The work on the further development of Manatee software is going on with great steps. We are approaching the third major release of Manatee V2.2 which will introduce new features and modules, including the possibility to simulate induction machines. Besides the current modules for electrical and mechanical engineers, acoustic engineers will now find sound quality features and new noise reduction techniques, such as skew pattern optimization.

Are you eager to learn more?

  1. Follow our LinkedIn communication very carefully in April. The release of Manatee V2.2 will be announced here shortly.
  2. Attend our live demos during Manatee e-NVH Application Days on April 5th, because some surprising features will be revealed!

How to improve the correlation between tests and simulation?

The "zero prototype" or "first time right" mottos were probably not invented by real-world engineers... At EOMYS, our experience shows that building a realistic and comprehensive virtual prototyping workflow of acoustic noise and vibrations due to electromagnetic excitations requires several iterations between tests and simulation.

Magnetic noise and vibrations (called "e-NVH" in automotive applications), is indeed sensitive to electrical, magnetic, mechanical, acoustic and heat transfer variables. What makes it even more difficult to correlate simulation models with reality are strong interactions between the physics. There are several reasons why your e-NVH simulation results, even run with Manatee software, will NOT match with the absolute values of your test results at the FIRST simulation run.

New team members

At EOMYS we are happy to welcome two new internships we can introduce here to you.
Pierre Gailliez carries out his studies at Arts et M├ętiers ParisTech. During his final year 6-month internship at EOMYS, he works on PYLEECAN open-source software electrical models.

Antoine is a student in Applied Mathematics at the University of Lille, he joined the EOMYS team for his Master 2 internship. The purpose is to implement some magnetic reluctance networks in the open-source software Pyleecan.
