This example shows how to analyze a simple loss-free transformer. In this case all transformer's parameters (e.g. inductances) can be extracted in a single run. For this purpose the driving currents of both coils are shifted in phase by 90 degrees to each other.
The structure generation involves the creation of a cylinder and a couple of rotation and extrude operations to create the yoke. The second coil is derived from the first one by a transform operation. Afterwards its name and coil parameters were adjusted. Specifying the yoke's radius via a parameter allows for parameter sweeps later on.

The structure's mesh is refined using the global "Lower mesh limit" parameter a volume refinement inside and around the yoke. To perform a simulation, the default option of the adaptive mesh refinement has been switched off.
A couple of post processing templates have been defined in order to extract the transformer's inductance matrix and the coupling factor between the coils. Some material and geometric properties are already parameterized so the next step might be to start a parameter sweep and observe how the coupling factor changes with a certain parameter.
