1. Example #9 Integrated Magnetics Example
Designing a new 42-volt automotive power system requires knowledge of components, electronics and controls. It has become a truly multi-disciplinary engineering task. Ansoft's Electromechanical System Design Suite is a powerful combination of software simulation technology including electromagnetics, circuits, block diagrams, state machines, and specialized design programs which allow an engineer to successfully design and analyze a complete 42V system from start to finish.

2. Open PExprt Modeler [PEmag] application
This example shows how to setup and solve an Integrated Magnetics model, which has windings on all three core legs.
Note: In the Maxwell Projects panel, create a PEmag project instead of a PExprt project.
Integrated Magnetic models cannot be generated from PExprt

3. Select File/New for a new project
Opening PEmag from Maxwell Control Panel, a new project is opened by default
