moving sphere in a confined space with static fluid

Dear all,
This should have been a simple simulation. One solid sphere moves in a confined space where the surrounding fluid was static, but due to the movement of the sphere, fluid should have some motion. I want to know the drag force this sphere has from the fluid.
I used the FSI module and set the sphere with a velocity of 4um/s, while the inlets and outlet of the fluid phase were all 0 Pa. Run it with a transient solver.
I didn't see any error, and the sphere seemed to move but no flow caused at all and the sphere didn't have any stress on surface.
I suppose I set some boundary condition wrong? Anyone could help me?
Thank you very much.
