Dear Lammps users,
I use lammps-28 Jun14 version. In my simulation, there are 6 types of atoms (1-3 are Ge, 4-6 are C). I’ve used below commands to define interaction between atoms:
pair_style hybrid tersoff morse 2
pair_coeff 1* *3 tersoff SiCGe.tersoff Ge NULL NULL NULL
pair_coeff 4* *6 tersoff SiCGe.tersoff NULL NULL NULL C
.
.
.
But I get an error “Incorrect args for …”
Also I’ve used these line commands :
pair_style hybrid tersoff morse 2
pair_coeff * * tersoff 1 SiCGe.tersoff Ge NULL NULL NULL NULL NULL
pair_coeff * * tersoff 2 SiCGe.tersoff NULL Ge NULL NULL NULL NULL
pair_coeff * * tersoff 3 SiCGe.tersoff NULL NULL Ge NULL NULL NULL
.
.
.
and I get the same error.
I would be grateful if anyone can help me.
