For axisymmetric models, we use cylindrical polar coordinates (r, θ, z) with no variation in the θ direction. So we can just model a slice in the (r, z) plane as shownbelowshown below.
In ANSYS, the radial direction is x (rather than r) and the axial direction is y (rather than z). Confusing! We recommend that in an axisymmetric analysis, you think of the directions in ANSYS as radial & axial rather than "x" and "y".
