# CFD Exercise - Analysis of Airflow through a Duct

## You'll find an additional exercise for CFD simulation

### Access the tuto

Access the [step-by-step exercise here.](https://help.3ds.com/2023x/English/DSDoc/SimXmplUserMap/xmpl-m-DuctFlow-sb.htm?contextscope=cloud)

This example guides you through creating and performing an external fluid flow simulation on the 3DEXPERIENCE platform.

```

This example illustrates a basic analysis of airflow through a duct.

#### You will learn how to:

- Use the Assistant to create a simulation that models the mechanical forces and dynamics of steady-state fluid flow.
- Define a fluid region internal to your model.
- Assign a material to the fluid section, and specify the physics of the flow.
- Apply boundary conditions.
- Create a mesh of the fluid region.
- Request data output for pertinent variables.
- Check and run a simulation.
- Create sensors to display different types of results data.
- Generate plots to view the pressure, flow velocity, and streamline contours of the fluid flow.
