Simulation-Based Optimization of Inductive Heating Processes and Components
Simulation can determine optimal heating or generator parameters, design complex inductors for inductive heating processes, or uncover weaknesses in existing inductors.”

In most areas where there are multi-physical phenomena (in the case of induction heating electro-magnetic, thermal, and sometimes even fluid dynamics), numerical simulation has become indispensable. Simulation software is an important tool, especially if a coil geometry is complex. Simulations can save time, costs, energy, and resources.

For example, in coil manufacturing, there are oftentimes multiple restrictions in terms of temperature distribution in the workpiece, geometry of the induction coil and desired resonant frequency to match with the circuit of the induction generator. This leads to many coil candidates, and it would be very time consuming and costly to build and test them all. The accuracy of simulations even allow virtual coil design.

Thanks to additive manufacturing (for example SLM – selective laser melting) there are less restrictions, and the theoretically best coil geometry can be built – again and again, with the same quality (and high reproducibility).

Furthermore, the visualization of fields such as current distribution, magnetic field and of course the temperature distribution in the workpiece strengthens the understanding of the underlying physics and leads to higher product quality.
