<div dir="ltr">Dear Wien2k users,<div> I want to simulate antiferromagnetism in FeO. For that I have created a struct file (attached in the mail) in which the nearest neighbour Fe are presented as inequivalent atoms. I have edited the case.inst file and flip the spin of
nearest neighbour Fe atoms. I have also added U = 5eV for all the Fe (4 in numbers) atoms. During volume optimization I got the following error </div><div><br></div><div> cycle 1 (Tue Jun 23 19:44:11 IST 2020) (40/99 to go)<br><br>> lapw0 (19:44:11) 12.4u 0.1s 0:06.79 185.7% 0+0k 0+6072io 0pf+0w<br>> lapw1 -up -orb (19:44:18) 42.8u 20.6s 0:24.38 260.2% 0+0k 0+41480io 0pf+0w<br>> lapw1 -dn -orb (19:44:42) 44.7u 19.3s 0:19.66 326.1% 0+0k 0+41440io 0pf+0w<br>> lapw2 -up -orb (19:45:02) 0.0u 0.0s 0:00.02 300.0% 0+0k 0+8io 0pf+0w<br>error: command /usr/local/Wien2k/lapw2 uplapw2.def failed<br><br>> stop error<br><div><br></div><div>The case.output2up & case.scf2up are empty.</div><div><br></div><div>Thanks in advance.</div><div><br></div><div>with regards, </div>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div style="font-size:small">Dr. Shamik Chakrabarti</div><div style="font-size:small">Research Fellow </div><div style="font-size:small">Department of Physics</div><div style="font-size:small">Indian Institute of Technology Patna</div><div style="font-size:small">Bihta-801103</div><div style="font-size:small">Patna</div><div style="font-size:small">Bihar, India</div></div></div></div></div></div></div></div></div></div>
