If I do the supercell of 3*3*1 everything is ok, I can get the beautiful results. However, when I do the supercell of 3*3*3 or 2*2*3, the ghost bands will showed up and the calculation will stop in lapw2. So I just wonder why in this particular supercell, the problem happened.</li><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo2'>When I initialized the system, the setrmt I enter the reduction in 0% . So the RMT for Nd Sr Ni O is 2.5 2.43 1.98 1.70. And the nn set I just use the default 2. Everything else I use the default, the Ecut is -6 Ry. And the I do the spin polarized calculation and plus the orbital U into the system.</li><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo2'>I don’t quite understand what is the HDLO in case.in1. I think the problem maybe is the Nd has two energy found too close to each other. However, in the other good calculation, the case.in1 is same for Nd, only the Ef is different, the Ef is much smaller than other case, the Ef in 3*3*1 is 0.656 Ry. Is this the problem? How can I fix the problem? </li></ol><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Looking forward to your reply!</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>--------------------------case.in1------------------------------------------------------------</p><p class=MsoNormal>WFFIL EF=.3000 (WFFIL, WFPRI, ENFIL, SUPWF)</p><p class=MsoNormal> 7.00 10 4 ELPA pxq BL 64 (R-MT*K-MAX,MAX L IN WF,V-NMT,LIB)</p><p class=MsoNormal> 0.30 6 0 (GLOBAL E-PARAMETER WITH n OTHER CHOICES, global APW/LAPW)</p><p class=MsoNormal> 0 0.30 0.0000 CONT 1</p><p class=MsoNormal> 0 -2.96 0.0001 STOP 1</p><p class=MsoNormal> 1 0.30 0.0000 CONT 1</p><p class=MsoNormal> 1 -1.48 0.0010 CONT 1</p><p class=MsoNormal> 3 0.30 0.0010 CONT 1</p><p class=MsoNormal> 2 0.30 0.0010 CONT 1</p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:gsabo@crimson.ua.edu">Gavin Abo</a><br><b>Sent: </b>Saturday, February 29, 2020 10:25 PM<br><b>To: </b><a href="mailto:wien@zeus.theochem.tuwien.ac.at">wien@zeus.theochem.tuwien.ac.at</a><br><b>Subject: </b>Re: [Wien] Ghost bands problem</p></div><p class=MsoNormal><o:p> </o:p></p><p>To add to that:</p><p>a) Sometimes, but not always, such errors can be resolved by updating to the latest WIEN2k version and starting from a fresh directory (with only the case.struct in it). You didn't mention, are you using the latest WIEN2k 19.1? If not, as the WIEN2k 19.1 updates page states, Version 19.1 is a major update. Are you also using any or all of the WIEN2k 19.1 patches from the mailing list? A list that I have assembled is at [1].</p><p>b) General tips for resolving a ghostbands error like the one you have below should be in section "12.1 Ghost bands" of the WIEN2k usersguide (starting on page 246) [2].</p><p>c) I could be wrong, but I thought recalled calculations on structures with Nd possibly being more challenging. You might have a look in the mailing list archive for past posts on Nd, such as [3] and [4].</p><p>d) For some other tips that might help with the "semicore band-ranges too large, ghostband" error, refer to [5].</p><p class=MsoNormal>[1] <a href="https://github.com/gsabo/WIEN2k-Patches/tree/master/19.1">https://github.com/gsabo/WIEN2k-Patches/tree/master/19.1</a><br>[2] <a href="http://susi.theochem.tuwien.ac.at/reg_user/textbooks/usersguide.pdf">http://susi.theochem.tuwien.ac.at/reg_user/textbooks/usersguide.pdf</a><br>[3] <a href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg18345.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg18345.html</a><br>[4] <a href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg18367.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg18367.html</a><br>[5] <a href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg10561.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg10561.html</a><o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>On 2/29/2020 6:44 AM, Laurence Marks wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal style='margin-bottom:12.0pt'>Without more information nobody can help you.<o:p></o:p></p><div><p class=MsoNormal>_____<br>Professor Laurence Marks<br>"Research is to see what everybody else has seen, and to think what nobody else has thought", Albert Szent-Gyorgi<br><a href="http://www.numis.northwestern.edu">www.numis.northwestern.edu</a><o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Sat, Feb 29, 2020, 06:14 <span lang=ZH-CN style='font-family:"Microsoft YaHei",sans-serif'>姜若诗</span><span lang=ZH-CN> </span><<a href="mailto:ruoshijiang@sjtu.edu.cn">ruoshijiang@sjtu.edu.cn</a>> wrote:<o:p></o:p></p></div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Dear experts,</p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I got stuck on the problem when I do the supercell calculation of heavy elements Nd. </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>The normal cell calculation is everything good, but it supercell calculation, the ghost band showed up in lapw2.</p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>-------------------------------error message---------------------------</p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>'LAPW2' - semicore band-ranges too large, ghostbands ?</p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>-----------------------------------------------------------------------------</p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Do you know how to fix it ?</p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Looking forward to your reply.
