Dear Prof. Marks and Wien2k community, Good afternoon ! Just a curiosity about the charge convergence criteria. I am optimizing a supercell and the charge convergence limit I am using is 0.001. The same numerical value for the energy convergence. The energy is finally converged, but the charge is not despite the fact that its change is below the limit in the last 10 iterations.
CarbazoleLDAopt.dayfile::CHARGE convergence: 1 0.001 -.0002028 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0006007 CarbazoleLDAopt.dayfile::CHARGE convergence: 1 0.001 -.0002590 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0007240 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0008640 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0005344 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0005217 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0002525 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0004560 CarbazoleLDAopt.dayfile::CHARGE convergence: 0 0.001 .0004130 If I am not wrong, the convergence is achieved after 3 consecutive iterations with changes below the limit, but in my case this is happening for more than 10 iterations without convergence. Could you please kindly explain what may be happening ? Thank you ! Luis
