Altair **RADIOSS** is a multidisciplinary finite element solver developed by Altair Engineering. It can solve both linear and non-linear problems. It is a finite element solver using implicit and explicit integration schemes for the solution of engineering problems, from linear statics and linear dynamics to nonlinear transient dynamics and mechanical systems. This multidisciplinary solver enables designers to maximize performance related to durability, NVH, crash, safety, manufacturability, and fluid-structure interaction, in order to bring products to market faster.

RADIOSS’ analysis capabilities for linear and non-linear finite element analysis, sheet metal stamping, and multi-body dynamics are accessible via two input formats.

Linear static analysis
Non-linear explicit dynamic analysis
Non-linear implicit quasi-static analysis
Normal modes analysis for real and complex eigenvalues
Linear buckling analysis
Frequency response analysis
Random response analysis
Linear transient response analysis
Linear coupled fluid-structure (acoustic) analysis
Linear steady-state heat transfer analysis coupled with static analysis
Explicit Arbitrary Eulerian-Lagrangian (ALE) formulation
Explicit Computational Fluid Dynamics (CFD)
Smoothed-particle hydrodynamics (SPH)
One-step (inverse) and incremental sheet metal stamping analysis
Constraints like joints, gears, couplers, user-defined constraints, and high-pair joints can be defined. High pair joints include point-to-curve, point-to-surface, curve-to-curve, curve-to-surface, and surface-to-surface constraints. They can connect rigid bodies, flexible bodies, or rigid and flexible bodies. For this multi-body dynamics solution, the power of Altair MotionSolve has been integrated with RADIOSS.
