Dear users,
I am doing ZnO slab calculation with 12 Double layer of ZnO. Since ZnO is a
wide band-gap material, so I am using occupation=fixed. I attached my input
also.
But why the calculation is not converging?

But when I am using occupation=smearing, it do converge. But it gives a
work function of 3.47 eV after applying the dipole correction.

So what mistake I am doing?

Please help me in this regards
