[CP2K-user] [CP2K:12212] Re: Spin Polaization in Kohn-Sham calculations

[Ronald Cohen]

Oh I understand. Of course that need not be integer. So the printed multiplicity when relax multiplicity is on is incorrect. What about the number of electrons? It prints a renormalization when Multiplicity =3 and also shows the same number of up anddien when multiplicity =1 even with relax multiplicity on. I can send that output if you like. Thank you!
