Dear Gabriel, Thanks for your reply. I have been playing by the amount of "lambda" for a while, I tried lambda=1, 10, 20, 100 but non of those jobs even converged, the energy mostly is oscillating. I did not try "nosym" flag yet, hope that one will help. any other suggestion? any specific thing about initial magnetization which may help in gaining the convergence?
