Altair Radioss.
A high-fidelity explicit dynamics solver for simulating highly nonlinear events
Highly nonlinear event simulation
This high-fidelity explicit dynamics solver accurately simulates crash, impact, blast, and other highly nonlinear events.
Trusted across automotive, defense, aerospace, and manufacturing, Altair Radioss delivers proven accuracy for structural safety and material failure modeling, scaling efficiently across modern computing architectures.
Industry-proven explicit dynamics performance
Specialized tool for transient events requiring precise handling of contact, large deformation, and material failure.
Altair Radioss is extensively validated in crashworthiness, ballistic, and blast applications, supporting safety certification and regulatory compliance.
Comprehensive contact and material modeling
Benefit from the solver’s robust contact algorithms (node-to-surface, surface-to-surface, and self-contact) and advanced material laws for metals, composites, polymers, foams, and brittle media.
Altair Radioss supports progressive damage, element erosion, and realistic failure progression.
Fluid–structure and multiphysics coupling
Particularly suitable for multi-physics safety and defense simulations, Altair Radioss handles Arbitrary Lagrangian–Eulerian (ALE) and Smoothed Particle Hydrodynamics (SPH) formulations for modeling fluid–structure interactions such as airbag deployment, sloshing, explosions, and impacts.
HPC scalability and parallel efficiency
Altair Radioss achieves exceptional scalability through domain decomposition and parallelization.
Reduce simulation turnaround times from days to hours with the ability to efficiently run full-vehicle models with millions of elements across CPUs, GPUs, and distributed clusters.
Integration with the Altair Ecosystem and PhysicsAI
Benefit from a workflow that merges traditional accuracy with AI-powered speed for next-generation simulation strategies.
Altair Radioss models can be prepared and post-processed in HyperMesh, SimLab, and HyperView, and the solver data can train Altair PhysicsAI models for predictive analysis.
