Betreff: [Wien] Convergence problem in mbj potential calculation<br>
<div><div class="h5"><br>
Dear wien2k users,<br>
<br>
I am trying to simulate DOS of a semiconducting material using mbj potential. It has run for 230 cycles now. Also, from cycle 210 to 230 the charge & energy convergence remain stuck at a single value. what should I do now?...should I change the mixing parameter or should I just wait?<br>
<br>
Any response in this regard will be helpful for us.<br>
<br>
with regards,<br>
<br>
