Simulation-driven Design

The widespread adoption of Altair® SimSolid® has enabled customers to accurately test more ideas during each design iteration. Altair® Inspire™ was the first tool to democratize topology optimization. Inspire now embeds the speed and accuracy of SimSolid to support faster, easier design exploration and product creation, for allowing design engineers, product designers, and architects to create and investigate structurally efficient concepts for complex assemblies.

Structural Optimization

Altair® OptiStruct® is the original generative design tool. While the rest of the industry is still discovering how topology optimization delivers research projects, for the past two decades OptiStruct has driven the innovative, lightweight, and structurally efficient designs of the products you see and use every day. OptiStruct also supports many other structural optimization methods, multi-disciplinary optimization, and provides a broad range of constraints, including traditional processes and additive manufacturing.

Modeling and Visualization

Altair® HyperWorks® has introduced the next generation of market-leading Altair® HyperMesh®, Altair® HyperGraph®, and Altair® HyperView® tools combined with the math, scripting, and data analysis of Altair® Compose®. The new HyperWorks® experience was created to enable your team to move from physics to physics, domain to domain, and even create reports without leaving your model. Altair® SimLab® provides simplified, automated multiphysics workflows with CAD associativity.

Composite Materials

OptiStruct is widely used at the world’s most innovative companies to design and optimize of laminate composites. It delivers optimal ply shapes, the optimal number of plies, and the optimal stacking sequence, while observing manufacturing constraints. Altair® Multiscale Designer® provides accurate and efficient simulation of materials and parts manufactured with continuous and chopped fibers, honeycomb cores, lattice structures, and more.

Linear and Nonlinear Analysis

In addition to optimization, OptiStruct is a fast, industry proven, structural analysis solver for linear and nonlinear problems under static and dynamic loadings. It provides efficient solutions for contacts, heat transfer, bolt and gasket modeling, and hyperelastic materials. OptiStruct is used by thousands of companies worldwide to analyze and optimize structures for strength, durability, and stiffness characteristics. Altair® MotionSolve® is used to determine loading conditions.

Discrete Element Modeling

Altair® EDEM™ is the market-leading software for bulk material simulation. Powered by state-of-the-art discrete element modeling (DEM) technology, EDEM quickly and accurately simulates and analyzes the behavior of bulk materials such as coal, mined ores, soils, fibers, grains, tablets, and powders. EDEM simulation provides engineers with crucial insight into how those materials will interact with their equipment during a range of operation and process conditions.

Crash and Impact

Understanding the safety implications of design decisions is essential across many industries. Altair provides the tools required to bring certainty to engineering simulations including those requiring multiphysics simulation, advanced materials, accurate dummy positioning, and airbag folding. Altair provides detailed modeling and assembly workflows in HyperWorks for scalable and robust analysis using Altair® Radioss® with the highly detailed Humanetics Dummies.

Noise and Vibration

The advanced noise, vibration, and harshness (NVH) analysis in OptiStruct includes one-step transfer path analysis (TPA), powerflow analysis, model reduction techniques (CMS and CDS super elements), design sensitivities, and an equivalent radiated power (ERP) design criterion. In addition, automated multi-level sub-structuring Eigen solver (AMSES) rapidly calculates thousands of modes with millions of degrees of freedom. Perceived quality is further addressed by Altair® Squeak and Rattle Director™.


Durability is an important feature of a product to ensure customer loyalty. Building upon the solver capabilities of OptiStruct, Altair® HyperLife® provides a comprehensive and easy-to-use durability analysis workflow that directly interfaces with major finite element analysis result files. With an embedded material database, HyperLife offers solutions for fatigue life predictions under static and transient loading across a wide range of industrial applications.

Altair Partner Alliance (APA) Solutions for Structures

The APA has established long-term partnerships with some of the leading structural solver software providers.

  • For faster and more accurate analysis of marine vessel and floating structures, MAESTRO by MAESTRO Marine has been fielded as a commercial product for more than 30 years.
  • For composite analysis, Cetim's QSD® features a "design to manufacturing" approach to optimize composite material parts.
  • An important area of structural analysis is NVH, for which the APA features several partner technologies, including AlphaCell by Matelys.
  • For modeling and visualization designed to maximize and accelerate your 3D data, Elysium's CADdoctor solution that reduces time-costing errors and project delays to take the uncertainty out of your 3D data.

These tools and more available are available through your Altair Units license.
