Can lammps simulate a system by using different potentials ?

hi ,Steve.

To simulate a system with many kinds of atoms , different kinds of atom-pair may need to use different potential type , can lammps do this???

If it can , how I do it?

Thanks.

If I had ten hours to cut woods,I will spend eight sharping my axe and two for cutting.

yes, see the pair_style hybrid command.
