Hi all,
I am trying implement polarizable model for halides
suggested by Roux group.
I am not able to equilibrate such system.
In present gromacs versions this runs on 1 processor (core) only.
System: Sodium Iodide in water
I am using following topology file for iodide.
Anybody has any clue what might be happening?
Question 2: I am having trouble finding implementation details for
thole_polarization.
How would that appear in topology file?
;

Your help will be greatly appreciated
Thanks
