Geometry

Set Up

First, we need to specify that the geometry is 2-dimensional. Right click the Geometry box 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 geometry engine in ANSYS. Open Design Modeler by double clicking the geometry box . After launching Design Modeler, you will be prompted to choose standard units. 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.

...

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 . 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.

...

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

Create Surface

Next, we need to create a surface from the sketch. In the menu tool bar, select Concept > Surface from Sketches. In the graphics window, select any line of the geometry.

Next, in the details window, select Base Objects > Apply. Finally, press . 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 New Sketch icon to create a new sketch

...

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