Certain numerical computational methods or software are preferred for each family of induction heating applications. There is not a single universal computational method that optimally fits all types of applications. In recent years, the finite element method (FEA) became the dominant numerical simulation tool for a variety of engineering applications. Though FEA is a very effective modeling technique, it is not the ultimate computational tool for all induction heating applications. In some cases a combination of alternative methods is more effective. Article provides a short comparison of different computer modeling techniques used to simulate induction heating processes. Case study of computer modeling of FluxManager Technology is provided here as well.
