In this work we survey our research on domain decomposition and related algorithms for large power electric cables and the impact on the human health. The equations that describe the behaviour of the fields in electromagnetic devices are coupled because most of the material properties are temperature dependent and may depend on temperature in a nonlinear way. More, any power loss is transformed in local heating so that the heat source in the thermal model is the Joule-Lenz effect of the electrical current. Here we assume that the sources of the magnetic field have sinusoidal time dependence and we neglect the effects due to the displacement currents. The target example is from the electric engineering. It is a large power cable in a free space. General symmetry of the device can be used for efficient software. The algorithms for analysis are presented in the context of the finite element method. The results can be extended for simulation of distributed-parameter systems described by elliptic and parabolic equations. The domain decomposition at the level of the problem is used. In this way the coupled magneto-thermal problem can be analyzed by a reduction of the computational effort.
