Dear all, <div><br /></div><div>I am attempting to perform an SCF calculation on LiMnPO4 with a PBE0 (PBE25) hybrid functional. The pure PBE calculation had no issues, but PBE0 fails to converge, with the multiplicity changing significantly every single iteration:<br /><br /> *** WARNING in qs_mo_occupation.F:349 :: Multiplicity changed from 7 to 19 ***<br /><br /> 12 Broy./Diag. 0.30E+00 400.2 15.39807722 -74522.5582161609 1.91E+01<br /><br /> *** WARNING in qs_mo_occupation.F:349 :: Multiplicity changed from 19 to ***<br /> *** 23 ***<br /><br /> 13 Broy./Diag. 0.30E+00 400.8 15.09579879 -74512.6360647438 9.92E+00<br /><br /> *** WARNING in qs_mo_occupation.F:349 :: Multiplicity changed from 23 to ***<br /> *** 31 ***<br /><br /> 14 Broy./Diag. 0.30E+00 401.0 14.09569018 -74510.7116384230 1.92E+00<br /><br /> *** WARNING in qs_mo_occupation.F:349 :: Multiplicity changed from 31 to 7 ***<br /><br /> 15 Broy./Diag. 0.30E+00 401.3 13.62624561 -74618.4766177882 -1.08E+02<br /><br /> *** WARNING in qs_mo_occupation.F:349 :: Multiplicity changed from 7 to 11 ***<br /><br />Anyone know what's happening?<br /><br />Best wishes,</div><div><br /></div><div>Christopher</div>
