Altair Radioss
Breakthrough solution for crash analysis, destruction and safety calculation
1. What is Altair Radioss?
Altair Radioss is the leading structural analysis solver for non-linear problems under dynamic loads. The solver makes a difference thanks to the scalability, quality, durability, and features for multi-physics simulation and advanced materials such as composites. Radioss is used in many industries around the world to improve the risk of collision, destruction or accounting to the safety and production feasibility of structural designs.
2. Benefits Radioss software brings
2.1. Offers scalability, quality and stability
Radioss's advanced solution (mixed parallel processing) allows the user to have the scalability to simulate large, nonlinear structures. Ensure analysis results without worrying about number of computer cores, number of element nodes, or parallel data processing streams. This helps to minimize the results deviation.
Using Advanced Mass Scaling (AMS) technology and accurate intelligent computation increases simulation speed with model magnitude while keeping accurate results. AMS provides an advanced solution for semi-static problems, with models with small mesh sizes in a certain region of the model. AMS is also an alternative to non-linear simulation due to high convergence in contacts, complex materials or rupture patterns.
2.2. Meets industry safety and crash analysis standards
With more than 30 years of development, Radioss has established a leading industrial safety standard for crash analysis, safety and destruction analysis. The number of passengers continues to increase at an impressive rate with more than 1000 companies worldwide, 40% of customers are in the automotive industry.
Radioss is ranked 5-star by leading automotive and aerospace companies for dealing with the complex problems related to destruction and collision. Radioss has direct access to the finite library of finite element simulation models to perform secure simulations for vehicle users.
Radioss delivers the industry's most comprehensive and effective toolkit through partnerships with leading global safety and destruction testing and model vendors.
2.3. The most comprehensive material library available
Radioss has the most comprehensive material libraries with more than 300 materials. A comprehensive material library synthesis from linear to nonlinear materials provides modeling of the most complex details. Corresponding material rules and destruction criteria include definitions of materials such as concrete, rubber, steel, composite materials, biological materials ... Many destructive criteria can be applied. Any material.
2.4. Advanced multi-environment simulation
