Hello,All

I would like to know about CHECK_ATOMIC_CHARGES, which is used in XTB.Can't it be turned off?If it's F, does it have to be the wrong answer?Are there any cases where it's F?

Best wishes,  
Evelyn

Hi

yes you can turn the check off:

CP2K_INPUT / FORCE_EVAL / DFT / QS / XTB --> CHECK_ATOMIC_CHARGES False

If you do this, you have to check that the program converged on a physically
meaningful state by inspecting the Mulliken charges.
Often you can switch back to the default once you have converged your system
once and you proceed using restarts.
