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.

Safety System Simulation with MADYMO-Radioss
The Webinar will outline how engineers can combine the best of both worlds in a single co-simulation environment and gain considerable time saving in vehicle developments. The Radioss-MADYMO coupling solution enables engineers to use the same MADYMO dummy and restraint models in occupant safety analysis as well as in the RADIOSS structural analysis. This removes the need to create intermediate FE models of the restraint system, which reduces development time and provides higher confidence in simulation results.
Assuring Scalability: Altair Radioss™ Delivers Robust Results Quickly for Crash-Safe Vehicle Designs
In the race to deliver safe new vehicles, efficient and accurate simulation of structural performance under different crash scenarios is a key alternative costly physical testing. With growing model complexity, the demand for CPUs is increasing. To assure a fast job turnaround time, HPC and solver scalability is critical. This article shows that by working together with market-leading hardware developers to keep one step ahead of customer needs, Altair Radioss™ offers fast, efficient structural analysis irrespective of the hardware the solver is running on: scalability is proven and assured.
Digital Transformation in Oral Healthcare - iLittleMiracle Uses Digital Twin Powered by Altair® Radioss® for Oral Healthcare Analysis
iLittleMiracle (iLM) was founded in 2011 and is headquartered in Beijing, China. The company is a leading brand that focuses on the early correction of malocclusion and deformity in children between 5 and 12 years old. Through digital innovation, iLM is committed to promoting the continuous innovation and popularization of medical technology for full-cycle facial development management in children.
Orthodontic treatment is one of the biggest categories in dentistry, comprising the highest number of cases each year. As cases increase, it’s crucial to address the shortcomings of traditional, non-digitized methodologies. iLM employs Altair Radioss, Altair RapidMiner, and Altair Monarch, which allow orthodontists to make predictions in a faster, easier way thanks to the tools’ unparalleled simulation and visualization capabilities.
