In my system, I am defining torque on a body as function of the angular velocity of that body in transient analysis.

Is there any variable where the angular velocities of the different bodies in a model get saved, that I can grab and use in my equation for torque/moment in the transient model

So during the transient you want to retrieve the current angular velocity and then update a torque value? There's no variable that contains the current angular velocity so it will need to be done indirectly. You can add a small point mass to your model and then query the current rotation of the point mass. Then you can compute the current angular velocity as (current_rotation - previous_rotation)/(time step).
