New to Inspire? Learn the basics here.
Tutorials
Start using Inspire with our interactive tutorials.
Parametric Modeling
Create parametric sketches, geometry, and PolyNURBS with construction history and variables.
Implicit Modeling
Create implicit models with primitives, lattices, point clouds, fields, offsetting, Booleans, inverting, smoothing, morphing, and filleting.
Structures
Set up your model and run a structural analysis or optimization.
Motion
Set up and run a motion analysis, plot the results, and export the results.
Fluids
Prepare and run a computational fluid dynamics simulation.
- Overview
  Read a high-level overview of Inspire Fluids with usage notes directly from the Fluids product team.
- System Requirements
  A list of supported operating systems and minimum requirements for hardware and memory.
- Materials and Libraries
  Create materials, assign materials to parts, and organize them into libraries.
  - Parts and Materials Table
    The Materials tool opens the Parts and Materials table, which is used to create, import, assign, and otherwise manage materials.
  - Assigning Materials
    Assign materials to parts using the Materials tool or the right-click context menu.
  - Creating Materials
    A small library of common materials is included in Inspire, but you can also create your own materials.
  - Importing and Exporting Materials
    Use the My Materials tab on the Materials table to import or export materials.
  - Modifying the Standard Material Library
    Inspire includes a default material library of standard materials in your installation directory. This default library can be edited to create a custom library.
  - Changing the Default Material or Library
    Modify the default material or default standard material library in the Preferences.
  - Using Multiple Material Libraries
    Set up an environment variable to use multiple libraries.
- Domain
  Define the solid and fluid domains for the Fluids simulation.
- Conditions
  Include at least one inlet and one outlet, and define the fluid and thermal boundary conditions.
- Run
  Run and review the results of a Fluids analysis.
- Best Practices
  Read workflow tips and usage recommendations from the Fluids product team to help improve your simulation results.
- Troubleshooting
  Need help troubleshooting a problem in Inspire Fluids? Check out our troubleshooting topics.
Design Explorer
Evaluate designs by using geometric variables and applying a design-of-experiments (DOE) or optimization method. We recommend fully constraining your sketch when sketch variables are used in the design exploration.
Manufacture
Set up and run a basic porosity or thinning analysis.
Print 3D
Prepare and run an additive manufacturing simulation, and export a file for 3D printing.
Rendering
Adjust the materials and environment of objects in the scene to create a photorealistic image.
Inspire Python API
Learn how to access the Inspire Python API including online help, quick start demos, and the Extension Manager.
Reference
View the glossary, frequently asked questions, and errors and alerts.
Keyboard Shortcuts and Mouse Controls
Learn keyboard shortcuts and mouse controls for common operations.

Materials and Libraries

Create materials, assign materials to parts, and organize them into libraries.

A material is the physical substance that a part is made of, such as steel, aluminum, or plastic. The type of material does not determine the visual appearance of a part, only its physical properties. Inspire supports two different types of materials: solids and fluids. When performing a simulation using Inspire Fluids, a fluid material is assigned to a part to indicate that the part is filled with the selected liquid or gas.
