For more than 30 years, Radioss has been a successful commercial software product utilized around the globe to help major automotive OEMs develop 5-star rated crash performance vehicles, aerospace companies simulate “hard” landings and bird strikes, and consumer electronics manufacturers analyze impact events, like cell phone drops.

“Radioss is a first-rate technology for solving transient dynamic events with outstanding robustness and accuracy. It is a tool that’s massively parallel and readily scalable, and gives numerically consistent and reliable results,” said James R. Scapa, founder and chief executive officer, Altair. “Staying true to Altair’s open architecture philosophy, OpenRadioss allows everyone to contribute, drive their own innovations, develop and share their own models, and experiment by getting inside the code. This makes OpenRadioss an agile tool that always stays on the cutting edge, regardless of industry.”

With OpenRadioss, Altair envisions faster advances in technology that will speed up research focused on solving today’s most complex challenges. Additionally, the newly established OpenRadioss Community will benefit from the industry-proven comprehensive code base, modern software architecture with the most advanced hybrid (SMP+MPI) parallel structure, and robust numerical methods based on explicit time integration schemes.

This highly engaged international community from the world’s best universities, most innovative startups, and the industry’s biggest technology providers and top researchers will extend OpenRadioss’s capabilities, disseminating the code to new users, industries, and organizations. This revolutionary way to collaborate bridges the gap between state-of-the-art research and industry needs and leverages Altair’s expertise to maintain this production-grade open software platform to develop advanced technologies, share best practices, and enrich model libraries around OpenRadioss.

“OpenRadioss is a game changer for academia, research institutions, and industry alike, and gives the users the power to modify mature codes for their own use – without having to start from scratch – and lets users collaborate to accelerate the pace of innovation,” said Elham Sahraei, associate professor of mechanical engineering, Temple University.

Additionally, OpenRadioss can read and run models written with LS-DYNA* syntax, enabling the community to contribute and harmonize model building. As such, OpenRadioss is positioned to be the most accessible, powerful, open-source software for accurate simulation of complex multiphysics dynamic events.

Altair Fuels Better Decision Making and Faster Optimization with Latest Release of Integrated Simulation and Analysis Portfolio


Altair (Nasdaq: ALTR), the global leader converging simulation, HPC, and AI, announced significant enhancements to its integrated portfolio of simulation and design tools. This update to Altair’s simulation software suite is focused on accelerating simulation-driven design and unleashing the power of AI by embedding augmented intelligence in the broadest possible range of computer-aided engineering (CAE) tools.

“The latest release of our simulation solutions embodies Altair’s position at the sweet spot converging simulation, HPC, and AI. For engineers, designers, and simulation specialists, this release fosters exploration, innovation, and collaboration,” said James R. Scapa, founder and chief executive officer, Altair.

Enhancing simulation-driven design

Simulation 2021.2 takes simulation-driven design to the next level. Simplified modeling workflows offer even faster design iterations, resulting in optimal, manufacturable designs earlier than ever in the development cycle. Enhancements include:

  • Parametric feature-based modeling and simulation workflow – Altair® Inspire™ makes geometry modeling and editing accessible to all designers and engineers, even if they do not have time or access to traditional computer-aided design (CAD) tools. A robust history-based CAD modeling approach ensures creation and modification of geometry is quick and easy.
  • Ability to perform what-if studies faster and more easily – Altair’s high-end solvers powering Inspire encourage wider collaboration and extend to flexible bodies for motion analysis and even faster integration with Altair® SimSolid®, facilitating rapid analysis of large assemblies.
  • A comprehensive Python-based API – More than 500 documented, running examples enable fast automation and customization of simulation-driven design and manufacturability workflows.

The right model, for the right decision, at the right time

Simulation 2021.2 combines computationally efficient reduced order models and detailed CAE analysis with process automation of labor-intensive tasks. Users can now build mixed fidelity models with the appropriate complexity to help faster decision making. A major development includes Altair® Pulse™a new tool that orchestrates meaningful models from the broad workflows required to simulate complex systems of systems to the focused workflows needed to enable fast, reliable, and repeatable modeling, analysis, and optimization. Across the entire product development lifecycle, Pulse accelerates decision-making, and inspires greater confidence in the process. Key features and capabilities include:

  • A digital thread that drives script consolidation, process commonization, and data traceability for simulation key performance indicators (KPIs) across the enterprise and throughout the product lifecycle.
  • Digitizing best practices to increase team efficiency and analysis consistency, while reducing procedural errors and non-value-added time. More effort can be invested in using simulation to inform performance targets, evaluate attribute trade-offs, and explore what-if scenarios.
  • Boosting efficiency by using multiple scripting languages to eliminate repetitive tasks across applications, even for complex processes.

Bringing augmented intelligence to a broad range of CAE tools

AI-driven design, augmented intelligence, and predictive analytics all contribute to broader collaboration, faster design convergence, and greater product innovation. Machine learning (ML) algorithms in this solution suite are leveraged in three main areas:

  • Augmenting existing products with AI – Beginning with the modeling and visualization products, the latest release of Altair® HyperWorks® includes features like shapeAI, which applies ML to quickly find and classify parts by shape inside geometry files or finite element meshes.
  • Adding AI power to product design – Altair HyperWorks’ Design Explorer enables easy set-up and execution of design of experiments (DOE) and optimization studies and deploys ML models to provide real-time field predictions for any design change.
  • Leveraging field data across the entire product lifecycle – With new tools like signalAI, ML can interpret field data to prevent product failures when the data shows health deterioration and predict the effects of environmental changes in real time.

“Leveraging new capabilities enriched by AI, we are liberating users from tedious and repetitive tasks, and enabling them to run more what-ifs and design iterations,” said Scapa. “By supporting better decision making at the earliest possible opportunity, Altair is once again accelerating and optimizing design and manufacturing outcomes.”

All products are available through Altair Units, which gives customers easy and cost-efficient access to Altair’s entire portfolio of software solutions. For further information on the latest simulation software update, visit or register to attend Future.Industry at
