Transcript
00:03
To prepare for running an electronics enclosure simulation in Autodesk CFD, you must specify the physical characteristics of the model.
00:12
This includes defining boundary conditions, such as defining an inlet boundary as an ambient opening.
00:19
To begin, on the ribbon, in the Setup tab, Setup Tasks panel, click Boundary Conditions.
00:26
To make sure all the parts are visible, hold CTRL while middle clicking anywhere off the model.
00:32
Left-click to select the inlet surface.
00:35
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, and select Pressure.
00:50
Expand the Unit drop-down and select Pa.
00:54
Then, set the Pressure value to 0.
00:57
Click Apply.
00:59
Next, apply the inlet temperature.
01:02
To select the inlet surface again, on the Setup tab, Selection panel, click Select Previous.
01:09
On the Boundary Conditions context panel, click Edit.
01:13
In the Boundary Conditions dialog, in the Type row, select Temperature.
01:19
Verify that the Units are Celsius.
01:22
Then, set the Temperature to 25.
01:25
Click Apply.
01:27
To verify that the boundary conditions are properly assigned to the inlet surface, check the Design Study Bar.
01:34
If needed, drag the right edge of the Design Study Bar to see both conditions.
01:39
Then, ensure that the two stripes on the inlet face correspond to the boundary conditions types in the legend.
01:46
With the inlet boundary properly assigned, the next step is to assign a boundary condition to the outlet slot.
