during MD using a separate nep4_polarizability model. The response model is read by this keyword and is independent of the potential used to run the MD.

Syntax

dump_polarizability <interval> <nep_file>

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

nep_file is the name of the nep4_polarizability potential file used to predict the polarizability.

Examples

Example 1

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

potential nep.txt
...
dump_polarizability 100 nep_polarizability.txt

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

Caveats

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