<table cellspacing='0' cellpadding='0' border='0' ><tr><td valign='top' style='font: inherit;'>Dear all<br><br>While doing Density of states calculation for a semiconductor with an impurity i am facing the following problem. I am calculating for a supercell of 128 atoms. The scf calculations are done and then the DOS calculations starts and below is the lower portion of the *.dos.out file. <br><br> <br>The potential is recalculated from file sic.rho<br> Starting wfc are atomic<br><br> total cpu time spent up to now is 32932.47 secs<br><br> Band Structure Calculation<br> Davidson diagonalization with overlap<br> WARNING: 47 eigenvalues not converged<br> WARNING: 11 eigenvalues not
converged<br> WARNING: 7 eigenvalues not converged<br> WARNING: 6 eigenvalues not converged<br> WARNING: 3 eigenvalues not converged<br> WARNING: 3 eigenvalues not converged<br> WARNING: 47 eigenvalues not converged<br> WARNING: 12 eigenvalues not converged<br> WARNING: 4 eigenvalues not converged<br> WARNING: 2 eigenvalues not converged<br> WARNING: 2 eigenvalues not converged<br> WARNING: 47 eigenvalues not converged<br> WARNING:
8 eigenvalues not converged<br> WARNING: 2 eigenvalues not converged<br> WARNING: 1 eigenvalues not converged<br><br>This warning messages continues for around 4 /5 days and then either it stops the calculation or it writes all the expected oputput files but the DOS curve obtained is wrong.<br> can anybody please advise no this.<br>regards<br>Padmaja<br><br><br><br></td></tr></table><br>
