Define the supply flow rate in an AEC model

00:03

To prepare for running an ambient room temperature simulation in Autodesk CFD,

00:08

you must specify the physical characteristics of the model.

00:12

This includes defining boundary conditions, such as a supply flow rate.

00:17

To begin, on the ribbon, in the Setup tab, Setup Tasks panel, click Boundary Conditions.

00:24

To make sure all the parts are visible, hold CTRL while middle clicking anywhere off the model.

00:30

Left-click to select the supply surface for the flow.

00:34

Then, on the ribbon, in the Boundary Conditions context panel, click Edit.

00:40

In the Boundary Conditions quick edit dialog, under Property settings, click the Type value to expand the drop-down,

00:47

and select Volume Flow Rate.

00:50

Expand the Unit drop-down and select ft3/min.

00:54

Then, set the Volume Flow Rate value to 150.

00:58

Click Apply.

01:00

Next, apply the temperature condition.

01:03

To select the supply surface again, on the Setup tab, Selection panel, click Select Previous.

01:10

On the Boundary Conditions context panel, click Edit.

01:15

In the Boundary Conditions dialog, in the Type row, select Temperature.

01:20

Verify that the Units are Fahrenheit.

01:23

Then, set the Temperature to 65.

01:26

Click Apply.

01:28

To verify that the boundary conditions are properly assigned to the supply flow inlet, check the Design Study Bar.

01:35

If needed, drag the right edge of the Design Study Bar to see both conditions.

01:41

Then, ensure that the two stripes on the supply surface correspond to the boundary conditions types in the legend.

01:48

With the supply flow rate properly assigned, the next step is to assign a boundary condition to the return.
