The compilation issue of LAMMPS after modifying the pair_sw.cpp file; the relaxation issue of the graphene force field.

[许旭辉]

Dear Developer,

Thank you very much for your contribution. I would like to ask the following questions:

1. For graphene systems, do I still need to modify the pair_sw.cpp file and recompile LAMMPS?
2. I replaced the pair_sw.cpp file you provided in both lammps-2Jun2022 and lammps-29Aug2024, but I encountered the issue shown in the attached image. How can this be resolved?（without modifying pair_sw.cpp）
3. Why did I not observe lattice reconstruction in the small-angle (1.68 degree)twisted graphene system? Is there something wrong with my input file.

Best regards,

Neil
