Abaqus : Wheel Rotation Problem

Abaqus : Wheel Rotation Problem

Abaqus : Wheel Rotation Problem

(OP)
Dear All

I try to rotate my wheel on the rail.
I constraint my wheel with respect to reference point (using Coupling or Rigid Body) and give the RP a rotation.
But the result shows that the wheel is growing. ( Deformed)
I try to change the deformation scale factor in Options => Common
If I change to auto-compute, the wheel didn't deform but it would not contact with the rail.
( When I give more rotation, the wheel will lift up more and more)
And if I choose to uniform and give 1, then the wheel will be growing.

So I have no idea what it happens.

Here is my model file.
