Multi-domain simulation tool supports multi-Disciplinary optimization

May 11, 2017 // By Julien Happich
Now a part of the Altair HyperWorks simulation platform, low frequency electromagnetic and thermal simulation software Flux now comes in its 12.3 version, including several new enhancements for users to achieve even higher quality meshes and experience new and efficient ways to deal with 3D CAD imports.

Flux 12.3 allows co-simulation with solidThinking Activate, Altair’s solution for model-based development system simulation. Flux embeds its own electric circuit editor but when it requires more advanced analysis, it can leverage this co-simulation. The software also allows a more precise evaluation of the heat transfer through a new coupling with Altair AcuSolve – an accurate computational fluid dynamics (CFD) solver included in the HyperWorks suite.

Another coupling with OptiStruct, Altair’s structural linear and nonlinear solver, allows the calculation of vibrations generated by electromagnetic forces in electric machines to reduce their noise. The tool features new robust and fast 3D mesh generation tools, including a new volume tetrahedral generator and high quality meshing technology able to deal with complex geometries. Easy 3D induction machine tool setting, ensuring electric machine simulation in 3D, can be generated quickly and easily using the model templates.

Efficient optimization of electric systems, minimizing the losses in a device or system, improving the response times, increasing the torque and reducing dimensions and weight. For complex cases, the Altair HyperStudy optimization solution can reduce the computing time to a minimum with guaranteed accuracy of results, considering different physics, like reducing the noise of an electric motor interacting on the electromagnetic design.

A unique post-processing function has been developed to help predict dielectric breakdown voltages with better accuracy, allowing for reduction of the usual oversizing in such devices.
