Our Community Vision

The OpenRadioss Community believes sustainability-driven complex technical challenges are best addressed within an open, collaborative software framework. By combining the best minds in the world and giving them the tools and environment to make innovative, groundbreaking improvements to products, processes, and workflows, OpenRadioss gives users the power to make the world a safer, greener place.

OpenRadioss™ User Community Events

Since launching in September 2022, OpenRadioss has already established a growing community of users across industry, academia and research.

The first in person and virtual user workshops event was held in Paris in November 2022, and the second in Aachen in June 2023, a selection of the presentations made at the events can be found here:
