This example demonstrates a calculation of the eddy currents appearing in the four conducting tubes (5.8e7 S/m) excited with the time-harmonic currents and voltages. The driving frequency of the sources was chosen to be 50 kHz in order to clearly illustrate the eddy currents phenomenon.
The structure generation is quite easy: the first conductor is created using a brick, all the other are obtained by just applying the transformation technique. The current and the voltage paths are defined from the geometrical curves. In order to reduce the overall simulation time, one symmetry plane is defined.
The simulation is executed with a tetrahedral mesh. For the solver run, only the adaptive meshing option is switched off, all the other default settings are left unchanged.
After the calculation, the conduction currents ("eddy currents") as well as the magnetic flux density are available in the "2D/3D Results" folder.
