2D motion (rotation)

I am using Comsol Multiphysics V4.
I am trying to build a model where a oval rotates. Then I will add a flow-solid interaction in order to analize how this motion affects the flow (Diesel).
The problem that I have is when I am setting up this motion.
I have created a 2D Solid Mechanic time-dependent model. Then I have drawn a rectangle and a elipse inside. The next step is from an union and then apply materials and meshing.
I have set up "w" as angular velocity with a 1[rad/s] value in global definitions and then, in initial value I have specified Velocity fied -y*w for X and x*w for Y. I have also tryed to specify this angular velocity as prescibed velocity with the same result.
The solver seems Ok but when I plot my 3sec. analysis I can´t see any motion in the elipse.
I would really appreciate some help with this problem.
Thanks

I'm trying to have a 2D object in a shear flow, where the object can rotate freely (it's being pushed about its axis by the fluid). Any idea how to set such a simulation up?
Thanks!!
