<div dir="ltr">Hi,<div><br></div><div>I tried to run your calculation with the only difference that:</div><div>i) qe version il 7.2 instead of 7.3</div><div>ii) pseudopotentials are La.pbe-spfn-kjpaw_psl.1.0.0.UPF Mn.pbe-spn-kjpaw_psl.0.3.1.UPF O.pbe-n-kjpaw_psl.1.0.0.UPF</div><div><br></div><div>The calculation is running and completed the first scf cycle giving as output total force 0.004199, pressure -220.25, total energy -6961.50519193,</div><div>total magnetization 35.01.</div><div>Now, I would exclude that changing the version of qe would transform a converging calculation into a non converging one. There could be some issue in your pseudo,</div><div>but this is unlikely too, because I did not use pseudos from a completely different library. So, I'm not sure about what makes difference between my and your calculation.</div><div><br></div><div>By the way, during the calculation I also got suspicious messages saying that </div><div>Minimization algorithm failed to find Fermi energy: reverting to bisection<br> Possible cause: smearing is larger than the electronic band-gap.<br></div><div>and which however did not prevent the calculation from converging.</div><div><br></div><div>Just to check, i rerun the same run, changing only smearing to 'mv'. This also gave a converged calculation with total force 0.001821, but in 24</div><div>iterations (within the 1st scf cycle) instead of the 45 of the previous run.</div><div><br></div><div>So, although I couldn't exactly explain why my calculation is converging and yours is not, I would suggest changing the smearing.</div><div>Also consider that within the UPF file for La I downloaded, the suggested ecutwfc is 74 Ry, due the fact that La orbital require more plane waves to</div><div>be accurately described. So I would certainly make some convergence tests to see possible differences between 60 Ry (yours) and 74 Ry (suggested).</div><div><br></div><div>Giovanni</div><div><br></div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><span style="color:rgb(0,0,0)">-- <br><br>Giovanni Cantele, PhD<br>CNR-SPIN<br>c/o Dipartimento di Fisica<br>Universita' di Napoli "Federico II"<br>Complesso Universitario M.
