A set of spheres with known radius, how to pour those spheres to a box


Here has a set of spheres, the radius are known. Spheres’ information are listed in a file:

ITEM: ATOMS type id radius

1 1 2.385

1 2 1.324

So how can I pour such spheres to a defined box in LAMMPS? Thanks!

The fix pour command has a diam option which can

be used for pouring polydisperse particles.
