Dear Sir,
I am using Coarse-grained method to simulate polyelectrolytes brushes in water. And water is replaced by a dielectric background and a heat bath.
Under LJ units, the pair potential of pair_style lj/cut/coul/long was choose.
Now it’s the problem, I’m confused about the value of dielectric constant considering the water as a media.
According to the manual, dielectric constant = 1 means vacuum. How about in water?
Thanks a lot!
