Geometry

Draw the Geometry

First, double click "Geometry" in the Project Schematic to bring up Design Modeler. It will prompt you to pick the standard units. From the Problem Specification, we want to use 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 not 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.

Now, click . This tool allows to define a circle by clicking once to define its center point, then click a distance away from the center point to define a radius. Define the circle so its center point is at the origin, define the radius by clicking somewhere inside the rectangle.

We almost have a geometry, but we first need to get rid of the superfluous lines. In the sketching toolboxes window, click Modify > Trim. Now, the segments that are 1. outside of the 1st quadrant, and 2. between the cirle and the origin. You should end up with something similar to the following figure.

Now, we have to dimension the drawing to the problem specification. (Remember! We are only drawing 1/4 of the geometry, so we need to take this into account when dimensioning the figure in ANSYS). In the sketching toolboxes window, click Dimensionins > General
