pi-pi interaction implemention in lammps

Dear all,

I want to simulate polymer system that have pi-pi interaction between chains and reinforcements. I know there is no implemention of pi-pi interaction in lammps.
So, Is there another method to consider pi-pi interaction in lammps? or I can’t simulate these system by lammps.

Regards,

Hamed

I don't know what a pi-pi interaction is.
You'll have to give more details.
