it is where it should be: printed in the output. If it is not there,
you did not specify the data (i.e. gaussian smearing) that allow to
calculate a sensible Fermi energy. In that case, the code prints
the top of the valence band (or the HOMO) and the bottom of the
conduction band (or the LUMO). If it doesn't, you haven't specified
the number of bands to be calculated and the code calculates
occupied bands only
