[Pw_forum] Finite electric field on ZrS mono-layer

[Sohail Ahmad]

Dear PWSCF usersI am using QE 5.0.1 and 
wish to apply finite homogeneous electric field on ZrS2 monolayer but i am getting error as 
  Berry Phase/electric fields only for insulators!
Input file is attached ,,,,, please comment - what change is required .
