RADIOSS selected as a strategic tool

Long time experience

Confidence in Altair as viable partner

OptiStruct selected as a strategic tool for A350

Based on successful employment for A380

Will be used by all Airbus development centers and suppliers

CustomerSuccesses

Solvers

Use OptiStruct/Analysis

Convenient use and high value of HyperWorks

Freeing licenses of other software for non-linear analysis

"We compared OptiStruct and MSC/NASTRAN

results and found good correlation for linear static,

normal modes and frequency response analysis.

Solver ReBrandingHyperWorks 9.0

OptiStruct has become the de facto standard for structuraloptimization in various industries

E.g. used in the development of A380, Boeing 787 & JSF

RADIOSS is recognized in the industry as high performance finiteelement solver for highly non-linear transient events

OptiStruct will be Altairs brand for Design and Optimization

RADIOSS will be Altairs brand for all Finite Element solvers

MotionSolve will remain Altairs brand for Multi-body Dynamicssolver
