Note to Cornell students enrolled in MAE 4272: You can skip the geometry and mesh steps. Download the mesh here. Unzip the downloaded file. After unzipping, you should see a file called pipe_flow.wbpj and a folder called pipe_flow_files. Double click on pipe_flow.wbpj and then skip to Step 4: Setup (Physics). |
Since our problem involves fluid flow, we will select the FLUENT component on the left panel.
...
In the Project Schematic of the Workbench window, right click on Geometry and select Properties . You will see the properties menu on the right of the Workbench window. Under Advance Advanced Geometry Options , change the Analysis Type to 2D.
In the Project Schematic , double right click on Geometry and select Create New DesignModeler Geometry to start preparing the geometry. To make best use of screen real estate, move the windows around and resize them so that you approximate

At this point, ANSYS DesignModeler will open in a new window, ANSYS Design Modeler will be opened. You will be asked to select the desired length unit. Use the default meter unit and click OK .
The geometry is a rectangle of length L = 6.045m and height R = 2.94 x 10^-2 m .
Creating a Sketch
| Note |

For users of ANSYS 15.0, please check this link for procedures for turning on the Auto Constraint feature before creating sketches in DesignModeler. |
Start by creating a sketch on the XYPlane . Under Tree Outline , select XYPlane , then click on Sketching right before Details View . This will bring up the Sketching Toolboxes .
...
In the Sketching toolboxes, select Rectangle . Hover the cursor near the origin until you see a letter P. This means the cursor is coincident with a point, in this case the origin . Then drag the cursor to draw a rectangle.
Note: You do not have to worry about dimensions for now, we will specify them properly in the later step.
...
Dimensioning of the geometry is shown below:
Under Details View on in the lower left corner, input the value for dimension appropriatelyvalues for the appropriate dimensions. Then hit enter each time each dimension is entered.
V1: 0.0294 m
H2: 1.83 m
H3: 4.27 m
H4: 6.045 m
...
Now that we have the sketch done, we can create a surface for this sketch.
Then click on the Concept tab in the Design modeler DesignModeler window, then click on Surface from sketches .
