Open source FEA (finite element analysis) software have traditionally been associated with academic and research environments. However, recent trends demonstrate significant adoption across a wide spectrum of industries, including energy, aerospace, electronics, and construction, where organizations are leveraging open source FEA to address complex engineering challenges while avoiding the costs and restrictions of proprietary licensing of Ansys and other commercial FEA systems.
This material continues my previous article Open Source FEA Software as an Accessible Alternative to Ansys and Nastran (Linkedin Pulse copy ) and highlights notable examples of open source FEA industrial implementation, its expanding influence, and strategic advantages for businesses of all sizes.

Électricité de France (EDF) has played a pivotal role in advancing open source FEA tools, releasing its platforms under open source licenses since 2005. In 2024, EDF established Simvia as a separate business unit to further develop and commercialize these solutions. Simvia's Code_Aster members community now includes not only similar energy companies from other countries (such as Hydro Quebec and Andritz Hydro) but also leading companies from other sectors, including Airbus Group, Rolex, Valeo, Egis Group, and Holcim Group.
When restructuring Simvia into a separate business unit, they published a collection of case studies that illustrate the breadth of industrial applications of their software.
Holcim Group (LafargeHolcim), a multinational company manufacturing building materials, leverages Code_Aster to predict early-age concrete temperatures in massive structures , ensuring compliance with thermal criteria for durability.
