This example consists of a iron magnetic core driven by the two radial magnet sources.
The structure generation is quite easy. To construct the vacuum solids which are further used for the definition of the radial magnet sources, one needs to define a cylinder first, slice it into four parts and delete two of them. The creation of the nonlinear iron magnetic core starts with the definition of a cylinder and a brick, which are added to one shape. Finally, two radial magnet sources are defined by assigning the magnet properties to the cylinder segments.
The simulation is executed with a tetrahedral mesh which is subjected to the adaptive refinement during the solver run. To perform the simulation, all the default solver settings are leaved unchanged. In order to reduce the overall computational time, three symmetry planes have been defined.

Both magnets share the same definition of the radial magnetization. |
After the calculation, the magnetic flux density and the material distribution fields are available in the "2D/3D Results" folder. Additionally, in the "1D Results"folder, one can find the simulation curves describing the mesh adaptation process.
