<DIV>Dear wien users,</DIV>
<DIV> </DIV>
<DIV>Now I am checking the Gaussian smearing method to calculate Fermi energy. I am trying to decrease the smearing parameter (_eval) gradually. Till _eval equals 0.0005 the program runs smoothly. However, when I set _eval equals 0.0001, lapw2 stops and declares the Fermi error. What's wrong?</DIV>
<DIV> </DIV>
<DIV>By the way, may I use this method when I do LDA+U calculations?</DIV>
<DIV> </DIV>
<DIV>Best,</DIV>
