A mesh accounting for the skin depth needs to be generated to perform a magnetic field frequency response analysis. The time varying phenomenon of the magnetic flux penetrating the heated workpiece using induction heating needs to be taken into account when the temperature of the workpiece exceeds the Curie point. This presentation indicates guidelines to generate optimal mesh by investigating the effects of the mesh density on the heat generation using a workpiece and coil with simple geometry. In addition, the analysis results using the guidelines for generating
mesh are compared to actual testing results.
