Dear all:<br><br>I try to calculate AFMII-type NiO with mBJ potetial including SO. However mBJ potential seems to conflict with SO.<br><br>1. After spin-polarized calculation, give up antiferromagnetic calculation and do mBJ calculation. Everything is ok. But when I include the SO case.grr not found are reported. Error message like following:<br>
<br>Error in LAPW0<br> &#39;LAPW0&#39; - case.grr file not present, which is requred for mBJ<br><br>What is the problem?<br><br>2. Alternately I did SO first after spin-polarized calculation without antiferromagnetic calculation. Then I calculate with mBJ potential. This time at the step: runsp_lapw -NI -i 1 I got error message like following:<br>
<br>runsp_lapw -NI -i 1<br>hup: Command not found.<br> LAPW0 END<br> LAPW1 END<br> LAPW1 END<br> LAPW2 END<br> LAPW2 END<br> CORE  END<br>
