[gmx-users] Restraints of COM

[Eudes Fileti]

Hello everybody, I have two benzene molecules and I
want to restrain them only by their center of mass. The
conversation below (between Shirts and Spoel) gave me
some ideas but still I couldnt solve the problem. In particular
I'm not seeing any way to create this user group, nor how to
calculate its center of mass. Could someone give me a
hand with that?
