Dear gmx users:
I would like to apply electric field to my simulation box. I have
already read the manual and I added this into mpd file as manual told:
; Electric fields = 7.1e-10V/nm
; Format is number of terms (int) and for all terms an amplitude (real) =
; and a phase angle (real) =
E_x = 1.0 7.1e-10 0
;E_xt =
;E_y =
;E_yt =
;E_z =
;E_zt =
as I know, this line E_x = 1.0 7.1e-10 0 would add x direction
7.1e-10V/nm electric field, but in the MD simulation log file the three number
is
efield-x:
n = 1
a = 0.000000e+00
phi = 7.100000e-10
efield-xt:
n = 0
efield-y:
n = 0
efield-yt:
n = 0
efield-z:
n = 0
efield-zt:
n = 0
why phi = 7.100000e-10 and a=0? Are a and phi the strength of the electric
field and phase of the cosine?
