<div><p>Dear all,<br>I am trying to calculate Born effective charges from DFTP for the spin-polarized system. However, these systems must be treated as metallic (scf-calculation with occupations='smearing').<br>The problem is that ph.x complains about my calculation, but the system has an insulator behavior.<br>
Are there any methods to solve this problem?<br> <br>Sincerely,<br>Sergey Nikolaev<br>Department of theoretical physics and applied mathematics<br>Ural Federal University<br>Yekaterinburg, Russia<br><br></p></div>
