Hi

Run type energy_force is just a single point calculation which includes also the calculation of the forces by contrast to the run type energy. You can select any PRINT_LEVEL and activate print keys in the FORCE_EVAL section as you wish for specific properties:

https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/PRINT.html
https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/DFT/PRINT.html
https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/PRINT/PROGRAM_RUN_INFO.html

Hope that’s what you are looking for

Hi Matthias,
Thank you for the help. I was wondering if there is a similar condensed output format for the RUN_TYPE ENERGY_FORCE as well?

So instead of printing all the things that is being printed at print_level low. It only prints a condensed output similar to the MD one.
The user case is that I'm working on a cp2k gromacs interface that will run ENERGY_FORCE at each step. I want some output from the cp2k but the low is too much and slient is just slient.

Hi

You may try PRINT_LEVEL silent and request explicitly the MD output using this print key section:
https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/MOTION/MD/PRINT/PROGRAM_RUN_INFO.html
with the SECTION_PARAMETER “on”.

I'm interested in doing some QM/MM calculations. However, the PRINT_LEVEL LOW still prints a lot more that I'm actually interested in. The PRINT_LEVEL Slient is too slient. I think it might be helpful to have a  PRINT_LEVEL MD, where only this part is printed for each step.
