The joint laboratory between Altair Engineering and G2Elab was created in 2017 and is working on developing the Flux software suite. It has been used in industry to simulate electromagnetic fields and help design all kinds of electrical machines.
In late November 2021, the CNRS organised a communication event based around its joint laboratories, at Palais Brogniart in Paris. Minister for Higher Education, Research & Innovation Frédérique Vidal cited the exemplary success of the Flux software suite, a result of the work of G2Elab (CNRS, Grenoble INP – UGA, UGA). 40 years ago, this software entered the industrial world, and it is now marketed by Altair Engineering, an international leader in engineering simulators with a joint laboratory with G2Elab.
With 2,000 users across 750 industrial sites, Flux is currently the third biggest program in the world for simulating low-frequency electromagnetic fields. Engineers use it to simulate electromagnetic fields produced by all kinds of electrical devices. “Electrical machines convert electric energy into mechanical energy,” explains Olivier Chadebec, CNRS researcher at G2Elab. “This conversion relies on a kind of intermediate energy, electromagnetic energy, which is important to quantify in order to evaluate the performance of the machine. The simulation software makes it possible to construct a digital copy of the machine and calculate the low-frequency electromagnetic fields that it generates, without having to actually build it. This makes it possible to make as many adjustments to the parameters as needed, before making the machine in real life.”
