<div dir="ltr">Dear All,<div class="gmail_quote"><div dir="ltr"><div><br></div><div>I am trying to perform
non-magnetic calculations for SmBi treating Sm 4f electrons in the core
region. I have followed the example given for Yb by Prof. Blaha. The
steps that I have performed are as follows. <br></div><div><br></div><div>I
performed a normal non-magnetic scf calculation using run_lapw and from there found
out where the Sm 4f states are from the case. scf file. In case.inc file,
I added two lines 4, 3, 5 and 4, -4, 0, (to keep Sm 4f 5/2 and Sm 4f 7/2
states in the core and since Sm in +3 configuration has 5 electrons, so
I have kept the occupations no as 5 for Sm 4f 5/2 and 0 for Sm 4f 7/2)
increased the number of orbitals from 14 to 16 and added a downward
shift of 0.6 Ry. In case.in1, I changed the value for Sm 4f states from
<br></div><div><br></div><div>3 0.30 0.0010 CONT 1 <br></div><div>to <br></div><div>3 -1.00 0.0010 CONT 1, <br></div><div>so that the Sm 4f states will not be found by lapw1. <br></div><div>After that in case.in2 I removed 5 electrons and reduced the number NE</div><div>TOT (TOT,FOR,QTL,EFG,FERMI)<br> -12.0 31.0 0.50 0.05 1 EMIN, NE, ESEPERMIN, ESEPER0, iqtlsave</div><div><br></div><div>from 31 to 26 as follows:</div><div><br></div><div>OT (TOT,FOR,QTL,EFG,FERMI)<br> -12.0 26.0 0.50 0.05 1 EMIN, NE, ESEPERMIN, ESEPER0, iqtlsave</div><div> </div><div>After this I ran dstart first and then did a normal scf run. For the first 39 cycles there was no problem but then an error came in the 40th scf cycle as follows:</div><div><br></div>LAPW2 - FERMI; weights written<br>L2main - QTL-B Error<br>L2main - QTL-B Error<br><div><br></div><div>cat *.error<br> 'l2main' - QTL-B.GT.15., Ghostbands, check scf files<br> 'l2main' - QTL-B.GT.15., Ghostbands, check scf files</div><div><br></div><div>lse</div><div>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_29.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_2.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_30.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_31.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_32.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_33.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_34.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_35.error<br>4 -rw-r--r-- 1 root root 54 Oct 19 00:58 uplapw2_36.error</div><div><br></div>:FER : F E R M I - ENERGY(TETRAH.M.)= 0.0628473771<br></div><div>I followed previous threads and then tried everything as suggested by Prof. Blaha in the link as follows:</div><div><a href="http://susi.theochem.tuwien.ac.at/reg_user/faq/qtlb.html">http://susi.theochem.tuwien.ac.at/reg_user/faq/qtlb.html</a>.
