[lammps-users] bead-rod polymer chain in LAMMPS

Dear all
I want to simulate a bead-rod polymer chain in LAMMPS. I need to fixed the bond distance and not to include bond energy in my simulation.
Can you suggest what bond_style should I use ?
I would appreciate you reply.

Thank you.

You can possibly use fix shake or fix rigid. In which
case it does not matter what bond potential you use -
the bond potential isn’t calculated.
