Normalized electric fields

GROMACS version: 2020
GROMACS modification: Yes/No

Dear All,
I have a question regarding the use of static electric field in gromacs. Is it normalized, meaning does the potential change with fluctuations in box size or will it remain constant throughout the whole simulation ?


I assume you are referring to the application of an external electric field using the “electric-field-x” options. That applies a force due to the field, specified as potential over distance, to the atoms. There is no actual potential.
