[lammps-users] Radius of particle

Hello, to all!

There is such a question:

I want to create a set of usual atoms (gas) and another particles with
a large Radius (100 x Radius of gas). In some way it likes a model
with big and small balls.

In what way I can define Radius?

Defining potential or using some atom_style like "granular",
"ellipsoid" with command shape? As I understand "shape" command is
used only for defining inertia tensor

Atom style granular defines a radius. The colloid potentail uses
the shape of the particles to define diameter. 100 to 1 is quite
extreme, so good luck
