This exercise teaches how to launch your CAD model into Autodesk® CFD using the Design Study Manger. You will take a brief tour of the Autodesk® CFD interface and gain experience navigating your model, selecting model components, and changing object visibility.
First we should answer the questions from Chapter 2:
What do you know about this design?
What do you want to know about the performance of this design?
What can you change about this design to meet your goals?
The geometry files are located in the Autodesk CFD 2018 Fundamentals\
When launching from Pro/Engineer, a prompt appears about running with interferences. Select "Yes" to proceed.
We discuss Geometry Tools in the next chapter.
With the mouse, rotate, pan, and zoom the model.
Zoom in and out using the mouse scroll wheel. Note that zoom is focused to the mouse curser.
Zoom in on an area with a zoom window using mouse controls (Shift+Left Mouse Button).
Repeat with the one-time zoom command: Navigate (panel) > Zoom (menu) > Zoom Window.
Undo and redo zooming using Previous View and Next View (also on the Navigate panel).
Fit the model to the window with Zoom Displayed (on the Zoom menu).
Change model view to outline , transparent
, and back to shaded
using the Visual Style menu.
Use the ViewCube to examine the model from different angles:

Optional Step: To set the Navigation mode to the CAD system
Hover the mouse over the car. Parts turn green as the mouse moves over them.
Left click on the car body and move the mouse off of the model. The selected part turns red:
Hover the mouse over the selected part. It turns yellow:
Left click on the car body to deselect it.
Hold the left mouse button and drag a rectangle around the end of the car. All parts crossed by the rectangle are initially green. Release the left mouse button and they turn red to indicate they are selected:
Deselect these parts by dragging another rectangle across them:
Right click and choose Select all. All parts turn red.
To deselect all parts, right click and choose Deselect all.
To change the selection mode to surface, right click and choose (Selection type > Surface).
Practice selecting and deselecting surfaces by clicking and by dragging.
To select all surfaces, right click and choose Select all. To deselect all entities, right click and choose Deselect all.
To change the selection type, right click and choose Selection type > Volume.
To hide parts, right click on a part and select Hide. Repeat with other parts.
To resume all parts, right click and select Show all.
To hide a part, hold the Ctrl key and middle click on the part. Repeat with other parts.
To resume all parts, hold the Ctrl key and middle click in the graphic window (off the model).
To undo and redo the previous steps, hold the Ctrl key and roll the scroll wheel slowly. This is useful if you accidentally hide or show a part.
To work with surfaces, right click and select Selection type > Surface. Hide and show surfaces using these steps.
Finish by right clicking and choosing Show all.
