How do you model free surface of rotating water in 3D? (forced vortex formed at top surface) (solid body rotation of a fluid)

The top surface is in contact with air and I'd like to model the free surface on top of the water that is part of a forced vortex that forms (in a form of a paraboloid) as the water rotates.
I created an outer fixed domain and an inner rotating domain.
How do you model this 'solid body rotation' of a fluid in "3D"? (Laminar, rotating flow) (If possible, I'd like to avoid using 2D axial flow)
Do I enter velocity vector field using "Inlet"? What x y z vector should I enter in this case?
How do I set moving mesh velocity and decide which part does and doesn't move, if I had to use moving mesh?
Thank you!
