Dear LAMMPS users,

Does LAMMPS have a repulsion term V®=B/r^n+Dr in the pairwise styles? B, D, r are three parameters.

Thanks,

What is available is listed in the manual. Please check it out at: https://lammps.sandia.gov/doc/Commands_pair.html
Apart from that, any pairwise additive interaction like the one listed below can be implemented through using tabulation with pair style table.

Dear Axel,

Thank you for the reply. I checked manual and didn’t find pairwise interaction like the one listed below. I want to hybrid overlay this function with Buckingham function.How can I resolve the problem?

Thanks,

Wu Minbo
