[CP2K:6557] Checking for a True Minima

[Olivia Lynes]

Hi Flo,

Thanks for the clarification, I started with optimisations to get used to 
CP2K input/output and timings for larger systems. I'm moving MD when I add 
in the ions, I have a second question if you don't mind- If I'm adding in a 
+2 ion is it just a case of adding the CORE_CORRECTION tag into my KIND 
section for that atom?


Thank you!

Olivia
