Postprocessing Systems for Magnetics

Abstract

When a solver program terminates its run, it leaves in a computer file a digital version of the magnetic field as calculated. The postprocessor is expected to perform any further manipulations—which may be many, and which may involve far from trivial amounts of computation—and must therefore be endowed with the capacity for performing them. Some of the varied techniques available for the extraction of engineering information from mathematical solutions were examined at length in the previous chapter. However, no attempt was made there to provide an exhaustive list of all the operations that might be needed; the stress was rather on results which are common to many designers’ requirements. The present chapter is directed the other way: it seeks to ask how rather than why, and therefore to examine the implementation of a postprocessing system capa­ble of meeting the requirements implicitly defined by its predecessor.
