Altair Radioss

What is Altair Radioss?

Altair Radioss is a leading structural analysis solver for highly nonlinear problems under dynamic loads. It is used in all sectors of the world to improve failure resistance, safety and manufacturing capacity of structural projects.

For more than 30 years, Radioss has established itself as an industry leader and standard for automotive strikes, fall and impact analysis, terminal ballistics, explosion and explosion effects, and high-speed impacts. Automotive, aerospace, electronics, defense companies, and R&D centers value the contribution they make to understanding and predicting project behavior in complex environments such as automotive accidents, aircraft crashes, or vehicle explosion. Strong integration with the HyperWorks environment makes Radioss a powerful design tool. Radio models are ready for optimization. Transitions to the OptiStruct and HyperStudy optimization solver are easy.

Benefits

Scalability, quality and repeatability

Advanced multiprocessor versions of Radioss (Hybrid Massively Parallel Processing) have enabled industry-best scalability for large, nonlinear structural simulation. The use of Advanced Mass Scaling and the single precision option accelerate orders of magnitudes while maintaining the same accurate results. You can also get detailed and accurate analysis without decreasing overall time or increasing the total simulation time. Acceleration solutions, such as multi-domain and submodel, are unique solutions to provide the right answer at the right time.

Here are some of the main advantages of Altair radios:

• Radioss provides one of the industry's most comprehensive material and rupture libraries. Material laws and breakage criteria cover definitions of concrete, foam, rubber, steel, composites, biomaterials and more. Coupling with Multiscale Design Systems (MDS) opens the door to advanced and advanced behaviors.
• Radioss is fully integrated with OptiStruct and HyperStudy. Project optimization and robustness studies can be easily performed to improve project performance.
• Radio support is very responsive when reacting to user input. A strict quality assurance regime allows you to implement new features quickly and without quality regression.
• PBS Professional is powerful workload management software. Radio jobs can be efficiently managed and monitored across multiple infrastructures to minimize job execution time.

resources

Radioss' application areas include collision safety, fall testing, explosion impact and hydrodynamics, terminal structural interaction of ballistic fluid, formation and composite mapping.

A complete set of elements, connectors, and contour conditions are available. Contacts are managed by different algorithms to allow accuracy and robustness, assuming all contact conditions and some assembly. Material laws, including compounds, concrete and soils, fault models (Johnson-Cook, Extended Mohr-Coulomb) are provided in Radios through libraries. Any breaking criteria can be used with any of the relevant laws. These combinations bring more than 300 materials. Advanced composite modeling and simulation are leading the industry.

Innovative element formulations provide precision, speed and robust solutions. Dozens of threshold condition types are supported, for simple and advanced load cases and constraint settings.

Solution types include:

• Nonlinear explicit dynamic structural analysis
• Nonlinear implicit structural analysis
• Explicit Computational Fluid Dynamics (CFD)
• Formulations by Euler, Lagrange and Euler-Lagrangiano Arbitrary (ALE)
• Hydrodynamics of smoothed particles (SPH)
• Finite volume method-based airbag simulation (FVM). Unique solution for precise deployment of the airbag. Pure CFD solution with complete coupling with structures.
• XFEM for crack propagation in shells of several layers. High interest in the impact of pedestrians in the prediction of windshield breakage (energy absorption), as well as in the behavior of the screen under impacts for the electronic industry, in the behavior of the washing machine cover under impacts.
• Multiple domains to manage models with fine mesh components required to "zoom in" for break prediction. This feature is fully compatible with Fluid Structure Analysis (FSI)
• Advanced mass scaling for near-static problems, drop and impact tests, to increase the time interval and, by the way, significantly reduce elapsed time without degrading accuracy.
• Submodel for local design of components or substructures.

Occupant safety

For the safety of vehicle occupants, the simulation Radioss has access to a large library of mannequins, barriers and impacts. Radioss provides the industry's most comprehensive toolset through partnerships with Humanetics and CellBond. It is also possible to mat with Madymo (TASS). In addition, the HyperCrash and HyperMesh modeling environment provides excellent support for collision simulation and automotive safety.
