Variables
Create and assign variables to parametrize a model. This allows you to quickly iterate and compare design concepts by tweaking the values of the variables.
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.
- Inspire 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.
- 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.

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.

Prevent Recirculation or Backflow near Outlets

If you observe reverse flow or large recirculation regions near an outlet, you can extrude the outlet face to allow the flow reversal to be contained before reaching the outlet boundary.

Click the Geometry tab on the main ribbon.
In the modeling window, double-click the outlet you would like to extrude.

Note: You can also use the Extrude tool on the Geometry ribbon for more complex extrude options. Refer to Extrude for instructions.
Use the white arrows to adjust.
Right-click and mouse through the check mark to exit, or double-right-click.
