To run the example, you have to compile LAMMPS with the MANYBODY package, including pair_sw_3b_table.h and pair_sw_3b_table.cpp.

A hybrid pair style is used, where pair forces are calculated as a tabulated interaction (table_CG_CG.txt) and the pair style sw/3b/table is only used to calculate the three-body forces.

Therefore, in the Stillinger-Weber file all parameters refering to two-body interactions are set to zero.

As explained in the documentation of this pair style, the .sw file contains the additional lines refering to the tabulated angular potential:
