Computer simulation of induction heating processes

Induction heating computer simulation is a powerful tool for process design and optimization, induction coil design, equipment selection, as well as education and business presentations. The authors share their vast experience in the practical use of computer simulation for different induction heating and heat treating processes. A comparison of simulation versus the experimental ''trial and error'' method is discussed. The importance of accurate description of material properties for obtaining adequate results of simulation is also discussed. A ''Rule of Pyramid'' strategy for efficient use of computer simulation is described. This rule states that a designer should begin process or coil development with a simple program and progressively move to the more complicated and time-consuming software. This method reduces the time and effort required for induction heating process design. Examples of computer simulation for induction heating process design are presented.
