Creation of a cylindrical particle system

I’m new using LAMMPS. Is possible create a system containing a cylindrical particle surrounded of some kind of atoms? If possible, how I can do that?

what kind of potential and parameters do you want to use for that?

axel.

I think LJ potential.

I think LJ potential.

then perhaps the tri/lj style in combination with lj/cut could work for you:

alternately, you might want to experiment with fix wall/region for the
cylinder shape
