Dear Gromacs users,

                I am planing to have a reference atom(non-bonded) in my
system, whose position will not change during simulations and  shouldn't
feel/exert  any force from/on the other atoms(ghost atom).
How can I do this in  gromacs ? can I set  electrostatic and  van der waals
parameters to zero ?
or is there any efficient way to do this ?

Any help will be highly appreciated.
