<p>Dear Jayfe,</p>
<p>having a closer look at your input I'm a bit confused about some
things but lets try to stick first to your specific<br>
problem - you mentioned in your first email, that the calculation
is running with elements other than Mn and<br>
that you thus think that Mn is the problem.</p>
<p>Now, did you try replacing the pseudopotential?</p>
<p>Looking at the graph of the SSSP:
<a class="moz-txt-link-freetext" href="https://www.materialscloud.org/discover/sssp/plot/precision/Mn">https://www.materialscloud.org/discover/sssp/plot/precision/Mn</a><br>
I see that the pseudopotential you're using might have some
problem - even with a dual of 16 it is not really<br>
looking good until a cutoff of about 120 Ry. Sure, phonons and
related properties are different from standard<br>
scf convergence, but it is weird. Maybe try using the older 0.3.1
version of the pslibrary.</p>
<p>Did you try to increase the cutoff?</p>
<p>Considering the very same graph of the SSSP, I think that a
cutoff of 45 Ry is just not enough for Mn.<br>
Try increasing in reasonable steps (i.e., 50, 60, 70) with a dual
of 8 or 16 for the 0.3.1 or the 1.0.0 version of<br>
the pslibrary, respectively. If it converges (only one scf, no
relaxation, but printing the forces) compare results<br>
to see what might be a converged value. How big is the change in
the total energy? How do the forces<br>
converge? What about magnetization? And so on and so forth... The
standard way to get a reasonable set of<br>
ecutwfc and ecutrho for your system...</p>
<p>So, concerning your input:</p>
<p>I know that you created the input with some tool, but it does not
make sense. You should check this...<br>
First of all, delete everything which you don't use, just to be
sure that there is no problem. Why do you set<br>
esm parameters, if you don't use the method? Why is eamp still set
to a finite value? Before trying some<br>
different diagonalization methods try the standard 'david'.
startingpot and startingwfc usually don't need to<br>
be set.</p>
<p>In summary, I would try to change the pseudo and increase the
cutoff. And I would clean the input. Then you<br>
need to make convergence checks.</p>
<p>Regards</p>
<p>Thomas</p>

giving your inputs on my case last week. I do hope you can

<p class="MsoNormal">I would like to give you an update on my
predicament on optimization process. Attached in this email is
my input file in which the eamp was set to zero. During
calculations, the results are still oscillating for each
iteration. I didn’t stopped the calculation but I can see that
it’s not going better. It even gave a positive value for
calculated scf energy per iteration as seen in this pic:</p>
