[DFTB-Plus-User] Clarification on warnings requested

[Sebastiaan Hermans]

Dear,

Since I last updated DFTB+, I am receiving these warnings:

WARNING!
-> Dipole printed for a charged system : origin dependent quantity
WARNING!
-> Dipole printed for extended system : value printed is not well defined

I am simulating a periodic system containing a copper sheet electrode with a negative charge and a large set of point charges.
Could you help me understand these warnings? Is the last warning to attend me to the self-interaction of the point charges in the periodic system?

Kind regards,
Sebastiaan
