[gmx-users] electrostatic interaction

[nishap.patel at utoronto.ca]

Hello,

    I want to turn off electrostatic interactions between CH4 and SOL  
in my system. I am using ffG53a6 forcefield for CH4 and spc for my  
water model. CH4 is an united atom and so I can't make the charges  
zero in the topology. Is there any other way I can turn off  
electrostatic interactions?

Thanks.
