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.
