New Software From Altair Subsidiary

TROY — The engineering technology developer Altair announced the release of version 12.3 of its Flux software for low frequency electromagnetic and thermal simulation.

Flux is intended for the analysis, design and optimization of modern applications such as electric rotating machines, actuators and sensors, high power electrical equipment, heat treatment or electromagnetic compatibility.

The company said the new version offers several enhancements:

* Co-simulation with solidThinking Activate, Altair’s software for model-based development system simulation. Flux embeds its own electric circuit editor but when it requires more advanced analysis this co-simulation is of great help. The coupling considers various phenomena, such as motion, control loops, system interaction, and more.

* More precise evaluation of the heat transfer, through a new coupling with Altair AcuSolve, a computational fluid dynamics solver included in the Altair HyperWorks suite.

* New coupling with OptiStruct, Altair’s structural linear and nonlinear solver, which allows the calculation of vibrations generated by electromagnetic forces in electric machines to reduce their noise.

* New robust and fast 3D mesh generation tools.

* Easy 3D induction machine tool setting.

* 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.

* 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.

“Flux now benefits from the latest technologies available in Altair, ensuring added value for our users,” said Vincent Leconte, director of business development for electromagnetic solutions at Altair. “We have integrated new CAD import and meshing capabilities and speeded-up 3D model creation. Offering new connections with the other Altair simulation tools allows users to couple different physics and propose a complete simulation solution. With Flux 12.3 we have opened the door to multi-disciplinary optimization for design in electrical engineering,”

Privately held with more than 2,000 employees, Altair is headquartered in Troy, and operates more than 50 offices throughout 22 countries.  Altair serves more than 5,000 corporate clients across broad industry segments. To learn more, visit
