Hi Dear LAMMPS users
I have written a data file that describes an aqueous solvent of NACL as you see in the attached file. But when I ues read_data in LAMMPS, this message appears that:
Unknown identifier in data file: 6578 0 4 1 34.667 13.502 9.531
what is wrong in this data file?
Thanks a lot for your advice
