Axisymmetry is symmetry under rotation over the toroidal (i.e., cylindrical) angle φ over an arbitrary value.
Axisymmetry is the basic assumption underlying the Grad-Shafranov Equation for the calculation of tokamak equilibria. This symmetry can only apply in an approximate fashion due to the fact that the external field coils are always discrete.
