potential_type= lj or eam
lj is the Lennard-Johns potential eam is the embedded-atom method potential
potential lj potential eam
This command sets the interatomic potentials. Currently, a CAC simulation accepts two
potential_style: Lennard-Johns (lj) and embedded-atom method (eam) potentials. One file for the lj potential and four files for the eam potential, respectively, should be provided as input.
