Altair RADIOSS RADIOSS 12.0 New Feature Highlights What's New in RADIOSS 12.0 Contact Tensile and shear Ruptures can be defined in the kinematic tied interface Tied interface with penalty formulation resolves incompatible kinematic conditions Activation and de-activation of contacts are available based on a minimum time step value Rayleigh damping can be added to the contacts – interest to reduce numerical dispersion. Concave as well as convex shapes could be defined in the “curvature” interfaces. Elements Crushable beams can be used for simplified crash models New predefined sections for integrated beams Deformation speed dependent damping for beam type springs Extended “physical” Hourglass control to hyper-visco-elastic materials in HEPH elements New kinematics joints Material Laws & Rupture Criteria, EOS Prager-Ziegler kinematic hardening in elasto-plastic material law Fabric porosity can be defined in the fabric material for airbags Johnson-Holmquist EOS for ceramics Thermal radiation has been added for hot forming Yoshida-Uemori material law for stamping – improvement of the springback analysis New rupture criteria for spotwelds, welding lines, glue and laminate plane composites General features Transformations on sub-models will simplify the input set up. Any fields of RADIOSS options could be defined using a parameter set. New pressure loading function for hydrostatic, air flow, … conditions Centrifugal initial conditions based on implicit resolution. Improvements Improvements of the Advanced Mass Scaling (AMS) - compatibility with mesh adaptability – new time step control for contacts. Improvement of the Single Precision version interesting for crash, drop, … analysis Speed up improvements thru starter and SPH inlet/outlet parallelization - (10M+ SPH models are running) GPU porting of RADIOSS implicit iterative solver
