Define inlet conditions in an electronics enclosure model

Define the inlet boundary as an ambient opening in an electronics enclosure model.


Video language:

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.
