I have to face some problem in my system in the pair style command. I want to run a LAMMPS script for the water droplets on the graphene-coated copper substrate. For that case, I didn’t understand what should I do in pair style command. Already I search for getting solve this problem on the LAMMPS website but I didn’t understand. My potential part of my script is given below:
pair_style hybrid airebo 3.0 4 4 lj/cut/coul/long 10.0 lj/cut 10.0
pair_coeff * * airebo CH.airebo C NULL NULL NULL NULL #C-C
pair_coeff 2 2 lj/cut/coul/long 0.006739 3.166 #O-O
pair_coeff 2*3 3 lj/cut/coul/long 0.0 0.0 #O-H
pair_coeff 4 2 lj/cut 0.004062790 3.19 #C-O
pair_coeff 4 3 lj/cut 0.0 0.0 #C-H
pair_coeff 1 1 eam Cu_u3.eam #Cu-Cu
pair_coeff 4 1 lj/cut 0.02578 3.0825 #C-Cu
where is my atom types are:
group hydrogen type 3
group oxygen type 2
group water type 2 3
group copper type 1
group carbon type 4
after doing that I got this error message:
“Incorrect args for pair coefficients”
Here I also attach my sample script and screenshot of the error message.
Please give me a solution, I didn’t understand to read style command from LAMMPS website.
Thanks in advance.
