Dear all,<br> Has anyone tried LDA+U calculatios using the MSEC1 mixing scheme?<br>I tried some calculations, but a "QTL-B" error occured after some iterations (about 3).<br>The "BROYD" scheme works fine.
<br><br>The case.inm reads:<br>MSEC1 0.0 YES (BROYD/PRATT, extra charge (+1 for additional e), norm)<br>0.20 mixing FACTOR for BROYD/PRATT scheme<br>1.00 1.00 PW and CLM-scaling factors<br>9999 8 idum, HISTORY
<br><br>The newest wien2k version (WIEN2k_08.1) was used.<br><br>Could anyone please give me some hints to address this issue?<br><br>Best,<br>Hongjun Xiang<br>=============================================================
