What cycle is that for?  As described at [1], case.dmatup/dn must be present for orb to run.  If it is happening in the first scf cycle, it might be fine since I believe case.dmatup/dn are created during cycle 1 such that you won't see orb until cycle 2.

Dear Wien2k users,

                            I have started a simulation with GGA+U approach. However, during SCF, I have noticed, orb -up/orb - dn is not coming...the case.dayfile is given below as;

Am I doing something wrong??
