But scf calculation for graphene can't achieve convergence. I've tried different mixing_beta, mixing_mode, degaus ant ecutwfc. The example input file is attached. Could you please tell me which parameters I should tune to achieve convergence?</DIV><DIV><BR></DIV><DIV>Thanks in advance,</DIV><DIV>Koroteev Victor</DIV><DIV>PhD student,</DIV><DIV>Nikolaev Institute of Inorganic Chemistry SB RAS<BR>Novosibirsk, Russian Federation. </DIV><DIV id="M2Signature"><DIV><BR></DIV></DIV></BODY></HTML>
