Hi everyone, I am new to cp2k and I have a few questions I would like to get your help. I am using the molecular dynamics module of CP2K and applying periodic electric fields to the system. I want to know how the electric field affects the magnitude of the resulting potential energy? Why is the potential energy obtained by continuing molecular dynamics with the restart file under the same electric field very different from the previous ratio? What energy does potential energy specifically contain? And when I use a large electric field value, I get a warning of electric field anomalies, can my simulation still be used in this case?How can I know the specific electric field change value of molecular dynamics?Below are screenshots of my two input files, potential energy change values and warnings of electric field anomalies.<img alt="potential energy.png" width="421px" height="325px" src="cid:2d0bbc2f-f7b9-4a9b-b92a-14014832a45e" /><img alt="warning.png" width="495px" height="45px" src="cid:a584ccb8-07ab-44de-be3f-ddd7ebf080f3" /> -- You received this message because you are subscribed to the Google Groups "cp2k" group.
