Dear LAMMPS’s user,
I am confused over the figures calculated by LAMMPS. I set the area of cylinder so that it creates ~13572 atoms but LAMMPS created 13170 atoms. What is wrong with codes? Here is my script and LAMMPS’s output:
script: -
atom_style granular

Please can anybody explain about the area created by LAMMPS (bold in above) as I put the area of cylinder and but it looks as an area of box!!? And why it creates wrong number of particles?
Thanks…
Ram
