Solid Modeling Fundamentals

1-1 OVERVIEW

A simple L-shaped cross section is used to introduce basic solid modeling concepts with ANSYS DesignModeler. These tutorials explore modeling by:

♦Extruding

♦Revolving

A number of additional parametric, feature-based modeling possibilities and formulations are demonstrated in this chapter.

1-2 INTRODUCTION

Solid modeling can be accomplished in a number of ways, and one favorite method involves starting with a two-dimensional shape and manipulating it to create a solid. That is the approach we will use for many of object models created in this book. Figure 1-1 shows an L-shaped cross section that has been variously extruded, revolved, or swept along a curve to produce the solid object models shown.

In the following we use the simple L-shaped section to illustrate these three fundamental solid modeling approaches.

1-3 TUTORIAL 1A – EXTRUSION

Follow the steps below to create a solid model of an extrusion with an L-shaped cross section.

1. Start ANSYS Workbench

3. Select OK – To work in millimeter units.

We will sketch the L-shaped cross section on the XY Plane. Make it 35 m high, 20 m wide with 5 m thick legs.
