Thank you for your answer! But if electric field was screened by the outside water in the box ,how I decide the size of electric field in the protein when I used "E_x = 1.0 0.71e-2 0" and solute wall distance of 1 nm?
Best wishes!

Dear gmx users:
     I would like to apply electric field to my simulation box, and I have added these to my input file:
; Format is number of terms (int) and for all terms an amplitude (real) =
; and a phase angle (real) =
E_x             = 1.0 0.71e-2 0
What I want to know is whether the size of this electric field in my protein inside the box will be screened by the water around the protein?

Yes. Water had high epsilon(0)

Best wishes!
