Visualize 3D temperature field with iso surfaces in an AEC model

Visualize a 3D temperature field in an AEC model using iso surfaces, and combine temperature and flow into a single view.


00:03

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

00:11

This enables you to understand the temperature distribution within the AEC model space, particularly the temperature of any occupants.

00:20

You can also combine temperature and flow into a single view.

00:24

The model in this example simulates air flow in an office cooled by A/C, with a seated occupant.

00:31

An iso surface is already created to visualize flow.

00:35

Now, map temperature to the iso surface to create a 3D view of the temperature field, and to visualize flow and temperature together.

00:44

On the Results tab, Results Tasks panel, select Iso Surfaces.

00:50

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

00:54

In the Iso Surface Control dialog, change both the Iso quantity and the Color by result to Temperature.

01:02

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

01:10

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

01:14

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

01:20

In this case, drag it to the left for a better view of the lower temperatures inside the model room.

01:26

To combine the flow and temperature into a single view, change the Quantity to Velocity Magnitude.

01:32

This shows the temperature (the Color by result) everywhere a particular value of velocity magnitude occurs (the Iso quantity).

01:41

Drag the slider to change the value of velocity magnitude displayed.

01:45

In this case, drag it to the left to view more of the low-velocity flow.

01:50

This combined view is a useful way to visualize and understand the three-dimensional flow and temperature distribution.

01:58

Notice the thermal plume coming off the occupant.

02:01

This makes sense because the occupant is warmer than the surrounding air.

02:06

Finally, to display temperature on the occupant, on the ribbon, in the Results Tasks panel, click Global.

02:14

Then, expand the Global Result drop-down, and select Temperature.

02:19

You now have a thorough understanding of the effects of the flow field and temperature distribution on the occupant.
