Coriolis effect in ANSYS

[AnPham]

I have a problem about active Coriolis effect in ANSYS Workbench.
The geometry is circular tube and applied Rotation Velocity about Z-axis via command: OMEGA,,,3000

I tried with 3 cases:
1. Active Coriolis effect with Reference Frame = ON (Stationary Reference Frame) -- "coriolis,on,,,on"
2. Active Coriolis effect with Reference Frame = OFF (Rotating Reference Frame) -- "coriolis,on,,,off"
3. Deactive Coriolis effect -- "coriolis,off"

The results show this:
Case 1: all results equal zero (deformation, stress, force reaction,...)
Case 2 and case 3: all results are same.

Is it correct? If not, why?
Thank you.

I attached the ansys project. Version 18.0

I have little experience in rotordynamics but I have written codes for beam elements that include Coriolis terms due to vibration and internal fluid motion and flow so then this term comes in the damping matrix that is present in dynamics.

See this and the theory manual for a description of the eom including Coriolis terms.
