Self consistency: mixing• Cc BAD CHOICE• Linear mixing• Advanced mixing schemes …It is more flexible to mix the density instead of the potential<strong>PWscf</strong> mix the density by default
Example 8: improving convergency• Run the scf calculation for an elongated supercell of 16 Fe atomsrun-fe16.scf &• During the run check the convergency of the total energygrep –e scf –e ‘total energy’ fe16.scf.out• What do you notice??SUGGESTI<strong>ON</strong>• Try to decrease the mixing parameter: mixing_beta = 0.1
