Inspire

Inspire accelerates the conceptual development process by generating structurally optimal parts and assemblies. It is an intuitive and easy to use tool, compatible with all current CAD tools.

Inspire, the industry's most powerful and easy-to-use generative design/topology optimization and rapid simulation solution for design engineers empowers its users by creating and investigating structurally efficient concepts quickly and easily. This can lead to reduced costs, development time, material consumption, and product weight.

The software is easy to learn and works with existing CAD tools to help design structural parts right the first time. Applied at the very beginning of clean-sheet design programs and for design exploration of current production parts, Inspire simulation-driven design software allows designers and engineers to:

  • Rapidly assemble and simulate dynamic mechanical systems to automatically resolve loads on system components for optimization and analysis
  • Generate weight-efficient design proposals unique to specified conventional or additive manufacturing processes with Altair's industry-leading topology optimization technology
  • Simulate the performance of competing design concepts for static loads, normal modes and buckling
  • Directly export Inspire CAD geometry to 3D printers to produce high-performance, quality parts
“Inspire provides a tool that can quickly suggest ideal part geometries, giving an opportunity to reduce development cycle time and enhancing the knowledge of the engineer regarding structural requirements of the component.

Benefits

Design Faster

Generate concepts which meet structural performance requirements at the beginning of the design cycle. This results in significant time savings over the traditional approach of design, validate, redesign to meet structural requirements.

Design Smarter

Inspire makes it easy to perform “what-if” scenarios where package space, connections, load conditions, and shape controls can be modified. Reviewing the resulting concepts often reveals valuable insights. Design Lighter Inspire makes efficient use of material, only placing it where required to satisfy structural performance requirements. Reduced design weight leads to material cost savings, performance improvements, and reduced shipping costs.

 

Capabilities

Geometry Creation and Simplification

Create, modify, and de-feature solid models using Inspire’s modeling tools:

  • Sketch Tools – Build or modify parts by sketching lines, rectangles, circles, and arcs.

Geometric constraints such as mirroring, scaling, revolving, push/pull, tangency and perpendicularity can also be applied.

  • Trim/Break – Cut and remove sketch curves at the point of intersection.
  • Boolean Operations – Add, subtract, or intersect solid parts to create more complex geometry.
  • Defeature - Remove imprints, rounds, fillets, holes, and pockets, or plug holes and pockets, or create patches and bridges.
  • Midsurfacing – Midsurfacing tools allow users to find and extract 2D sheets from single thickness thin solid geometry

Optimization Options

Inspire offers users a number of topology options:

  • Optimization Objectives - When running an optimization, designers can choose to either maximize stiffness or minimize mass.
  • Stress Constraints - A global stress constraint can be applied to limit the maximum stress in the model during optimization.
  • Displacement Constraints – Displacement constraints can be applied to a model to limit deflections in desired locations and directions.
  • Acceleration loads – Angular velocity and acceleration tools allow users to define the speed of rotation of the entire model and the axis about which it rotates
  • g-Loads – g-Loads tool allow users to simulate a model undergoing acceleration, which imparts a force on all parts of the model
  • Displacement Constraints – Displacement constraints can be applied to a model to limit deflections in desired locations and directions.
  • Temperature Loads – Temperature tool allows users to simulate the effects of temperature changes in a model.
  • Export to OptiStruct – designers can export OptiStruct input files for advanced simulations.

Contacts and Assemblies

Optimize and analyze full parts and assemblies inside of Inspire.

  • The Contacts tool allows users to find neighboring parts and designate whether they should be bonded, contacting, or have no contact.
  • Users can connect multiple parts in a model using the Fastener and Joints tools to add bolts, screws, pins, or sliding pins.

Manufacturing and Shape Controls

Generate design concepts that are not only structurally efficient but also manufacturable using Inspire’s shape controls:

  • Symmetry Planes – Force asymmetric design spaces to generate symmetric optimized shapes.
  • Cyclic Repetition – Create cyclically repeating shapes like propellers or wheels.
  • Draw Directions – Generate shapes that can be easily molded or stamped by applying single or split draw directions.
  • Extrusion Shape Control - Generates constant cross-section topologies in a specified direction.

Analysis

Investigate linear static and normal modes analysis on a model and visualize displacement, factor of safety, percent of yield, tension and compression, von Mises stress, and major principal stress.

Customizable Materials Database

Inspire is packaged with a material library including various aluminum, steel, magnesium, and titanium alloys. Custom materials can also be added.

PDM

Inspire allows users to open models from Teamcenter or Windchill PDM systems. It is also possible to save Inspire models back to the PDM system.

Part Instances

Parent-Child Instances – Individual parts can be copied and pasted as an instance. Whenever one is updated, the other is automatically updated as well. Instancing information can also be imported from CAD files.

Pattern Repetition

When a design space is repeated multiple times in a model using part instances, Inspire will automatically apply pattern repetition to the design spaces so they generate identical shapes.

Interactive Results Visualization

Explore optimized shapes using a simple slider to add or remove material. Users can decide which features are important and then pick the concept design best suited to their needs.

Assembly Configuration

Multiple assembly configurations can be created. These configurations can then be used to evaluate various design scenarios and the resulting concepts.

Final Model Creation

Create PolyNURBS – The create and edit PolyNURBS tools allows users to quickly create free-form solid geometry that is smooth, continuous, and ready for manufacturing.
