[lammps-users] [Help] Any suggestion on choosing the proper EAM?


There is two types of EAM universal potential files which is provided by LAMMPS, one is u3 and another is u6. I wander what is the difference between them? I want to simulate a low dimensional system (i.e. films or wires), is there any suggestions on which type is more accurate for such systems?


I would read the papers the potentials were described in.
