<DIV>Dear pwscf developers</DIV>
<DIV>     I want to relax with lelfield ,but in the example31 it said that :"To perform a calculations with an electric field, an estimate of<BR>the optimized wavefunctions is needed to build the electric field<BR>operator." So I want to know whether I should optimize wavefunctions before relax with lelfield or not ?<BR><BR>--<BR></DIV>
<DIV>
<DIV>Best regards</DIV>
