<div dir="ltr"><div><div><div>Dear QE users <br><br></div>I am doing relax calculation for copper ferrite. In the ouput file from starting its giving convergence has been achieved in 176 iterations. but at the end, it shows <br>End of self-consistent calculation convergence NOT achieved after 500 iterations: stopping. I didn't get any final enthalpy and coordinates but at the end, it is showing that Job is done. <br></div>What does that mean ? Whether the relax calculation is completed or not? What can be the issue that at the end it has not converged?<br>I am attaching the input please have a look. <br><br> &CONTROL<br> calculation = 'relax' ,<br> restart_mode = 'from_scratch' ,<br>
