Materials: Air

In this step, we assign Air to the internal flow volume.

1. To start, hide the wall by holding Ctrl, and middle clicking on it:

   

2. Select the flow volume by left clicking on it:

   

3. Click Edit from the Materials context panel:

   

4. On the Materials quick edit dialog, verify the Type is Fluid, and the Name is Air.

   

   In the following two steps, we define the properties of air to vary with temperature. This allows buoyancy (natural convection) to affect the air flow.

5. On the Environment row, click Set.

   

6. Select Variable, and click OK.

   

7. Click Apply.

   

   What it should look like...

8. To verify that the air material is properly assigned, check the Design Study Bar and the part coloring:

   1. On the Design Study bar, confirm the material assignment for the Air part.

   2. The internal air part should be colored to correspond to the Air color in the legend.
