[Wien] Eorb =0 in LDA+U case.outputfiles

I don't see any lines in your BiFeReO6.outputorb[up/dn] like:

Atom 9   L=  2 U=  0.300 J=  0.000 Ry
Atom 10 L=  2 U=  0.300 J=  0.000 Ry

So there might still be a problem with your BiFeReO6.inorb file.

Did you adjust BiFeReO6.inorb and do the scf calculation again?

If you only want to apply U values to atoms 9 and 10, then remove atoms 
11 and 12 from the inorb and indm files.
