Abstract :
Heating by induction causes interference by electromagnetic and thermal phenomenon. The modelling of the problem is based on Maxwell´s equations and the equation of heat. This article presents a method of numerical simulation coupling the calculation of physical process evolving in the material in the course of heating. An algorithm for indirect coupling is developed for resolving the problem of calculation time important for a big agreement between the thermal and electric constants. This method is implemented for the 2D case in the MATLAB environment and utilises the tools in the PDE block. An example application is illustrated by the modelling and simulation of reheating of an aluminium billet
