What is the syntax to use two different potentials in a single simulation? {MEAM & Tersoff}

01 January 1970 0 1K Report

I am doing a diffusion between Fe and Diamond (C)

Fe-Fe (interaction)–> MEAM potential Fe-C (Interaction)–> MEAM potential C-C (interaction) → Tersoff potential

The potential files are as follows C.tersoff library.meam FeC.meam

I think pair_style hybrid can be used here. Note I want to avoid lammps from taking C-C interaction as MEAM when I use meam potential file and want to avoid Fe-C or Fe-Fe interaction when I use tersoff file.

I read the documentation and have used the understatement to exclude aout atomic pairs but cant get the syntax right. a) pair_coeff 1 2 none b) neigh_modify exclude type 1 2

Document link https://docs.lammps.org/pair_hybrid.html

Can anyone show me the syntax for this?
