Dear users and developlers,

I’m trying to describe the interaction of a system with 3 atoms types using three body potentials, but I got confused how to specify the parameters:

for example, if I want to use “cosine/squared” form to describe the 1-2-3 interaction which has atom type 2 in the center:

1

/

2

3

should I try something similar to :

angle_style cosine/squared

angle_coeff 1 2 3 75.0 100.0

? Thanks a lot!
