Dear professor:
i have some troubles about the lammps, and i want to get your help.
i wang to use tersoff to describe the interaction of C-C,eam/fs for the Al-Al,LJ for C-Al, just like the following,
pair_style hybrid lj/cut 12.0 tersoff eam/fs
pair_coeff * * tersoff 1 C.tersoff C NULL
pair_coeff * * eam/fs 2 Al_mm.eam.fs NULL Al
pair_coeff 1 2 lj/cut 0.0309 3.422
but the log shows:
#-----力场-----
pair_style hybrid lj/cut 12.0 tersoff eam/fs
pair_coeff * * tersoff 1 C.tersoff C NULL
ERROR: Incorrect args for pair coefficients (…/pair_tersoff.cpp:299)
Last command: pair_coeff * * tersoff 1 C.tersoff C NULL
so what should i do to correct it？
Looking forward to your reply.
