Instructors: Didier Zefack

Didier, expert of JMAG software, has more than 6 years’ experience in electric machine design using the FEA method with JMAG. He has given numerous training courses and is also daily supporting JMAG users in electric machines design and other areas.


Shape optimization is an old, classical and ubiquitous field of eMotor design & research, which has inspired deep mathematical theories as well as numerous crucial applications in industry and engineering. In recent years, topology optimization that can significantly change the geometry itself has been attempted, and novel designs heretofore not considered are being created. JMAG can obtain topology optimization results in a short time by executing topology optimization using sensitivity analysis.

This training will provide to a new and advanced JMAG users a general overview of Topology optimization features. From the decomposition of the design regions to the analysis of results, all functions will be explored. Some general application examples and exercises will be used during the training. The training will be a mix of presentations and demonstrations, the exercises will be provided to the attendees and will be checked during the next sessions. The participant can also use their own model to follow the training.
