Method to keep a group of neighboring atoms as neighbors throughout the NVT simulation

Dear all

I would like to know if there is a way to keep a group of atoms in the simulation as neighbors with a specified neighbor cut-off such that the atoms are free to move within the cut-off. Neighbor cut-off is the minimum distance between two adjacent atoms in the group. I want to know if its possible to do this in a direct lammps simulation.



Thanks for the quick reply.
