Hi Elene,


You have only 1 atom type in the structure and yet you defined two atom types in the pair_coeff command, hence the error.

Dear Lammps Users,


I am trying to run MD for one SWNCT(10,10). I have never used aired potentials before but I followed the manual but I end with the following error Incorrect args for pair coefficients (../pair_airebo.cpp:161). I checked the pair coefficients and every thing looks fine. Here is a copy of the input file.  I did not include all the file because the simulation stop at pair coefficient
