All lammps user，
I am new to lammps, I have write a lamps code about the CBN grinding wheel to cutting Fe alloy,there are 4 atoms in my program. I have used the hybrid eam/fs tersoff lj/cut 10.0 as a pair_style and define the pair_coeffs, while the lammps shows all pair coeffs are not set. I can’t figure out the problem about my code.
the pair define as follow:
pair_style hybrid eam/fs tersoff lj/cut 10.0
pair_coeff * * eam/fs Fe_mm.eam.fs Fe Fe NULL NULL #Fe-Fe
pair_coeff 1 2 lj/cut 0.00759200 3.5 9.7625 #Fe-C
pair_coeff * * tersoff BNC.tersoff NULL NULL B N #B-N
pair_coeff 1 3 lj/cut 0.0071 3.0 #Fe-B
pair_coeff 2 4 lj/cut 0.004068 3.367 #N-C
pair_coeff 2 3 lj/cut 0.003311 3.411 #B-C
pair_coeff 2 2 lj/cut 0.00284 3.4 #C-C
I also see the log.lammps file and find when the lammps program read the command ‘run’,it will stop.
the attachment is my code.
