Piezoelectric gyroscope setting

Hello, I'm simulating the Coriolis force effect on a piezoelectric vibrator in order to detect the angular velocity motion. I think I set propoerly the demanded boundary conditions to provide Drive mode (ossilation/vibration mode) using AC signals (Vsin(2pift) defined in Terminals with domin frequency study. However when applying the rotating frame considering Corilois force and centrifugal force , Effect of Corilois force does'nt appear only under very hight input value of angular velocity (500 rad/s). Using 500 deg/s input rotationg frame, sensing voltage do not change as if Corilis force doesn't been generated.
Do we need a special setting of the solver under domain frequency study when detection angular velocity? or there is something wrong in boundary conditions?
I would be really grateful if somebody could help with this. Sincerly
