What is Altair RADIOSS?
RADIOSS’ comprehensive analysis capabilities for linear and non-linear finite element analysis, sheet metal stamping, and multi-body dynamics are accessible via two input formats.
Finite element solutions via Nastran-type Bulk Data Format include:
? Linear static analysis
? Non-linear implicit quasi-static contact analysis
? Linear buckling analysis
? Normal modes analysis
? Frequency response analysis
? Random response analysis
? Linear transient response analysis
? Linear fluid-structure coupled (acoustic) analysis
? Linear steady-state heat transfer analysis coupled with static analysis
? Inertia relief analysis with static, non-linear contact, modal frequency response, and modal transient response analyses
? Component Mode Synthesis (CMS) for the generation of flexible bodies for multi-body dynamics analysis
? Reduced matrix generation
? One-step (inverse) sheet metal stamping analysis
A typical set of finite elements including shell, solid, bar, scalar, and rigid elements as well as loads and materials is available for modeling complex events.
Finite element solutions via RADIOSS Block format include:
? Explicit dynamic analysis
? Non-linear implicit static analysis
? Transient heat transfer and thermo-mechanical coupling
? Explicit Arbitrary Euler-Lagrangian (ALE) formulation
? Explicit Computational Fluid Dynamics (CFD)
? Smooth Particle Hydrodynamics (SPH)
? Incremental sheet metal stamping analysis with mesh adaptivity
? Linear static analysis
? Normal modes analysis
? Linear and non-linear buckling analysis
A typical set of finite elements including shell, solid, bar, and spring elements, rigid bodies as well as loads, a number of materials, contact interfaces are available for modeling complex events.
Multi-body dynamics solution integrated via Nastran-type Bulk Data format for rigid and flexible bodies includes:
? Kinematics analysis
? Dynamics analysis
? Static and quasi-static analysis
? Linearization
