Altair® RADIOSS® is a leading structural analysis solver for highly non-linear problems under dynamic loadings. It is highly differentiated for scalability, quality and robustness, and consists of features for multiphysics simulation and advanced materials such as composites.
RADIOSS is used across all industries worldwide to improve the crashworthiness, safety, and manufacturability of structural designs. For over 25 years, RADIOSS has established itself as a leader and an industry standard for automotive crash and impact analysis.
In the RADIOSS 2017 release, physics modeling capability has been expanded to include additional advanced material and failure laws. Improved simulation driven innovation was enabled by improvements to solver robustness and accuracy and strong ties to optimization. Computation performance has been improved such that 16300+ cores could be used to simulate a 10 million element full vehicle model. RADIOSS has become even easier to use with the addition of new automated ways to handle poor solid element quality and contact initial intersections. Ease of use was improved with new composite modeling input that better matches the manufacturing process.
