<!--SOHUMAIL_HTML_HEAD_END-->Dear Wien users & developers,<p>I have recently done some calcuations on AlN doped with Er. LDA+U method<p>is used to treate Er 4f electrons. Here are my operations step by step:<p>1. A directory named AlN is created;<p>2. input-files such as AlN.struct, AlN.inst, AlN.indm and AlN.inorb is created.<p>3. init_lapw (GGA, no add-inversion and spin-polarized are selected in this step);<p>4. [hust@icesword AlN]$ runsp_lapw -orb<p> LAPW0 END<p> LAPW1 END<p> LAPW1 END<p> LAPW2 END<p> LAPW2 END<p> after LAPW2, SCF terminated without LAPWDM and LCORE...etc steps. I do know if my operations<p> is correct. Could you tell me the detail steps on how to us LDA+U method?<p>Thank you for your helpl<p>Regards,<p>Zhang<hr size=1><style type="text/css">
