What is Altair Inspire Structures?

Altair Inspire enables design engineers, product designers, and architects to create and investigate structurally efficient concepts quickly and easily. Traditional structural simulations allow engineers to check if a design will support the required loads. Altair Inspire enhances this process by generating a new material layout within a package space using the loads as an input. The software is easy to learn and works with existing CAD tools to help design structural parts right the first time, reducing costs, development time, material consumption, and product weight.

Altair Inspire - The Future of Simulation-Driven Design
Dynamic Motion with Altair Cast


Easily generate dynamic motion of complex mechanisms and automatically identify contacts, joints, springs, and dampers. Forces obtained from a motion analysis are automatically applied as inputs to structural analysis and optimization or can be used to determine initial requirements for motors and actuators.

PolyNURBS Fit Tool

Automatically optimize the fit of PolyNURBS CAD geometry to generative design results with the new PolyNURBS Fit Tool.

PolyNURBS Fit Tool feature in Altair Cast 2
Lattice structures generation with Altair Cast


Generate optimized lattice and mixed solid–lattice structures, visualize simulation results in 3D, and export lattice designs in a .stl file format for 3D printing.


View and interactively assign loads to load cases and import/export design loads in .csv file format with the new Load Cases Table.


Design for additive manufacturing with overhang shape controls to help reduce overhangs to create more self-supporting structures.
