<div dir="ltr"> Dear Pietro<div>Thanks for your answer, we didn't observe an explicit error, only 100 iteration runs, but no convergence; and our structure didn't change at all and convergence did not happen. what we think is that convergence did not happen in our system at all, and that is because of not applying <b><u>''high spin'' for Fe</u></b> to this atomic system.</div><div>as an alternative way, we examine this structure with VASP, and there we did not observe convergence problem and converged after a while, but the resulting structure in comparison of experimental data has been changed incredibly.</div><div>I think what can solve our problem is solving convergence problems by applying high spin for Fe atoms in my structure. But I do not know how to introduce high spin to have successful convergence.</div><div>thanks ahead</div><div>Mahsa</div><div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Mar 5, 2021 at 6:21 PM Pietro Delugas <<a href="mailto:pdelugas@sissa.it">pdelugas@sissa.it</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 lang="EN-US" style="overflow-wrap: break-word;"><div class="gmail-m_-733223110299088709WordSection1"><p class="MsoNormal"><span class="gmail-m_-733223110299088709DefaultFontHxMailStyle"><span style="font-size:12pt">Dear Mahsa <u></u><u></u></span></span></p><p class="MsoNormal"><span class="gmail-m_-733223110299088709DefaultFontHxMailStyle"><span style="font-size:12pt">The error message you posted is the one of the MPI library.
