How to add different types of atoms in simulation

Hello,

I want to use spheres and one superquadric (cylinder) in my simulation. However, it turned out to be illegal when I tried using two types of atom (atom_style granular; atom_style superquadric).

I know I can still use superquadrics to represent sphere (just set both "blockiness" as 2), but, in this case, the rotation is not updated and the angular velocity is always 0.

I use nve/superquadric (scheme 1) for integration:

fix integ bed nve/superquadric integration_scheme 1

So, how should I deal with either problems?

Thanks
