Altair introduces an update to Inspire, its popular software for simulation-driven design. This update includes the addition of SimSolid, Altair’s powerful software for structural analysis of complex assemblies.  

Altair says this update to Inspire is intuitive to learn and runs on standard laptops and workstations already used by designers and engineers; an upgrade to top-of-the-line graphics processing units is not required. 

Simulation is traditionally done at the end of the design cycle, and is used to test one specific design. By moving simulation upfront into design, multiple possible design solutions can be tested, with the best moving forward.

SimSolid’s capabilities to provide fast, accurate structural analysis have been independently validated by NAFEMS. SimSolid joins two other mature simulation tools: OptiStruct for topology optimization using generative design; and MotionSolve, for multibody dynamic motion simulation including loads extraction. 

Design changes can be made directly on models inside Inspire, without reverting to the original CAD system. Interactive modifications such as geometry edits, dimensional changes and part replacements can be immediately reanalyzed inside Inspire.

Several other Altair technologies are included in Inspire, including dynamic motion, design for additive manufacturing, structural analysis, assembly configuration and manufacturing simulation.  

The use of simulation is no longer about specific roles in the organization, says Altair Chief Technology Officer James Dagg, but has become about “when and where it features in the process. Instead of employing it purely for validation at the end of the cycle, Inspire enables users to test more alternatives at the earliest opportunity.” 

The 2020 update to Altair Inspire is now available directly from Altair

A set of videos introducing new features is available here. 

SimSolid remains available to users as a stand-alone solution.
