Preface

ANSYS Workbench 2023 R2

ANSYS, a product of ANSYS Inc., is a world’s leading, widely distributed, and popular commercial CAE package. It is widely used by designers/analysts in industries such as aerospace, automotive, manufacturing, nuclear, electronics, biomedical, and many more. ANSYS provides simulation solution that enables designers to simulate design performance directly on the desktop. In this way, it provides fast, efficient, and cost-effective product developement from design concept stage to performance validation stage of the product developement cycle. It helps accelerate and streamline the product developement process by helping designers toresolve issues related to structural , thermal, fluid, flow, electrimagnetic effects, a combination of these phenomena acting together, and so on.

ANSYS Workbench 2023 R2: A Tutorial Approach textbook has been written with the intention to assist engineering and practicing designers who are new to the field of FEM. The textbook covers the basis of FEA concepts, modeling, and the analysis of engineering problems using ANSYS Workbench. In addition, the description of the latest tools introduced, the enhancement, and new tutorials based on new and enhanced tools are provided so that the users learn and understand their usage properly and effectively. This textbook covers the following simulation streams of ANSYS:

1. Structural Analysis

Static Structural Analysis

Vibration Analysis

2.Thermal Analysis

Steady State Thermal Analysis

Transient Thermal Analysis

Thermal Stress Analysis

The main features of the textbook are as follows:

•Tutorial Approach

The author has adopted the tutorial point-of-view and learn-by-doing approach throughout the textbook. This approach helps the users learn the concepts faster and apply them effectively and efficiently. Sufficient theoretical explanation has been provided during the tutorial whenever required.

• Real-World Projects as Tutorials

The author has used about 30 real-world mechanical engineering projects as tutorials in this book. This will enable the readers to relate the tutorials to the real-world models in the mechanical engineering industry. In addition, there are about 15 exercises based on the real-world mechanical engineering projects.

• Tips and Notes

The additional information related to various topics is provided to the users in the form of tips and notes.

• Learning Objectives

The first page of every chapter summarizes the topics that are covered in that chapter.

• Self-Evaluation Test, Review Questions, and Exercises

Every chapter ends with Self-Evaluation Test so that the users can assess their knowledge of the chapter. The answers to Self-Evaluation Test are given at the end of the chapter. Also, Review Questions and Exercises are given at the end of the chapters and they can be used by instructors as test questions and exercises.
