Altair® Radioss® Applications
Radioss has established itself as an industry leader to evaluate and optimize product performance for automotive crash and safety, shock and impact, drop, terminal ballistic, blast and explosion, and high velocity impacts.
For numerous, diverse industries worldwide, Radioss is a versatile and comprehensive high-performance explicit finite element (FE) solver, based on solid- and fluid dynamics.
It is the standard "go-to" tool to accurately predict dynamic, transient-loading effects on structures and products to improve safety, survivability, and design more robust products.
Learn More About Radioss
Large Nonlinear Motion and Materials
Radioss helps engineers consider the overall system behavior where large nonlinear motion and nonlinear material behavior, with or without rupture, are the dominating characteristics under dynamic or quasi-static loadings with huge geometrical and/or material deformations, like those seen in side crash tests for battery-powered electric vehicles (BEV), sporting goods under extreme loadings, biomechanics under injury conditions, defense and land security under explosions
Crashworthiness
Irrespective of the vehicle, for more than 30 years Radioss has been accurately predicting crash response to help vehicle designers meet safety standards.
Safety
Ensuring the safety of vehicle occupants, Radioss delivers fast accurate results for airbag deployment and barrier effects with human and anthropomorphic test device (ATD) models.

Birdstrike
With more than 17,000 incidents in the U.S. in 2019, bird strike remains a significant threat to the airworthiness of aircraft windshields, structures, instrumentation, and engines. Radioss’ validated bird models and multidomain simulation reliably identify and help reduce bird strike damage.
Ditching
By applying the Radioss multidomain on arbitrary Lagrangian-Eulerian (ALE) or Smoothed-particle hydrodynamics (SPH) models, users obtain a significantly faster simulation of full ditching scenarios comprising approach and structural response when hitting the water and flotation.
Ships, Offshore, and Energy
As part of Altair’s full shipbuilding analysis solution, Radioss enables impact scenarios between ships and docks. Its fluid structure interactions (FSI) capabilities give efficient simulation of slamming and wave effects on shipping, tethers and risers on offshore platforms, underwater pipe laying and green energy production structures.
Blast and Bullet Protection
Whether on land, at sea or in the air, effective protection from the effects of accidental or threats from explosive devices or munitions are accurately simulated with Radioss, including terminal ballistics studies.

Outstanding Scalability at NIAR - Advanced crash analysis solution proves twice as fast as leading competitor
To support its goal of accelerating the development cycle, early in 2020 NIAR commissioned a study to assess the scalability of Altair Radioss™, Altair’s structural analysis solver for highly non-linear problems under dynamic loadings. Regular support from an Altair engineer ensured swift familiarization with Radioss. The study was performed on Oracle Cloud Infrastructure (OCI). OCI with its bare metal HPC shapes that use low latency RDMA interconnect provided highly scalable infrastructure-as-a-service (IAAS) for Radioss.
