Dear Steve, lammps users,
Is it possible to add an extra atom type in the input script after reading the data from a restartfile using read_restart command? All of its other attributes like mass, epsilon, sigma can be defined later on in the script.
After looking into various options, it seems like create_box command let you define no. of atom types in the system. This command also needs a pre-defined region. However, by this time, I have already read the restartfile. So, I am not sure if I should use region command with EDGE option or INF option (if that makes sense).
Any info will be highly appreciated.
