can I use EAM potential with lj units ?!

dear axel please tell me that I change the dimension of the parameter in eam file and use lj units or it is better that i use metal units?


For style lj, all quantities are unitless. Without loss of generality, LAMMPS sets the fundamental quantities mass, sigma, epsilon, and the Boltzmann constant = 1. The masses, distances, energies you specify are multiples of these fundamental values. The formulas relating the reduced or unitless quantity (with an asterisk) to the same quantity with units is also given. Thus you can use the mass & sigma & epsilon values for a specific material and convert the results from a unitless LJ simulation into physical quantities

I wouldnt use LJ units because they are untiless …I would prefer to use Metal units …
