EM NVH Force Mapper

1.0

To facilitate the NVH analysis of electric motors, Ansys has developed a guided workflow for the most important simulation step: the coupling between the magnetic and mechanical domains. This application enables engineers to collaborate, calculate, and map the forces in a reliable, robust way, including checking force accuracy.

At the beginning of the workflow, you must provide an existing project from the Ansys Maxwell advanced electromagnetic field solver. After you provide all the relevant inputs for NVH simulation, they will be used to automatically set up the project in Maxwell software, using PyAnsys behind the scenes. The tool will also verify whether the mesh quality is adequate for NVH simulation, as the force calculation accuracy is very mesh-sensitive. Once this process is complete, the forces will be calculated and displayed in the tool, which enables you to visualize the force plots.

Next, you can provide the project from Ansys Mechanical structural finite element analysis software, in which the forces will be applied. Every step is enriched with comprehensive documentation. This workflow is an application with a dedicated user interface (UI), automation scripts, and postprocessing capabilities. The application will automatically initiate and manage processes in Maxwell and Mechanical software, but it also offers third-party file support.

By using this workflow, engineers can follow the documented steps in a collaborative way, ensuring that the setup of the Mechanical project has accurate electromagnetic loads. Many configurations are supported, including skewing, symmetries, and importing measured data.
