RADIOSS is a leading structural analysis solver for highly non-linear problems under dynamic loadings. It is highly differentiated for scalability, quality and robustness, and consists of features for multi-physics simulation and advanced materials such as composites. Computation performance has been improved such that 16300+ cores could be used to simulate a 10 million element full vehicle model.

RADIOSS is used across all industries worldwide to improve the crashworthiness, safety, and manufacturability of structural designs. For over 30 years, RADIOSS has established itself as a leader and an industry standard for automotive crash and impact analysis.

Crash and Safety

Major improvements for airbags, in particular Starter capability to generate automatic FVM mesh for folded complex airbags, like multi-chambered ones. Pre-simulation for airbag folding is becoming a standard, but having the folded bag respecting its package constraints requires additional morphing operations that are now implemented inside the solver.

Composites is another domain of major improvements. Ply based input, equivalent to OptiStruct input, is not only more intuitive, but allows seamless combined crash/impact and strength simulations, or multi-objective optimization. In this version, draping information can be directly mapped on composite plies. Each ply can be defined with several integration points through the thickness. The ply-XFEM formulation enhances the delamination prediction capabilities. Stability for the visco-elastic materials has been improved and a new hyper-elastic behavior based on Arruda-Boyce formulation has been added. The coupling with MDS (Multiscale Design Systems) opens the door for material law identification as well design to answer specific dedicated behaviors.

Globally material laws and rupture criteria are fundamental issues for all the industries in the virtual testing approaches. Except composite this version brings an advanced porous foam material law, a new law for high strength steel with strain rate and temperature dependencies developed by MIT to provide an accurate prediction of the local strain fields with a consistent damage indicator.


Extended thermal capabilities represent certainly a big step forward for hot-forming simulation capabilities as well as general applications. Thermal expansion and heat transfer capabilities have been generalized to all materials and element types (solids and shells). New anisotropic material based on Barlat YLD2000 criterion can be used especially for aluminum alloys.

Controlling manufacturing process is sometimes crucial for the performance of a component. Damage evaluation, together with thinning and residual stress and strain is critical for an accurate description of the initial state of a component that after being formed, should undergo a set of tests. Damage initiation is now extended to shells. Damage can also be output into animation files, and might be helpful for failure risk prediction.

Blast Simulation

Thru the Euler and ALE capabilities RADIOSS is brightly used for fluid structure interactions. Improvements have been brought in the multi material regarding the compatibility with the far field boundary conditions. A significant added value lies on the compatibility of the Tetra4 elements with ALE.
