Steve,
In regards to the script line below:
pair_coeff 12 12 Al_jnp.eam
I wanted to check if this line implies that all interactions between atom types 1 and 2 will be mediated by the potential in Al_jnp.eam.
Also, in regards to the line:
pair_coeff 1*2 3 Al_jnp.eam
Does this line mean that all interactions between atom types 1 and 3, as well as interactons between atom types 2 and 3 will be mediated by the potential in Al_jnp.eam?
Thanks,
Sreekant
