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 assigning an ambient pressure condition to the outlet slot.
00:19
Begin by selecting Boundary Conditions on the Setup tab of the ribbon.
00:24
Left-click the outlet surface to select it.
00:27
Then, on the Setup tab of the ribbon, in the Boundary Conditions context panel, click Edit.
00:34
In the Boundary Conditions quick edit dialog, expand the Type drop-down and select Pressure.
00:41
Leave the Unit set to Pa, and set the Pressure to 0.
00:45
This defines a static gage pressure of 0, which simulates the outlet.
00:50
Click Apply.
00:52
To verify that the pressure boundary condition is correctly applied to the outlet surface,
00:57
in the Design Study Bar, ensure that the Pressure condition appears with a value of 0 Pa.
01:03
Also, in the graphics window, ensure that the color of the stripe on the outlet surface corresponds to the legend.
01:11
With the inlet and outlet boundary conditions properly set,
01:14
the next step is to apply thermal dissipation conditions to the internal components of the device.
