Angular Velocity Unit - Rotational Diffusion

Dear LAMMPS Users,

I'm calculating the angular velocity of a rigid body using "omega(group,dim)" variable function. I just want to be sure that the unit is "rad/fs" using real units.
Furthermore I want to know if there is a way to calculate the rotational diffusion coefficient (for example using "comute msd" or "compute vacf" for the rotation)

Best Regards


For the first question, check the documentation for the “units” command. It should be mentioned there.

I don’t know about the second.
