Transcript
00:03
To create an iso surface, on the Results tab, Results Tasks panel, select Iso Surfaces.
00:11
On the Iso Surfaces context panel, click Add.
00:16
If the casing is not showing, you can restore it by pressing CTRL and middle-clicking anywhere off the model.
00:23
Note that the iso surface has a uniform value, which means it shows the places in the model that have the same value for temperature.
00:31
For a more informative view, you can change this value.
00:35
On the Iso Surfaces context panel, click Edit.
00:39
In the Iso Surface Control dialog, drag the slider to the desired value.
00:45
The iso surface is very useful for locating the min and max temperatures.
00:50
To combine the flow and temperature results into a single view, change the Quantity to Velocity Magnitude.
00:57
This shows the temperature (the Color by result) everywhere a particular value of velocity magnitude occurs (the Iso quantity).
01:06
Drag the slider to change the value of velocity magnitude displayed.
01:11
In this case, drag it to the left to view more of the low-velocity flow.
01:16
To show vectors on the plot, select the Vector settings tab, expand the Results drop-down and select Velocity Vector.
01:25
The resulting 3D electronic cooling simulation tells you that, after flowing over the transformer and capacitors,
01:31
the air impinges on the back wall of the enclosure.
01:35
Also, the moving air removes heat from the components before flowing over the chips.
01:41
You can see that the flow barely removes enough heat
01:43
from the small chips to keep their temperature below the safety threshold of 60° C.
01:49
You now have a thorough understanding of the effects of the flow field and temperature distribution on your electronics enclosure model.
