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


Best regards
