What is the difference between Manatee and multiphysic numerical software suites (e.g. Ansys Workbench, Comsol Multiphysics, Siemens Simcenter)?

Manatee® is a complementary software service that helps you getting the best out of your current CAE software to efficiently solve magnetic noise and vibration problems. Manatee® is not designed to replace electromagnetic, structural mechanics or acoustics FEA software. This is why all Manatee® customers already have licenses from Ansys, Siemens, Altair or Hexagon.

Special problems require special tools to be efficiently adressed. Manatee® is the only software specialized on the simulation and analysis of magnetic noise and vibrations induced by electrical machines operation.

The following table summarizes the comparison between Manatee and some other CAE tools:

The advantages of Manatee® compared to multiphysic numerical software suites (e.g. Ansys® Workbench, COMSOL Multiphysics®, Siemens Simcenter™) can be summarized as following:

  • pre-defined multiphysic couplings (no need to define how to couple electromagnetics, structural mechanics and acoustics) to shorten simulation set-up
  • adapted modelling levels for use during both early electromagnetic design iterations (NVH ranking of e-machines in a few seconds of calculation) and detailed structural design (optimized coupling with structural FEA)
  • advanced NVH troubleshooting tools with more than 50 visualization tools to understand the root cause of noise and vibration
  • direct implementation of main noise mitigation techniques as well as manufacturing tolerances
  • proprietary algorithms to speed up calculations and give more physical insights, including Electromagnetic Vibration Synthesis, and Magnetic Look Up Tables
  • more reliable results due to control of parasitic harmonics introduced by spectral leakage, meshing, magnetic force interpolation or field projection
  • user-friendly GUI made to ease collaboration between electrical, mechanical, acoustic, and NVH test engineers
  • more than 150 industrial validation cases including sound power level at variable speed, as well as academic validation cases
  • a unique e-NVH support by our e-NVH experts coming with all leasing licenses
