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 Units

You do not buy a user license for Altair Inspire Structures, but you can open the software if you have the right amount of Altair Units. Altair Units can be leased per year and the great thing is that with the right amount of Units you can also open other Altair Inspire titles. This means that you do not need to have a separate user licenses for all software titles, but you buy a number of Units that suits your wishes and needs in terms of software functionality and use.

The Altair Units can be freely distributed within your organization. This allows you to give everyone access to the software you want. This makes Altair Units the most flexible software licensing model available!


Altair Inspire History

New in Inspire 2019.4

Inspire - General

  • Toolbelts
    Inspire now has four toolbelts for quick access to tools for geometry, structures, motion and PolyNURBS. All toolbelts are fully customizable.



  • Shortcuts for Quick Analysis and Force Explorer
    You can now run the function keys to run a structural analysis (F8) or motion analysis (F9) or open the Force Explorer (F10).



  • Download Offline Help
    You can now download and install an offline help package from within the product.


Inspire - Structures

  • SimSolid Analysis
    You can now use SimSolid as your solver when running a structural analysis in Inspire. This gives you the ability to edit geometry as well as yielding significantly faster results when running an analysis in Inspire.



  • Cylindrical Coordinate Systems
    You can now create cylindrical coordinate systems from the Systems tool microdialog.
  • Displacement Component Results in Local Systems
    Displacement components can now be reviewed in local systems using the Animation toolbar.
  • Pressure Mapping
    It is now possible to apply a non-uniform distributed pressure using an option in the Pressure tool’s microdialog.




Inspire - Motion

  • Plot Manager for Motion
    Manually browse and plot motion results data, create cross plots (i.e.,data vs. data), define pages in different layouts, and save the plots you've defined as a template for reuse.



  • Analytical Motion Contacts for Box Primitives
    If motion contact sets contain parts that are detected as box primitives, the solution between the box and other analytical shapes (sphere, cylinder, and frustum) will now be analytical rather than mesh-based. Using geometric primitives in these cases generally improves the efficiency of the solution.
  • Force Computation Option for Motion Contacts
    Motion contacts now have a Force Computed At option available from the guide bar options menu, microdialog, table, and property editor. The new Nodes option can be used to obtain more accurate contact normals for mesh-based contacts in certain applications, such as a sliding contact between a flat region on one part and a curved region on another.
  • Plots of Jerk and Angular Jerk
    Jerk and Angular Jerkplot components are now available in the plot context menu for actuator and motor, respectively. They can be used to measure the derivative of acceleration during transient motion analysis.



  • Export Data at Output Steps Only
    When exporting CSV files from a model that includes motion contacts, there is now an additional option in the context menu that allows you to export only the output steps.
  • Write a.h3d Output File from MotionSolve
    You now have the option to select Generate Animation File in the Advanced section of the Run Motion Analysis window. When enabled, MotionSolve will write a run.h3d file to the run history folder at the end of a successful motion analysis. This file can be used to playback the animation in HyperWorks(via HyperView) or using the stand-alone HyperView Player.




Inspire - Print3D

  • Min Undercut tool
    This new tool orients the part to minimize the supports needed for 3D printing. It analyzes possible orientations and selects the one that minimizes the total area of the undercut surfaces.
