MeI is on a distinguished road

i am a ANSYS beginner and i got a question on creating an oscillating input in CFD.

imagine i have a box which full of water in it. At the bottom of the box i have a cirle which is a electronic plate and it keeps on oscillating with a frequence 50~80Hz.

what i learnt b4 is right click-> boundary->select the input surface-> and there are only 6 choices (normal speed, cart vel componet, cyl vel component, mass flow rate, total pressure, static pressure) but it seems not correct.

and i have read tutorial21....but it seems not what i want. Could anyone who can give me some step or the correct tutorial i have to go through.

The most accurate way of doing this is with a moving mesh appoach.
