[gmx-users] Distance restraint between two chains' com

Dear Gromacs Users,

I am trying to apply a distance restraint between two chains' center of
mass to  prevent them diffusing far away from each other. As I known, the
pull code seems only can restrain the distance to a reference distance with
 harmonic potential, while the distance restraint seems can not be applied
to center of mass.

So can anyone help on this issue?

Best regards
