Geometry

Some tips:

• As you follow along in Ansys, you can switch between the video and Ansys easily using Alt+Tab if you are on a MS Windows computer.
• In newer Ansys versions, there is a new Sketch tab in SpaceClaim with slight changes in the sketching procedure which you should be able to able to figure out with a bit of poking around.  
• In SpaceClaim, you can zoom in/out using the mouse wheel, rotate using MMB (middle mouse button) and translate using Ctrl+MMB.

Geometry

Set Up

First, we need to specify that the geometry is 2-dimensional. Right click the Geometry box Image Removed and select Properties. This will open the Properties of Schematic A2: Geometry Window. Under Advance Geometry Options change Analysis Type from 3D to 2D.

...

After the analysis type has been set, we are ready to launch Design Modeler, the design tool in ANSYS. Open Design Modeler by double clicking the geometry box Image Removed. After launching the Design Modeler, you will be prompted to choose a standard unit of measurement. Select Meter as the standard unit, and click OK.

Sketching

We want to sketch on the XY plane. To look at the XY plane, click the positive Z-Axis on the compass in the Graphics window.

...

To begin sketching, click on the Sketching tab in the Tree Outline window. To draw our domain, we will use the Rectangle tool. Click on Image Removed in the Sketching Toolboxes window. In the graphics window, draw the rectangle by first clicking on the origin (make sure the P icon is showing, meaning you are in fact selecting the point), then select a point in the 1st quadrant.

...

Now, we need to draw the wedge outline in the geometry. We will use the line tool to create the wedge. Select the line tool in the Sketching Toolboxes window. Image Removed

Now, we need to remove the extraneous lines that we created. In the Sketching Toolboxes window, click the Modify tab, and select Image Removed. Next, trim the lines indicated by the figure below

The final sketch should look like the image below

Dimensions

Next, we need to add the dimensions for the geometry. In the Sketching Toolboxes window, select the Dimensions tab. Next, select the general dimensioning tool Image Removed. To create a dimension, you first select a line. This will create a dimension for that line. Next, you will need to place the dimension next to the line. See the image below for guidance.

Next, create dimensions for the following 4 lines:

In order to add magnitudes to the dimensions, look to the Details window. You will see 4 dimensions that have been specified. Click on a dimension magnitude, and notice that the corresponding dimension will be highlighted in the graphics window. Use the following diagram to add the dimensions to the geometry.

When the dimensions have been correctly applied, the geometry should look like this:

Line body

First, we need to create a line body of the sketch. In the Menu bar, go to Concept > Lines from Sketches. Click any point on the sketch. In the details window, select Geometry > Accept, then press Image Removed. The line body should now appear in the Outline window

Create Surface

Next, we need to create a surface from the sketch. In the menu tool bar, select Concept > Surface from Edges. In the graphics window, the perimeter of the sketch by either holding CTRL and selecting each line, or holding down the left mouse button and dragging the cursor over each line.

Image Removed

Next, in the details window, select Edges > Apply. Finally, press Image Removed. The geometry should now look like the figure below.

Create a projection

Now, we want to project the center vertical line onto the surface body we just created. This will help us with our mesh. In the menu bar, select Tools > Projection. First, you will need to select an edge. Select the middle vertical line. In the details window, select Edges > Apply

Image Removed

Next, we need to select the surface body for the projection. In the Details window, select Target, then select any point on the surface body.

Image Removed

In Details window, select Target > Apply. Finally, press Image Removed. The line should now be projected on the surface. Now that we have the surface and the projection, we no longer need the line body we first created. In the Outline window, Expand 2 Parts, 2 Bodies. Right click Line Body and select Suppress Body

Image Removed

Now that we have completed the geometry. Save the project, and close the Design Modeler.
