> Dear all QE users, <br />> <br />> I am trying to run relax
calculation for my ZnO system. There are <br />> something I want to
ask. <br />> 1. In running relax calculation, what occupations should I
use? I am <br />> trying to use occupations = 'tetrahedra', but it
doesn't work. I am <br />> afraid if I use occupations = 'smearing', my
result calculation doesn't <br />> valid since ZnO is a semiconductor,
not a metal. <br /><br /> For semiconductor
occupations=fixed<br />> <br />> 2. After my relax calculation is
done, should I run a scf calculation <br />> again with atomic
positions I get from relax calculation? <br /> <br
/> For what?<br /> <br />> I also attach my
input file. Thank you very much for your attention. <br />> <br />>
