Visualize 3D flow with iso surfaces in an AEC model

Visualize 3D flow through an AEC model by creating an iso surface.


00:03

In Autodesk CFD, you can create an iso surface to visualize simulation results in 3D,

00:10

showing value and the physical shape of the flow characteristics.

00:14

This complete view can help you to better understand the flow distribution in your AEC model.

00:20

This example simulates air flow in an office cooled by A/C on a summer design day,

00:25

with a seated occupant to help assess the ambient comfort.

00:29

In this case, a previously created results plane needs to be deleted.

00:34

To delete a plane, on the ribbon, Results tab, in the Planes context panel, click Remove.

00:42

To create an iso surface, on the Results tab, Results Tasks panel, select Iso Surfaces.

00:50

Then, on the Iso Surfaces context panel, click Add.

00:54

Note that the iso surface has a uniform value, which means it shows the places in the model that have the same value for velocity magnitude.

01:03

For a more informative view, you can change this value.

01:07

On the Iso Surfaces context panel, click Edit.

01:11

In the Iso Surface Control dialog, drag the slider to the desired value.

01:17

Press SHIFT and the middle mouse button to rotate the model.

01:21

In this case, the specified velocity shows a large volume of air moving under the desk and behind the occupant.

01:28

Iso surfaces are a useful tool for AEC simulations,

01:33

because they clearly communicate a complete, 3D view of flow distribution in the space.
