<div dir="ltr"><div dir="ltr">Dear Lorenzo and Paolo,<br><br>Yes, I recompiled the code correctly this time and it seemed to have worked. Thanks for all the inputs.On an ending note, I wanted to know if you had any thoughts on the magnitude of exchange and correlation parts. Here's a value that I obtained: <div>Exchange contribution: -161.43363281 Ry<br></div><div>Correlation contribution: -11.572000000 Ry<br><br>What is immediately noticeable is the much smaller magnitude of correlation part. I wonder if there is a universal physical reason behind this (I'm using PBE functional) or maybe it's just an unremarkable feature of my system. </div><div><br>Thanks for all the help. <br></div><div><br></div><div><span style="color:rgb(80,0,80)">Sincerely,</span><br style="color:rgb(80,0,80)"><span style="color:rgb(80,0,80)">Shivesh Sivakumar</span><br style="color:rgb(80,0,80)"><span style="color:rgb(80,0,80)">University of Washington-Seattle</span><br style="color:rgb(80,0,80)"><span style="color:rgb(80,0,80)">WA-98105</span><div class="gmail-yj6qo gmail-ajU" style="outline:none;padding:10px 0px;width:22px;margin:2px 0px 0px;color:rgb(80,0,80)"><br class="gmail-Apple-interchange-newline"></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jan 23, 2021 at 1:09 AM Lorenzo Paulatto <<a href="mailto:paulatz@gmail.com">paulatz@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>Did you recompile le code after changing it?</div><br><div><u></u>--<br><span style="font-size:0.9em;color:gray">Lorenzo Paulatto - Paris<span></span></span><u></u></div><div>On Jan 23 2021, at 7:27 am, Shivesh Sivakumar <<a href="mailto:shiveshsivakumar@gmail.com" target="_blank">shiveshsivakumar@gmail.com</a>> wrote:</div><blockquote><div><div>Dear Lorenzo,</div><br><div>Thank you very much for the hint.
