RE: CCL:energy of Cr

hi,
I also had such problems with transition metal.
The problem was with Sfc=QC
when I checked the population of the orbitals, there were completely wrong (I am currently working with DFT and there was an empty electronic level below the Fermi level.
So I now use Vshift, and =300 for the most difficult convergence.

Have you checked that these results correspond to the same
electronic state?, i.e., are the electrons in the same orbitals?
