This is an example of heating an entire cylindrical conductor by moving it and using induction heating. By passing through the center of a coil connected to an AC power source, eddy currents flow on the surface of the conductor, generating heat. The temperature rises from the surface, and heat is conducted inward. Due to the axisymmetric shape of this model, it can be analyzed using 2D axisymmetric analysis.

3D high-frequency electromagnetic field analysis software using the finite element method (high-frequency electromagnetic field simulator) with a module for frequency response analysis. ■□■Features■□■ ■Since it is integrated with the PHOTO series pre- and post-processing, data creation, analysis, and result processing can be performed as a series of operations. ■It is integrated with other PHOTO series modules, allowing for easy coupled analysis, such as deriving temperature distribution from heat generation obtained through electromagnetic field analysis. ■A revolutionary speedup has been achieved by combining the edge element method and ICCG method. Therefore, 3D electromagnetic wave analysis (high-frequency analysis) can be performed on a personal computer. ■Since it uses the finite element method, it is suitable for analyzing closed regions, especially those involving multiple media. ■When coupled with the thermal conduction analysis software PHOTO-THERMO, it is possible to calculate temperature distribution from heat generation within dielectrics.
