<p>Dear WIEN2k users,</p>
<p>I am trying to do an AFM GGA+U simulation on GdMnO3, for this I created a supercell to define the up and down spins and every time I run the simulation with U, it crashes in the first cycle with the message "forrtl: severe (39): error during read, unit 9, file (...)/case.vectorup" and the .dayfile says "LAPWDM crashed".</p>
<p>I tried doing the simulations in serial and parallel mode but both give the same error and without the "-orb" option the simulation runs fine. Also, if I try to do a ferromagnetic simulation in the original structure (i.e., no supercell) with U, the simulation runs fine as well.</p>
<p>I am running WIEN2k_14.2 and have the 2016.3.210 ifort version.</p>

<p>I found that the 14.2 WIEN2k version gave an error in LAPW2DM and that it has a patch (<a href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg12595.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg12595.html</a>) but that was for simulations with spin-orbit, which mine do not have. Does this have anything to do with my error, if not, what can I do to fix this?</p>
<p>Thank you for your help.</p>
<p>Best regards,<br />Rui Costa.</p>
