Starting with a reasonable guess of the ground state can make convergence faster. Please notice that starting_magnetization is assigned by atomic type, not by atom. > Whether will it influence the final magnetism of a system? Normally not (except for the trivial spin up/spin down inversion) but in some pathological case two distinct non-degenerate solutions could exist and be separated enough that the initial guess can matter. > > Thank you! > Best regards! you're welcome -- Dr. Lorenzo Paulatto IdR @ IMPMC -- CNRS & Universit?
