[gmx-users] Dielectric Constant

[Life Sciences Inc]

Hi all

Exactly in Gromacs what and where is Dielectric constant option , If for
example I have to run simulations to study behavior of water around
molecules, and I am using experimental value of SPC/E water model as 71 for
Dielectric constant. But in my input file for gromacs where I will put
Dielectric constant is it epsilon-surface, or epsilon-r or epsisilon-rf, it
is little confusing. Kindly someone elaborate .

Thank you
