OptiStruct for Linear Analysis

Optimization-enabled Structural Analysis

Building on more than 25 years of innovation, OptiStruct is a proven, modern structural solver with comprehensive, accurate, and scalable solutions for linear and nonlinear analyses across statics and dynamics, vibrations, acoustics, fatigue, heat transfer, and multiphysics disciplines. It is used globally at industry-leading companies to drive design with optimization and validate structural performance.

Commercially introduced in 1994, OptiStruct is a first-to-market simulation technology that seamlessly integrates structural optimization and analysis. OptiStruct solves both linear and nonlinear problems using an enhanced proprietary version of NASTRAN and a modern proprietary nonlinear formulation developed and maintained by Altair.

For the past two decades, OptiStruct topology optimization has driven the lightweight and structurally efficient designs of products you see and use every day. OptiStruct offers many other structural optimization methods and a broad range of essential manufacturing constraints for traditional processes, composites, and additive manufacturing.
