Forget kram at the moment.
Check case.joint if this file looks ok. It contains the unbroadened imag
epsilon (eps2).
It should be zero up to the band gap, but increase afterwards.
Check the band ranges in case.scf2
You will see how far it reaches in energy above EF.
PS: Hybrid DFT calculation
ok, I can try with more bands. 50 bands correspond to NB+5, which is probably
not enough (I am not sure how many is ‘many’ for optics). As I understand,
optics with hybrids seems beyond what is feasible even with supercomputers…
But increasing the number of bands may not solve the problem I not
