Dear PWSCF users,<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I have a question about &#39;mixing_beta&#39;
and &#39;mixing_ndim&#39;.&nbsp; In one &#39;scf&#39; calculations, I found it
converges very slowly.&nbsp; The &#39;estimated scf accuracy&#39;&nbsp; remains
almost a constant in the two subsequent iterations.&nbsp; Do you think
whether it will help if I change &#39;mixing_beta&#39; or &#39;mixing_ndim&#39;, making
them larger or smaller?<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Thank you.<br>
&nbsp;&nbsp;&nbsp;&nbsp; <br>
