The method is useful for detailed analysis of nonlinear motion, which in many cases is strongly influenced or even dominated by the presence of fringe fields. The use of the symplectic scaling method typically speeds up the computation of fringe field effects by around two orders of magnitude and thus approaches speeds similar to that of the main field calculation. The method has been implemented in the code COSY INFINITY; several examples from various subfields of beam physics are given to illustrate accuracy and speed of the method.
