Radioss Overview

Radioss is a leading explicit finite element solver for crash and impact simulation.

Altair Radioss is an industry-leading explicit solver for highly nonlinear scenarios, offering a powerful commercial package within Altair’s software ecosystem, and OpenRadioss™, a continuously developed open-source version for research and development (R&D). Trusted worldwide, Radioss delivers accurate multi-physics simulations of complex systems responding to dynamic loadings, such as impact, crash, ballistics, and blast, as well as manufacturing and assembly processes, product misuse, and accidental component failure scenarios. Its unique compatibility enables users to run input decks directly from trusted industry solvers – no conversions needed. With unmatched scalability and AI integration, Radioss redefines explicit simulation, empowering engineers to push limits like never before.

Applications of Radioss include:
  • Crash & Safety in Automotive: Failure risk assessment, Airbag Folding & Deployment, Safety barriers models, Safety dummy models
  • Crash & Safety in Aeronautics: Bird strike, Composite Modeling Failure risk assessment, Seat & Safety
  • Ultra High-Velocity Impact on Space applications
  • Drop and Impact Analysis: Cellphone, Bottle, Motor Helmet
