Use Global coordinates.

Axisymmetric calculates Normal stress in 3 directions: Radial (Global X), Axial (Global Y) and Hoop (Global Z).

The formulation of an axisymmetric model is implicitly in a cylindrical coordinate system because the Z direction is the tangential direction which we call Hoop because if you follow a point in that direction it goes around the circle and forms a hoop.
