1h simulation allows to test performance of a new-designed coil virtually, saving time and money for building it. Preparation of the model takes less than 1 hour. The geometry is uploaded to CENOS platform as two CAD files in .step format from a CAD software. The inductor and the workpiece were meshed automatically, just defining skin-depth parameters and a size of maximal element. The induction heating method is very efficient for hardening of steel parts in automotive indu
