[gmx-users] NaCl

[nishap.patel at utoronto.ca]

Hello,

     I want to simulate a simple NaCl ion in water. I know the method  
using genion which adds individual Na+ and Cl- ion, but I wish to  
simulate Na-Cl connected rather than free ions floating in water. When  
I ran the grompp command I got the error:
No default Bond types
So I am thinking, I need to add b0 and Kb values for NaCl? Is that correct?

I would really appreciate some help!

Thanks.
