ANSYS FLUENT Tutorial Guide

Tip
You can also right-click the Geometry cell to display the context menu, then select
New Geometry...
2. Set the units in ANSYS DesignModeler.
When ANSYS DesignModeler first appears, you are prompted to select the desired system of length
units to work from. For the purposes of this tutorial (where you will create the geometry in inches
and perform the CFD analysis using SI units), select Inch as the desired length unit and click OK
to close the prompt.

3. Create the geometry.
The geometry for this tutorial (Figure 1.1 (p. 2)) consists of a large curved pipe accompanied by
a smaller side pipe. To create the larger main pipe, you will use the Sweep operation. Sweeping
requires the use of two sketches; one that defines the profile to be swept and the other that
defines the path through which the profile is to be swept. In this case, the profile is a half circle
because the symmetry of the problem means that you do not have to generate the entire pipe
geometry.
a. Set up the plane:
i. Create a new plane by selecting YZPlane from the Tree Outline, then clicking the New Plane
icon in the Active Plane/Sketch toolbar near the top of the ANSYS Workbench window.
Selecting YZPlane before you create the new plane ensures that the new plane is based on
the YZPlane.
