Apply a heat dissipation to the transformer on the PCB of an electronics enclosure model.
Transcript

To prepare for running an electronics enclosure simulation in Autodesk CFD, you must first specify the physical characteristics of the model.
00:12
This includes defining boundary conditions,
00:15
such as app lying a heat dissipation (in the form of a volumetric heat generation) to the transformer on a PCB.
00:23
Begin with Boundary Conditions selected on the Setup tab of the ribbon.
00:27
Transformers are modeled as parts, so you also need to change the selection mode to Volume on the Selection panel.
00:35
If needed, hide the exterior casing and air parts so you can access the internal components.
00:41
Press CTRL while middle-clicking both the casing and the air part to hide them.
00:46
Left-click to select the transformer.
00:49
Next, on the Setup tab, Boundary Conditions context panel, click Edit.
00:55
In the Boundary Conditions quick edit dialog, under Property settings, verify that the Type is set to Total Heat Generation.
01:04
Set the Unit to W for Watts, then set the Total Heat Generation to 2.
01:09
Click Apply.
01:11
To verify that the heat condition is applied properly to the transformer, check the Design Study Bar.
01:18
Then, in the graphics window,
01:20
ensure that the color of the stripe on the transformer now matches the Total Heat Generation color in the legend.
01:27
With the heat dissipated by the transformer properly set, the next step is to define the mesh sizing.
