[lammps-users] Question relating to pair_style, pair_coeff

Steve, LAMMPS users,
I wanted to confirm if the lines of script below is doing what I am intending. I have the simulations running, and upon visualization of the atoms, I am not sure if what I am seeing is incorrect.

I have 4 atoms types: 1 and 2 are aluminum, while 3 and 4 are silicon. I would like the interactions between atom types 3 and 4 be via Stillinger-Weber, between atom types 1 and 2 via the EAM potential, and the interactions 13, 23, 14, 24 via the lj/cut potential.

Looks correct to me.
