<div dir="ltr">Dear Prof. Blaha & all,<br><div><br></div><div> I may have solved the problem by following the FAQ on the wien2k website. I have reduced the mixing parameter to 0.05 & have changed the scheme to PRATT. It has already run for 3 cycles without showing any error. As advised in FAQ I will change the scheme to MSEC1 after a few iterations to reach the final convergence.</div><div><br></div><div>with regards,</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, 20 Mar 2021 at 23:29, shamik chakrabarti <<a href="mailto:shamik15041981@gmail.com">shamik15041981@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear Prof. Blaha,<div><br></div><div> I was trying to simulate the voltage for the reaction LiCrTiO4 to Li2CrTiO4.

<p>I checked the files you sent in the large emails.</p>
<p>This is NOT a B3LYB calculation (I was curious anyway because of
the large cell)<br>
</p>
<p>The scf1up file shows;</p>
<p>LDA+U potential added for atom type 9 L= 2 spin up<br>
and all other TM atoms.</p>
<p>So what are you really doing ??</p>
<p>Did you run a normal GGA calculation first ??<br>

<div>I am running a simulation on a compound (str file
