special_bond

hi

I want to simulate two circular chains in spherical confinement.they have lj interaction.(repulsive).
Is necessary to use of special bonds?
if yes,how to choose the coefficients?
there is,just,excluded volume interaction between beads of chains.
thanks

What makes the particles a chain? Did you define
a bond or angle style? If so, then you probably
want to use special_bonds. It has nothing
to do with the “geometry” of your system, E.g.
whether the chains are circular or not. It has
to do with whether 2 particles that are bonded
to each other should interact only thru a bond style
or also thru a non-bond (e.g. LJ) interaction.
