can Discs be used instead of sphere in LAMMPS

hi all,

can circular Discs be used instead of sphere in LAMMPS for 2d simulation

If you mean you are using atom_style sphere, then
you can use them in a 2d simulation, e.g. a granular

model (see examples/pour.in.pour.2d), but they
are still spherioids so far as their density/mass and

moments of inertia. Other than that there will be
no components of motion/rotation in z, so they are
disc-like.
