simulation ring at centrifugal force

Hello,

I want to simulate a ring (Ø100 x Ø90 x 20) rotating around his axis.

I  have a problem to find the correct constraints because the ring is axially not fixed.

I will compare the result with an analytical solution. If it fits together then I will change the geometry to a more complicated one.

What is the right configuration of the constraints?

Thank you

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Thank you,

the result in radial direction is ok.

The displacement in axial direction is 0 on the inner surface, which is fixed by the constraint.

How can I avoid this?

Simplify to quadrant of the geometry.

This permits placement of Frictionless constraints on cut faces.

Checkmark - Remove rigid body modes...

Edit: I would probably increase the Mesh density too.

Edit 2:  Never mind - I was thinking pressure, not centrifugal force.  My mistake.

Thank you,

I foolwed your suggestion, but the result is not correct.
