### Draw the Geometry

First, right click Geometry and click Properties to bring up the geometry properties menu. The default analysis type of ANSYS is 3D, but we are doing a 2 dimensional problem. Change the Analysis Types from 3D to 2D. Now, right click on Geometry on the project outline and click . This will bring up the Design Modeler. It will prompt you to pick the standard units. From the Problem Specification, we want to choose inch

To begin sketching, we need to look at a plane to sketch on. Click on the Z-axis of the compass in the bottom right hand corner of the screen to look at the x-y plane.

Now, look to the sketching toolboxes window and click the sketching tab; this will bring up the sketching menu.

Before we sketch the geometry, let's note something about the problem specification. The geometry itself has two planes of symmetry: it is symmetric about the x-plane and y-plane. This means we can model 1/4 of the geometry, and use symmetry constraints to represent the full geometry in ANSYS. If me model a quarter of the geometry, we can make the problem less complex and save some computational time.

Okay! Let's start sketching. First, click in the sketching tool bar. This tool defines a rectangle by two points. Place the first point at the origin (Watch for the P- symbol which shows you are placing the point at the origin point), and the other point somewhere in the first quadrant.
