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.

OptiStruct has been built on over 25-years of innovation, and is used globally at industry-leading companies to drive design with optimization and validate structural performance.

Commercially introduced in 1994, Altair 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.

While some are still discovering how topology optimization and generative design can shape research projects, OptiStruct has been integral to the design of mass-produced parts. OptiStruct offers many other structural optimization methods and a broad range of essential manufacturing constraints for traditional processes, composites, and additive manufacturing.
