PSA Peugeot Citroën Uses RADIOSS to Run a Model with 15 Million Elements PSA Peugeot Citroën collaborated with Altair, Bull, PRACE and others to perform a study of automotive crash rupture simulations, investigating ways to improve material failure criteria and better predict cracks. Read the PSA Peugeot Citroën Case Study
Depuis plus de 30 ans, RADIOSS s’est imposé comme un leader et un modèle de l’industrie pour les crashs automobiles, l’analyse de chute et d’impact, les effets balistiques terminaux, les effets de souffle et d’explosion et les impacts à grande vitesse. Automobile, Aérospatiale, électroniques, les entreprises de défense et centres de R&D apprécient la contribution qu’il apporte à la compréhension et à la prédiction de comportements de conception dans des environnements complexes, tels que les accidents de voitures, les amerrissages d’avions ou les effets de souffle sur les véhicules. L’intégration étroite dans l’environnement HyperWorks fait de RADIOSS un outil puissant de conception. Les modèles RADIOSS sont conçus pour l’optimisation. Les transitions vers les solveurs d’optimisation OptiStruct et HyperStudy sont faciles.

Benefits

Scalability, Quality, and Repeatability

RADIOSS’ advanced multi-processor versions (Hybrid Massively Parallel Processing) have enabled the best scalability in the industry for large, highly nonlinear structural simulation. The use of Advanced Mass Scaling and single precision option speeds up orders of magnitudes while retaining the same accurate results. Detailed and accurate analysis can also be achieved without decreasing the global time step or increasing overall simulation time. Speed-up solutions like Multi-Domain, Submodeling are unique solutions to bring the right answer in the right time delay. Special provisions in the implementation guarantee full repeatability of results regardless of the number of computer cores, nodes or threads used in parallel computation. This unique advantage allows to take advantages of the clusters and to apply in a short time optimization techniques. Numerical scattering of results is highly minimized due to the quality of the software.

Here are some of the key advantages of Altair RADIOSS:

  • RADIOSS provides one of the most comprehensive material and rupture libraries in the industry. The material laws and rupture criteria span across definitions for concrete, foam, rubber, steel, composites, biomaterials, and more. The coupling with MDS (Multiscale Design Systems) opens the door to précised and advanced behaviors.

  • RADIOSS is tightly integrated with OptiStruct and HyperStudy. Design optimization and robustness studies can be performed easily to improve design performance.

  • RADIOSS support is very responsive in reacting to user input. A rigorous quality assurance regime makes it possible to implement new features quickly and without regression in quality.

  • PBS Professional is a powerful workload management software. RADIOSS jobs can be efficiently managed and monitored on sever infrastructures to minimize job turn-around-time.

Capabilities

Les domaines d'application de RADIOSS comprennent la sécurité en cas de collision, les essais de chute, l'impact hydrodynamique et le souffle, l'interaction structurale du fluide balistique terminal, la mise en forme et la cartographie des composites.

Un ensemble complet d'éléments, de connecteurs et de conditions aux limites est disponible. Les contacts sont gérés par des algorithmes différents pour garantir la précision et la robustesse en supposant toutes les conditions de contact et certaines conditions d'assemblage. Les lois des matériaux incluant les composites, le béton et les sols, les modèles de rupture (Johnson-Cook, Extended Mohr-Coulomb ....) sont fournis dans les bibliothèques RADIOSS. Tout critère de rupture peut être utilisé avec n'importe quelles lois matérielles. Ces combinaisons apportent plus de 300 matériaux. La modélisation et la simulation avancées des composites dominent l'industrie.

Les formulations d'éléments innovants fournissent des solutions précises, rapides et robustes. Des dizaines de types de conditions limitées sont pris en charge à la fois pour les cas de charge simples et avancés et pour les configurations de contraintes.

Solution types include:

  • Nonlinear explicit dynamic structural analysis

  • Nonlinear implicit structural analysis

  • Explicit Computational Fluid Dynamics (CFD)

  • Euler, Lagrange and Arbitrary Euler-Lagrangian (ALE) formulations

  • Smoothed-Particle Hydrodynamics (SPH)

  • Finite Volume Method (FVM) based airbag simulation. Unique solution for accurate airbag deployment. Pure CFD solution with full coupling with structures.

  • XFEM for crack propagation in multi-layer shells. High interest in pedestrian impact for windshield rupture prediction (Energy absorption) as well screen behavior under impacts for electronic industry, wash machine cover deck behavior under impacts, …

  • Multi-Domain to manage models with fine meshed components needed to “zoom” for rupture prediction. This feature is fully compatible with FSI (Fluid Structure Analysis)

  • Advanced Mass Scaling for quasi-static problems, drop and impact tests, … to increase the time step and by the way reduce the elapse time significantly without degradation of the accuracy.

  • Sub-Modeling for local design of components or sub-structures.

Sécurité des occupants

Pour la sécurité des occupants des véhicules, la simulation RADIOSS a accès à une vaste bibliothèque de mannequins, de barrières et d'impacteur. RADIOSS fournit l’ensemble d'outils le plus complet de l'industrie grâce à des partenariats avec Humanetics et CellBond. Un couplage avec Madymo (TASS) est également possible. En outre, l'environnement de modélisation HyperCrash et HyperMesh offre une prise en charge exceptionnelle pour les simulations d'accident et de sécurité automobiles.
