Altair® OptiStruct® is a state of the art finite element solver for linear and non-linear structural problems. It employs implicit integration schemes for static and dynamic problems. Besides mechanical loading, heat transfer coupled with structures is also available.

OptiStruct is designed with optimization at the core. The majority of solution sequences are available for optimization. A wide range of design problems can be solved addressing concept design and design fine tuning. In addition, RADIOSS and MotionSolve have been integrated to address multi-disciplinary optimization involving crash and impact, and multi-body systems, respectively. The optimization capabilities of OptiStruct are innovative and market-leading.

Analysis applications of OptiStruct include Automotive powertrain durability and vibrations, vehicle interior acoustics, vibrations of satellites, durability of heavy duty and off-road vehicles, component stress and vibrations analysis, detailed finite element analysis of airplane structures, random vibrations of ships and buildings, structural behavior of composite wings, buckling behavior, etc.

Optimization applications of OptiStruct include material layout of structures and parts under static loads, sheet metal sizing under static and dynamic loads, improvement of acoustic behavior, design of parts for additive manufacturing, design of composite layups, etc.
