comb3 and hybrid/overlay

Dear all users

I am trying to run a simulation with 3 atom types (H (1), C (2), Cu (3)). I want to use lj/cut for interaction of Cu with H and C and for the other interactions I want to use comb3 potential by following hybrid or hybrid/ovelay pair_style:

Dear all users

I am trying to run a simulation with 3 atom types (H (1), C (2), Cu (3)). I
want to use lj/cut for interaction of Cu with H and C and for the other
interactions I want to use comb3 potential by following hybrid or
hybrid/ovelay pair_style:

you cannot partition a manybody potential like that since it is not
pairwise additive and with the setup below you *add* lj/cut
interactions to COMB3.

------------
pair_style hybrid/overlay lj/cut 7.0 comb3 polar_off
pair_coeff * * ffield.comb3 H C Cu
pair_coeff 1 3 lj/cut 0.02248 2.135
pair_coeff 2 3 lj/cut 0.415 2.277
------------

LAMMPS throws the following error when I try to run a script containing
these commands:

ERROR: Pair coeff for hybrid has invalid style
(../pair_hybrid_overlay.cpp:68)

Am I missing something here? because based on what I read in Manual (May
2015) it seems to be correct

not is is not. the first pair_coeff line is wrong. it doesn't contain
a label indicating which sub-style it belongs to. hence it reads
ffield.comb3 as style which doesn't exist and therefore you get the
error.
