Tersoff potential

Dear LAMMPS Users,

I am new to using LAMMPS. I have a problem regarding the use of Tersoff potential to model a crack in silicon sample.
I am always getting “ERROR: Incorrect args for pair coefficients (pair_tersoff.cpp:273)” when I execute it.

Can you please help me?

Thank you,
Fatima

not really. this error means, that your input is incorrect
where you set the "pair_coeff" command.
please read in the documentation what is the correct way
to use it and also about how to debug it.
