Abstract :
A method for the solution of high frequency three dimensional coupled magneto-thermal problems such as those of the induction hardening of steel is proposed. The magnetic problem Is treated first using the Boundary Element Method (BEM) to calculate magnetic parameters. From eddy-currents and Joule effects, source values are obtained to solve the thermal problem by the Finite Element Method (FEM). The two problems are then indirectly coupled to obtain a solution for the entire problem
