FLUENT - Flat Plate Boundary Layer Step 2

Step 2: Geometry

Since our problem involves fluid flow, we will select the FLUENT component on the left panel.

Left click (and hold) on Fluid Flow (FLUENT), and drag the icon to the empty space in the Project Schematic. Here's what you get:

Since we selected Fluid Flow (FLUENT), each cell of the system corresponds to a step in the process of performing CFD analysis using FLUENT. Rename the project to Flat Plate Boundary Layer.

We will work through each step from top down to get to obtain the solution to our problem.

In the Project Schematic of Workbench window, right click on Geometry and select Properties. You will see the properties menu on the right of the Workbench window. Under Advance Geometry Options, change the Analysis Type to 2D.

In the Project Schematic, double left click on Geometryto start preparing the geometry. After you launch the web tutorials and FLUENT, you will have to drag the browser window to the width of the largest image (about 350 pixels). To make best use of screen real estate, move the windows around and resize them so that you approximate

At this point, a new window, ANSYS Design Modeler will be opened. You will be asked to select desired length unit. Use the default meter unit and click OK.

Creating a Sketch

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.

Click on the +Z axis on the bottom right corner of the Graphics window to have a normal look of the XY Plane.

 In the Sketching toolboxes, select Rectangle. In the Graphicswindow, create a rough Rectangle from starting from the origin in the positive XY direction (Make sure that you see a letter P at the origin before you start dragging the rectangle. The letter P at the origin means the geometry is constrained at the origin.)

You should have something like this:

Dimensions

Now we will specify the appropriate dimensions and constraints. Below is the summary of geometry of the pipe:

Length: 1 m
Height: 0.5m

Under Sketching Toolboxes, select Dimensions tab, use the default dimensioning tools. Then click on the lines and drag upwards or sideways as the case may be to place the dimensions

Now that we have the sketch done, we can create a surface for this sketch.

Then click on Concept tab in the Design modeler window, then click on Surface from sketches.

This will create a new surface SurfaceSK1. Under the Tree Outline, click on the X-Y Plane  and select Sketch1 as Base Objects and under Details View, click Apply. Finally click Generate to generate the surface.<!-- function popup(mylink, windowname)
