2 min.
Transcript
00:03
To prepare for running an ambient room temperature simulation in Autodesk CFD,
00:08
you must first specify the physical characteristics of the model.
00:12
This includes defining boundary conditions, such as applying a heat dissipation (in the form of a volumetric heat generation) to an occupant.
00:21
Begin with Boundary Conditions selected on the Setup tab of the ribbon.
00:26
Occupants are modeled as parts, so you also need to change the selection mode to Volume in the Selection panel.
00:33
Now, you need to hide the wall and air parts so you can access the occupant.
00:38
Press CTRL while middle clicking both the wall and the air part to hide them.
00:43
Left-click to select the occupant.
00:46
Next, on the Setup tab, Boundary Conditions context panel, click Edit.
00:52
In the Boundary Conditions quick edit dialog, under Property settings, verify that the Type is set to Total Heat Generation.
01:00
Set the Unit to W for Watts, and then set the Total Heat Generation to 60, based on an average human at rest.
01:08
Click Apply.
01:10
To verify that the heat condition is applied properly to the occupant, check the Design Study bar.
01:16
Then, in the graphics window, ensure that the color of the stripe on the occupant now matches the Total Heat Generation in the legend.
01:25
With the heat dissipated by the occupant properly set, the next step is to define the mesh sizing.
