    Hard-coupled model of induction heating of a ferromagnetic disk is presented. The problem is described by three coupled partial differential equations (for the distribution of electromagnetic field, temperature field and field of thermoelastic displacements) whose coefficients are temperature-dependent functions. The system is solved numerically in the monolithic formulation by a fully adaptive finite element method of higher order of accuracy implemented into own codes Hermes and Agros. The methodology is illustrated by a typical example—heating of an active wheel of a high-speed gas turbine that is to be hot-pressed on a shaft with the aim of obtaining a shrink fit allowing transferring the given torque at the nominal revolutions. Evaluated and discussed are also the parameters of the heating process in transverse and longitudinal magnetic fields.
