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: Inspire Fluids
  The minimum system requirements to run Inspire Fluids are listed below.
- Materials and Libraries
  Create materials, assign materials to parts, and organize them into libraries.
- Domain
  Define the solid and fluid domains for the Fluids simulation.
  - Bounding Solid Domain
    Designate one or more parts as the bounding solid domain.
  - Embedded Solid Domain
    Reposition or modify one or more parts between design iterations while keeping the geometry of the static solid and fluid domains constant. This prevents the need to re-identify the fluid volume for each design iteration.
  - Fluid Domain
    Define the fluid domain by identifying it in an imported model or creating one. The fluid domain is created based on the bounding solid domain, not the embedded solid domain.
- 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

Bounding Solid Domain

Designate one or more parts as the bounding solid domain.

Note: If you only need to analyze the fluid part without considering the surrounding geometry, then you can skip defining the solid domain, and go directly to defining the fluid domain. The solver will treat everything that doesn't have a boundary condition as in contact with a solid part.

On the Fluids ribbon, select the Bounding Solid Domain tool.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
Select one or more parts that must remain static during the simulation.
In the microdialog, assign a material.
