After you run the simulation, you can pre-select the axis of revolution. Then plot stress component, SY.
The stress component mapping with an axis selected is: SX = radial stress, SY=hoop stress, and SZ = axial stress.
You will likely need to insert an axis directly on top of the temporary axis. To do this, choose "View...Temporary Axes". Then "Insert...Reference Geometry...Axis".
Hope that helps.
I will give it a try.
