I am running LAMMPS from Oct 29 2020.
I am wondering if there are restrictions using the hybrid/overlay. I try to use the following (bolded), but ended up getting an error:
ERROR: Illegal pair_style command (src/pair_soft.cpp:150)
Last command: pair_style hybrid/overlay soft 1.12246 bpm/spring lj/cut 1.12246
I am able to get some hybrid/overlays to work (ie zero and lj/cut), but I’m wondering why this one isn’t working. I’ve tried the two-way combos as well (soft + bpm/spring, lj/cut + bpm/spring, lj/cut + soft), and these also fail (if I include the “cutoff distance” for bpm/spring also, that fails). How can I make this work?
