Launch a geometry or CAD file of an AEC office room model (an ASCII .sat) into CFD for air flow simulation studies.

When designing for the AEC industry, it is common to run air flow simulations on rooms and spaces within architectural models.
00:12
In this example, an office enclosure has been designed in CAD and exported as an SAT, which is ideal for storing 3D model data.
00:21
The eventual goal is to run a simulation of the air flow inside it during a summer design day.
00:27
In Autodesk CFD, there are several ways to transfer your geometry into the program to configure and run a simulation.
00:35
One quick way is to open a geometry or CAD file directly from your local folder.
00:41
Use this method if the CAD system is not available or if you are using geometry from Vault.
00:46
However, if you need geometry associativity, it is better to launch from the CAD system.
00:52
On the Autodesk CFD ribbon, on the Start & Learn tab, Launch panel, click New.
00:59
In the New Design Study dialog, click Browse.
01:03
Next, on your local drive, navigate to and select the file you want to open.
01:09
For this example, in the AEC folder, select AEC-Office-model.sat.
01:15
Then, click Open.
01:17
In the New Design Study dialog, type a name for your study, such as “AEC office model”, and then click Create to open the model.
01:26
The Geometry Tools dialog will most likely appear to indicate that small edges were found,
01:32
but do not remove them because they are an intentional part of the model.
01:36
Close the dialog.
01:39
For this example, the geometry imports in units of meters, and needs to be converted to inches.
01:45
To make this conversion, in the Design Study Bar tree, right-click Geometry and select Change length units to > inch-BTU/s.
01:55
In the Change Unit popup, ensure that Change units is selected.
01:59
Without this option selected, the model geometry will be resized.
02:04
Click OK, and the model updates to reflect the new units.
02:09
You can now begin interacting with the model in CFD.
