Dear all
I want to simulate a graphyne sheet with lammps. I used reax potential for this calculation, but I got below error:
Incorrect args for pair coefficients (pair_reax.cpp:521).
It should be noted, my potential part of input file is here:
pair_style reax

pair_coeff * * ffield.ci-reax.CH C C
I will grateful for anyone help me

It looks like you are passing the parameters the wrong way, see the docs here: http://lammps.sandia.gov/doc/pair_reax.html
