I am simulating using ANSYS Workbench (14) a heated rotating tank setup which is two concentric thin cylinders with water in between and temperature boundary conditions at the bottom.

The setup looks like a rectangle in the axisymmetric swirl situation. I've set the cell zone to have a rotating frame motion.

The FLUENT tutorial guide suggests that the walls must be stationary for such a rotating tank whereas the help file explicitly states that it must be set as a moving wall (which implies a zero angular velocity relative to adjacent cell zone)

Which one is correct?

Also, for an open top, I've set it as a zero shear boundary. Is it appropriate?

Please mention the corresponding initial conditions as well.
