Ansys Mechanical 14.0, Axi-symmetric condition in Ansys Mechanical?

How to apply pressure on the inner surface of the wall of cylinder, in such a way that every point on the inner surface will have the uniform pressure?

As you can see from the diagram, I have two different geometry, the stent and balloon. The balloon is the cylindrical shape object, which is inserted into the stent. I want to create a simulation, in which I apply the load on the inner surface of the balloon, then the balloon will expand, which in turn expand the stent.

Just apply Pressure on the inner wall and select it to be Normal to surface.

STEPS:
1-Select 'Static Structural" in outline
2- Apply Loads> Pressure
3- Select inner wall and Apply pressure this to it.
4-In Details of Pressure select "Define By = Normal To"

You are done!
