The calculation of 3D high-frequency electromagnetic fields during induction heating using the BEM

A numerical 3-D-calculation method for the simulation of the electromagnetic field for different applications of high-frequency induction heating is developed. The calculation program uses the boundary-element method (BEM) and runs on an efficient personal computer. The setup to be considered is divided into groups of bodies with specific material properties which allow the formulation of simplified conditional equations for the electric vector potential at the surfaces of the setup components. Some examples of numerically calculated high-frequency current distributions indicate the efficiency of the program developed.<
