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
