Dear Steve and LAMMPS users,
I have a problem of hybrid potential when stimulating cutting processes. The cutting tool is diamond-C and the cutting material is silicon. My potential script is listed as follows,
pair_style hybrid/overlay tersoff tersoff lj/cut 2.5
pair_coeff * * tersoff 1 Si.tersoff NULL Si
pair_coeff 2 2 tersoff 2 SiCGe.tersoff C NULL NULL
pair_coeff 1 2 lj/cut 1.0 1.5
The error message is
“Incorrect args for pair coefficients (pair_coefficient.cpp:273)”
What’s wrong with my potential script? Thank you very much!
Best regards,
Hao Zhang
Dear Steve and LAMMPS users,

pair_style hybrid/overlay tersoff tersoff lj/cut 2.5
pair_coeff * * tersoff 1 Si.tersoff NULL Si
pair_coeff 2 2 tersoff 2 SiCGe.tersoff C NULL NULL
you list three atom types here, even though
you have only two atom types.
pair_coeff 1 2 lj/cut 1.0 1.5
The error message is
"Incorrect args for pair coefficients (pair_coefficient.cpp:273)"
there is no file pair_coefficient.cpp in LAMMPS, so this
cannot be the error message.
