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 file. )
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 expectation. 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 :) YK Lee -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
