PLANO, TX, June 30, 2026 – ORECA Group uses Siemens Simcenter for racing vehicle simulation work tied to the Le Mans 24 Hours with Ford Motor Company. The software replaces ORECA’s legacy CFD environment and supports CFD, multiphysics analysis and composite structural optimization across its motorsport engineering workflow.
The group is using Simcenter STAR-CCM+ for CFD workflows and multiphysics simulations that combine aerodynamic, thermal and brake-related effects. It is also using Simcenter Optistruct to optimize carbon fiber composite layups and balance stiffness and weight in performance-critical components.
“ORECA was looking for a simulation environment that could support accelerated and more streamlined workflows from design through simulation while enabling new types of multiphysics analysis,” said Jean-Philippe Pelaprat, head of aerodynamics, ORECA Group. “Siemens’ simulation software gives our engineering teams the flexibility to run more advanced simulations and optimize composite structures in a highly demanding motorsport environment.”
“Our collaboration with ORECA shows how Siemens Xcelerator empowers engineering organizations to push the limits of performance through simulation-driven engineering,” said Sam Mahalingam, executive vice-president of Simulation, HPC and AI, Siemens Digital Industries Software. “By bringing advanced CFD and composite optimization together within a digital twin environment, we’re giving customers the tools to explore bold new design approaches and drive innovation in some of the most demanding, competitive engineering programs in the world.”
The collaboration fits into the digital twin and software-driven engineering approach for motorsport. The same methods are also used in automotive and manufacturing, where engineering teams face performance and time-to-market constraints.
