In the appropriate coordinate sys-tem, symmetry reduces the dimensionality of the equations from three to one or two, eliminating much of the computational complexity. Many of the standard electromagnetics examples are symmetric in spherical or cylin-drical coordinates, rather than in the Cartesian (rectangular) coordinates
