How to run a flow simulation in an electronics enclosure model, after the materials and boundary conditions have been defined.

In Autodesk CFD, once you have defined the materials and boundary conditions in your electronics enclosure model,
00:10
you can start the flow simulation.
00:13
To begin, on the ribbon, in the Setup tab, Simulation panel, click Solve.
00:20
This opens the Solve quick start dialog.
00:23
On the Physics tab, review the settings.
00:26
Enable Heat Transfer and AutoForced Convection.
00:30
To start the simulation, click Solve.
00:33
While the simulation runs, you can see the results as they are computed in the Output Bar.
00:39
This simulation takes about 10 minutes to complete, but it is sped up for this example.
00:45
Note that for the first 100 iterations, the Temperature results do not change.
00:50
Auto Forced Convection runs 100 flow-only iterations before solving for heat transfer.
00:57
This is possible because the air moves fast enough to eliminate buoyancy effects.
01:02
If buoyancy was relevant, you would solve flow and heat transfer together.
01:07
There are a few things to notice:
01:10
When the initialization is complete and the analysis begins, in the Output Bar, you see the Convergence Plot.
01:17
It shows how the simulation is running.
01:20
When the lines go flat, the solution is no longer changing, and the simulation is complete.
01:26
For a bigger view of the model, click the Output Bar to minimize it.
01:31
Finally, as the results update during the simulation, you can view them using the Results controls on the ribbon.
01:38
In this example, Global is selected, which allows you to control the results appearance on the entire model.
01:44
After a few minutes, the Output Bar displays “Analysis completed successfully” when the simulation finishes.
01:52
Now that you know how to run a flow simulation in an electronics enclosure model,
01:57
you can explore different methods of visualizing the results.
