Error message about'Incorrect args for pair coefficients'

Dear Sir/Madam,

I tried to use the software (Atomsk) to establish an atomic model, as shown in Al.lmp. However, when I calculated this model in Lammps, I got the error message ’Incorrect args for pair coefficients’. Whether lammps can’t use the atomic model established by Atomsk? Could you please give me some information about how to solve this problem. Thank you very much.

Yours sincerely,

Zhongxue Feng

This problem is solved by following the documentation about how to correctly issue the pair_coeff command for a given system and a given potential. This is not a question of supporting atomsk, but about writing correct lammps input according to the requirements of lammps.
