Powerful, industry-proven finite element solver for dynamic event analysis – now available to all
For more than three decades, the world’s top industrial, research and development, and educational organizations have employed Radioss to solve complex linear and nonlinear engineering problems. Now, Altair is introducing OpenRadioss, open-source software designed to bring together a worldwide community of experts and users to make the world a safer, greener place.
Welcome to the OpenRadioss Community
Altair Radioss is an industry-proven analysis solution that helps users evaluate and optimize product performance for highly nonlinear problems under dynamic loadings. For more than 30 years, organizations have used Altair Radioss to streamline and optimize the digital design process, replace costly physical tests with quick and efficient simulation, and speed up design optimization iterations – all so users and organizations can improve product quality, reduce costs, and shorten development cycles.
Introducing OpenRadioss
OpenRadioss is the publicly available open-source code base that a worldwide community of researchers, software developers, and industry leaders are enhancing every day. OpenRadioss is changing the game by empowering users to make rapid contributions that tackle the latest challenges brought on by rapidly evolving technologies like battery development, lightweight materials and composites, human body models and biomaterials, autonomous driving and flight, as well as the desire to give passengers the safest environment possible via virtual testing.
With OpenRadioss, scientists and technologists can focus their research on a stable code base under professional maintenance that benefits from the large library of existing finite element capabilities (Key Features) and the continuous integration and continuous development tools provided to contributors.
If you are interested in simulating automotive crash and safety, shock and impact analysis, electronic and consumer goods drop testing, and fluid structure interactions, then OpenRadioss is for you. OpenRadioss lets users make efficient, robust predictions of combined multiphysics behaviors in complex environments by relying on advanced MPI and OpenMP parallel structure, which provides industry-leading scalability regarding large, highly nonlinear structural and multiphysics simulations.
Users can also run LS-DYNA® * model input format directly in OpenRadioss. Community members are working to enhance and share LS-DYNA® model input and develop interoperability with other popular explicit solvers.
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, a selection of the presentations made at the event can be found on the new presentations page of the site.
The second user event will be held in Aachen in June 2023, you can register to attend here:
