[CP2K-user] [CP2K:19935] help: Full_kinetic not available for semi-empirical methods

[Alex Lyu]

Hi JH,

Thank you, I have just noticed your reply. Since then I have started PM6 
semi empirical method but the SCF is not converging... not sure what I can 
change?
I have tried changing the minimiser, preconditioner, extrapolation, 
scf_guess etc but nothing is working right now.
