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
