Dear PWscf Users<br><br><br>I get the below lines in the first iterations but after the iteration # 4 or 5 disappears and again in the next steps the story repeats.<br><br> Davidson diagonalization with overlap<br>c_bands: 1 eigenvalues not converged<br>
c_bands: 4 eigenvalues not converged<br><br>As proposed in the manual and forum I tried to ran the Job without considering symmetry and the number of such lines reduced but did not disappear completely and <br>the vc-relax calculation in such way is too time consuming and not completed yet. <br>
My system is a 3 layers graphite with palladium impurity. I do not know that I must be worry of encountering such lines or not? Also, May you please say me the "c_band" is related to my Carbon atoms or not? I appreciate your help.<br>
