[lammps-users] rotational damping

Dear Lammps users,

Can anyone tell me if there is any rotational damping for extended
spherical (granular) particles? I don't think it's included in the
fix viscous code. Also, does anyone has any knowledge of how to
include anything to restrict rotational movement, such as a rotational

Fix nvt/sphere (and npt/sphere) thermostat the
rotational degrees of freedom. Something
like that would have to be added to fix viscous.
