[Pw_forum] Does PWSCF have a bug when optimizing the structure in electric field

[xqhu@duke.edu]

Dear users,

I just checked the PWSCF codes of 3.2.3. Only setlocal.f90 and v_of_rho.f90 
call add_efield. If you look at the codes carefully, you will see the 
add_efield is called only once! Obviously, when you optimze the structure in 
an electric field, the etot_efield is never updated! I guess something must 
be wrong. Good luck!

Best,
