2 min.
Transcript
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.
