I would like to make some group of atoms rotate around some axis in the system, can Lammps do this? Thanks.

You'd have to write a fix to do this.

Hi Jarvis,

I suggest you write a new fix that adds centrifugal forces to atoms in that group. That fix would have the mask POST_FORCE and override the post_force() function from Fix. You may want to look at FixLangevin to see how forces are added to atoms in a group.

Cheers,
