[QE-users] relax with tefield

[Masum Alihosseini]

Hi all
I want to apply electric field (tefield) to my structure. I've done the
ralax calculation within the both bellow procedure and the results have
been different:
1- First I did optimization without electric field and then repeat the
relax calculation for optimized structure with applying electric field.
2- I optimized straightly my primary (not optimized) structure with
electric field.
I don't know which one is correct, would you please help me?
best regards
