Time dependent axis of rotation

Hello, Dears
how i can define time dependent axis of rotation in my transient-rotor-stator domain ?
cfx(transient run) > TRS domain > Domain motion > angular velocity axis.

You can try making the axis definition a function of something but I am sure it will not work - as soon as you move the rotational axis it will introduce all sorts of gyroscopic forces and I am sure they are not included in the solver. And to prevent this occurring the solver does not allow you to make the axis definition a function of time.
