[Pw_forum] Mixing factor

[Tommy]

Dear all, even if the topic have already been discussed, however I'd like to ask you if someone can give me a way to define correctly which mixing factor I have to apply for different cases, for instance insulators, semiconductors and metallic systems. 
Moreover, just for my personal curiosity, shall I ask you which kind of general parameters would you set for a scf calculation of a simple cubic zirconia, ZrO2, with the aim of obtaining the DOS? 
Thank you all,
