What did you play with for mixing weights and kick etc? A mixing weight of 0.25 is pretty high, if not excessively high in this case. :) Did you try, say 0.02, or something like that? Also, kicks are *only* necessary when you have problems with stalls in convergence. If you stall after 50 SCF, y

Hi I Camps, Your cut off energy is massive. I would start at 50 Ry and do a cut-off energy convergence test because I am almost sure you would reach convergence way before 500 Ry. Try that and see how It goes. Cheers, EL-abed El-abed Haidar | Doctor of Philosophy (Science) Condensed Matter Theor
