[lammps-users] chunk/atom

Dear LAMMPS users,

I need to divide the simulation box to the small cells and get the density of each cell and then I need to subtract the density of each cell to the average density of all of them!

As I know, the “compute 1 all chunk/atom bin/3d” can help me in this case!
but the thing is, I do not know how to get each cell’s density!

Can you please let me know how I can get each cell’s density?

Thanks for your attention and help in advance.
