<div dir="ltr"><div>Hello Everyone,</div><div><b>This has been almost 3 months since I'm stuck at one error only! </b>With
12 atoms (one unit cell) of FeS2, the bands calculation runs good, but
with 96 atoms, it shows the following error <b>EVERYTIME</b>: (1st scf, then
bands calculation)<br></div><div>bands output:<br><br></div><div>....</div><div>Band Structure Calculation<br> Davidson diagonalization with overlap<br> c_bands: 5 eigenvalues not converged<br> c_bands: 4 eigenvalues not converged<br> c_bands: 1 eigenvalues not converged<br> c_bands: 4 eigenvalues not converged</div><div> ........<br></div><div>After
this, the program doesn't calculate the band structure even if it shows
JOB DONE. The faulty band structure is attached herewith. I have also
given all the inputs and output files.</div><div><br></div><div>KINDLY PLEASE help me or enlighten me to solve this error. I will be greatly indebted to you. Thank you.<br></div><div><br><div dir="ltr"><div dir="ltr"><b style="color:rgb(34,34,34)">Regards,</b><div style="color:rgb(34,34,34)">Dipta Mahanta</div></div></div></div></div>
