The most user friendly topology optimisation software! Design engineers and architects use Altair Inspire™ to generate and explore structurally efficient concepts in the earliest phases of the design process. This will lead to reduced costs, development time, material consumption, and product weight.



© Altair Engineering, Inc.



Altair Inspire™ is fast. You will have an optimised, weight-efficient shape within minutes! Inspire generates the ideal shape for a design given the package space, material properties and the loading requirements.


Altair Inspire™ uses the trusted Siemens Parasolid® 3D kernel. Combining it with Altair's OptiStruct optimisation solver as its engine, Inspire will generate powerful, lightweight product concepts.

Costs Saving

Leveraging simulation-driven design with Altair Inspire™ early and often in the design process enables costs savings by reducing material usage, re-design iterations, and overall design time.

Altair University

Altair University: Het online platform voor Altair Training & Academic Programs

The home for Altair Training & Academic Programs

Altair facilitates a source of instructive training programs, tutorials and other learning materials with Altair University. Software users from the Altair platform, but also students can go here for learning purposes or amplify their knowledge of the software.

For example, as a user on this platform you will find the Training Program with an overview of (virtual) training, tutorials, ebooks and learning materials that you can follow at your own pace. Students can go to the Academic Program for free software licenses, academic learning tools, tutorials, ebooks and even internships!

You can also use the Altair Support Forum at Altair University where you can go for specific user questions.

Simulation-Driven Design in the Cloud

For 10 solidThinking Units extra you get access to the Altair 365 Cloud Platform. With Altair 365 you will be able to:

  • Have a 16 core Altair processor compute up to 4 parallel sessions in the Cloud;
  • Run the software online in a browser as well as on your desktop.



Altair Inspire™ is equipped with the following functionalities to offer you the highest level of topology optimization.


System Requirements



  • Windows 7 to 10 - 64 Bit

System requirements:

  • Intel Core2Duo processor or higher
  • 4 GB RAM
  • Video card 256+ MB 100% OpenGL
  • 3-button mouse with scroll function

Video card

* If you are looking for a new system or upgrade, please pay extra attention to the video card. We do recommend video cards with a nVidia Quadro or GTX chip. These cards support OpenGL very well and have qualitative drivers.


At this moment, there's no macOS version of Altair Inspire™ available. People who are interested in Altair Inspire™, can try Inspire Unlimited in the cloud (beta).








At this moment, there's no Linux version of Altair Inspire™ available. People who are interested in Altair Inspire™, can try Inspire Unlimited in the cloud (beta).







solidThinking Units

Access to all products within the Altair Inspire Platform!

solidThinking Units is a revolutionary license model replacing the traditional way of licensing software.

Normally you’d choose a software title for which you’d purchase a license. With solidThinking Units, you choose a number Units to start any product you want for which you have enough Units.

You lease solidThinking Units per year or per month.

solidThinking Units can be freely distributed within your organization. This way, you can grant access to the software to anyone in your organization. In case you have unused Units left, you can use these to perform calculations in the Cloud! This makes solidThinking Units the most flexible software licensing model that exists today.


Altair Inspire History

New in Inspire 2018
  • Lattice Optimization
    Inspire 2018 is able to fill (parts of) the structure with small beams that can vary in length and thickness to create an even lighter optimized shape.Benefits:
    • Use for implants in medical applications so that tissue and bones can grow through
    • Use for heat sink design where air can flow easily
    • Use for infills of hollow products instead of a random hatching pattern
  • Better 3D printing support
    Inspire 2018 has a number of functions to make sure created shapes 3D print well:
    • Overhang protection at a given angle
    • Lattice structure to be exported in STL
  • PolyNURBS Improvements
    It is now easier than ever to wrap a generated shape with a supersmooth PolyNURBS geometry:
    • Autofit a wrapped shape to match the optimized shape as much as possible
    • Create sharp edges
    • Create flat surfaces
    • Fillet PolyNURBS geometry to underlying geometry
  • Spreadsheet Linking
    It is now possible to link several Load Cases into a spreadsheet to quickly explore multiple strength cases.
  • Motion
    A number of improvements have been implemented in the Inspire Motion Module:
    • You can now add friction to joints
    • You can you alter Motor characteristics interactively using the new Profile Editor
    • You can now move points and geometry directly on the screen interactively
  • New Bonding options
    When creating Mid Surface Geometry for Sheet Metal Analysis you can now add Spot Welds. It is also possible to specify the weld material.
  • No Mac OS X version
    No Mac version will be developed after version 2017.1. Mac users may migrate to the Inspire Unlimited version online at http://unlimited.solidthinking.com/inspire/.
