Radioss is one of the most advanced and established explicit solvers for simulating complex dynamic phenomena. For over 30 years, it has been a benchmark for engineers and designers dealing with highly nonlinear problems such as crashes, impacts, explosions, and high-velocity collisions.
Widely used across automotive, aerospace, electronics, defense, and biomedical sectors, Radioss significantly enhances impact resistance, safety, manufacturability, and product maintainability.

The software provides highly accurate simulations of high-energy scenarios such as car crashes, aircraft ditching, ballistic tests, electronic device drops, and detonations—delivering robust and reliable predictions.
Thanks to its scalable architecture and multiprocessor capabilities, Radioss handles large-scale models efficiently, maintaining computational performance even in the most demanding simulations.

Radioss is widely adopted by leading R&D centers and major industrial organizations. Its effectiveness is recognized not only for numerical accuracy, but also for delivering actionable insights for structural design and optimization.
In the automotive industry especially, Radioss has played a pivotal role in advancing crashworthiness simulations, supporting the development of safer and more innovative vehicles.

Similarly, the aerospace sector leverages Radioss for simulating extreme scenarios such as bird strikes and emergency water landings. In defense, it is used for evaluating the effects of blasts and ballistic penetration on vehicles or protective structures.
This wide application spectrum confirms Radioss as a versatile multiphysics solution for complex engineering environments.

Radioss is designed to fully exploit parallel computing architectures, offering one of the best scalability levels in the industry for strongly nonlinear simulations.
It is ideal for large-scale projects requiring high computational power—such as overnight crash simulations of full vehicles or battery-pack and chassis interaction analyses in electric vehicles.

Radioss integrates seamlessly with Altair HPC solutions, enabling efficient model execution on local, cloud, or hybrid infrastructures. With a unified licensing model, users can access the full Altair platform—including solvers and optimization tools—without disruptions or technical limitations.

One of Radioss’ key strengths is its ability to solve complex multiphysics problems reliably and efficiently.
The software allows simulation of interactions among mechanical structures, fluids, thermal phenomena, and electromagnetic fields, all within a unified computational environment supporting both linear and highly nonlinear dynamic analyses.

Radioss integrates natively with other tools in the Altair suite—such as OptiStruct for structural optimization, MotionSolve for multibody dynamics, and HyperMesh for pre-processing. It is also compatible with many third-party solutions, offering full flexibility to fit into existing engineering workflows.

With over three decades of experience in vehicle safety, Radioss has transformed how OEMs approach virtual design and validation.
Its simulation accuracy, ability to include detailed battery pack models, and robustness in handling realistic scenarios—such as multiple impacts or structural penetration—make Radioss a strategic choice for designing safer, lighter, and higher-performing vehicles.
