Dear Gromacs users,
I’m testing a simple system that has one sodium ion and one chloide ion to
check external electric field.
( Apply strong field along z axis, so I added the line of E_z = 1 10 0 to .mdp
After a short simulation, I used ‘gmx potential’ to check the field.
But the result graphs of potential.xvg and field.xvg were different from my
Although I applied 10v/nm along z axis, the electrostatic potential and
electric field was not around 10V.
Does ‘gmx potential’ calculate electric field and electrostatic potential
including external force I applied, or just a system’s?
If ‘gmx potential’ does not calculate including external forces, is there any
method to check external field was correctly applied?
Thanks for your time :)
