[gmx-users] applied electirc field with use potential

[Christian Blau]

Hi Amin,


It's me again :)

Yes, applying an electric field mixes well with any other potentials you apply.

When you use an additional electric field by using the .mdp options, there is already an additional force added to all 
the forces on the atoms that makes the system respond to an electric field. You would not have to modify any other 
potential to include an external electric field.


Best,

Christian
