Geometry

Overview

The geometry is created in the following steps:

...

-Create "Surface Body": Create a "Surface Body" from the sketch. This is analogous to, say, extruding a sketch to create a 3D body. We always go from a "sketch" to a "body" in DesignModeler. Here the "body" is 2D and referred to idiosyncratically as "Surface Body".

Specify Geometry as 2D

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, you can dismiss the Properties window. We are now ready to launch DesignModeler, the drawing tool in ANSYS. Open DesignModeler by double-clicking the geometry box . Twiddle your thumbs until the DesignModeler window comes up. 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.

...

Now we will make the second segment of each edge to be of the same length (this will automatically ensure that the first segments are also of the same length). Go to the Constraints tab and select "Equal Length."  Click on the top, right partition first. Then click on the bottom right partition. This will make these segments the same length ensuring that both the top and bottom edges are split at the same location. If you made a mistake,there is an undo button at the top left (caveat: this undo button works only in the sketching mode).

Dimensioning

The next step in creating the domain will be adding dimensions. In the Sketching Toolboxes window, select Dimensions > General. First, click the left segment of the upper edge of the rectangle, then drag the cursor to place the dimension above the line. Repeat this process for the right segment of the upper edge. Last, dimension the left edge as shown below.

...

We can set the dimension in the Details View window. In the Details View window, change H1 to 5.76, H2 to 2.88, and V3 to .06. You can zoom in/out using the middle mouse wheel. You can move the dimensions by selecting Dimensions > Move and then dragging the labels by grabbing them with the mouse.

Surface from Sketches

Recall that we need to create a 2D "Surface Body" from the sketch. To accomplish this, look to the top menu and select Concept > Surfaces From Sketches.

...

Save the project by selecting File > Save Project from the main menu. Close DesignModeler. We are ready to move on to the meshing step.
