【 Advantages 】
High scalability, high quality, and high robustness
.......In industrial applications, its advanced Hybrid Massively Parallel Processing technology provides outstanding scalability for solving large deformation and highly nonlinear structural analysis problems. When using the Radioss solver, the influence of the number of CPU cores, nodes, and threads on the simulation can be minimized, ensuring highly repeatable simulation results while significantly reducing computation time.
Industry standard for occupant safety and impact analysis
.......The Radioss solver has been under continuous development for more than 30 years and has established itself as a market leader and an industry standard for crash, safety, and structural analysis. Today, more than 1,000 companies worldwide use the Radioss solver, and the number of customers is still growing every year, with 40% of them coming from the automotive and related industries. Radioss is recognized as a five-star crash simulation code. In the automotive and aerospace fields, it is widely used to analyze and predict the behavior of different design features in complex crash and impact environments. Radioss provides a rich library of finite element dummy models, barriers, impactors, and human biomechanical models. Through collaboration with partners, it offers the most complete, high-quality tool models. In addition, the Altair HyperCrash pre-processor provides a dedicated modeling environment for automotive crash and safety simulations.
Comprehensive material constitutive and failure model library
.......The Radioss solver includes one of the most comprehensive material constitutive and failure model libraries (with more than 300 combinations), enabling simulation of metals, alloys, composites (PLY-based and compatible with OS format), foams, rubber, concrete, biological materials, and many more material behaviors, together with multiple failure models that can be combined as needed. The explicit extended finite element method can be applied to multi-layer structures to better simulate crack growth. In addition to Lagrangian formulations, Radioss also provides advanced multi-physics simulation technologies such as Eulerian formulations, Arbitrary Lagrangian–Eulerian (ALE), Smoothed Particle Hydrodynamics (SPH), and the finite volume method. Based on these fluid algorithms, the Radioss solver can perform fluid–structure interaction and multi-material flow simulations. The finite volume airbag algorithm realistically represents gas flow inside the airbag. With its accurate results and fast solution performance, it is widely used for airbag simulations in full vehicle models as well as sealed component simulations. Benefiting from the HyperWorks solution platform, the Radioss solver also supports nonlinear optimization. Combined with Altair OptiStruct and HyperStudy, Radioss has become a key component in advanced optimization-driven design and robustness analysis workflows.
