In this paper, we simulated the heating of a work piece by coupling two heat sources. Concentrated solar energy was applied at the bottom of the work piece, which generated a heat flux from the parabolic solar dish concentrator. Subsequently, induction heating was applied, which generated Eddy currents that circulated through the work piece and heated the surface of the material. A numerical simulation for solving Maxwell's equations and coupled (AC/DC Module) and transient heat transfer conditions (Heat Transfer Module) was developed using COMSOL Multiphysics®. In this case, the magnetic field and temperature distribution of a cylindrical magnetic metal was obtained for two dimensions, and the heating time of the work piece was also determined.
