[Pw_forum] positive fermi energy

[david grifith]

Dear All

I get positive fermi energy (+7.8 eV) for bulk graphite by Quantum Espresso.
Positive energy is meaningless for me here. Would you please say me that in
whcih way QE selects the zero energy?
As I know the vacuum should be considered as zero energy.  I appreciate you
in advance to solve the problem.
