Assign silicon to chips and other components in an electronics enclosure model

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 assigning materials to model parts, such as assigning a material of silicon to chips, capacitors, and a transformer.

00:21

To start, press CTRL and middle click the Air part to hide it.

00:25

Left-click to select the seven computer chips, located on the same PCB.

00:30

Note that you need to hide the heat sink to select the larger chip.

00:34

Next, select the two capacitors and the transformer.

00:38

Then, on the ribbon, in the Setup tab, Materials panel, click Edit.

00:44

The Materials quick edit dialog opens, where you can select the material type.

00:49

For this example, under Property settings, click the Type value to expand the drop-down, and select Solid.

00:57

Next, expand the Name drop-down and select Silicon.

01:01

Click Apply.

01:03

Autodesk CFD also has a compact thermal material that uses a two-resistor model

01:09

to simulate the thermal performance of integrated circuits.

01:12

However, silicon is used here for simplicity.

01:16

To verify that the silicon material is properly assigned, in the Design Study Bar, confirm the material assignment for the Silicon parts.

01:25

Then, in the graphics window, ensure that the color of the seven computer chips, two transistors,

01:31

and one transformer now matches the Silicon color in the legend.

01:36

With this material assigned, you are ready to move on to the next step of preparing your model for a CFD simulation.
