This book can be considered a companion to the two previous publications by the authorHeat Transfer Modelling Using COMSOL Slab to Radial Fin []. For readers aiming to improve their heat transfer modeling skills, one possible sequence is to start with the present book, which will provide a broad perspective of the subject, and then continue to learn in greater depth about the geometry creation stage of model building. Those interested in the detailed exploration of heat transfer modeling of fins are directed to the related book. The same book will also provide an additional source of practice examples for the reader.

This section provides an outline of this work, a road map for the reader to this journey. The purpose is to become familiar with the field of heat transfer modeling through the examples from nature, the world surrounding us, such as animals and plants, but also the human body and the functions that help us live. Asking questions, learning, and trying to understand things are the most basic elements of humanity. If there is one single lesson that the author would like the reader to take from this publication, it is to never stop questioning and leaning; these are the privileges given to all, rich or poor, old or young. There exists nothing such as are we too curious!

The subject in the context of this publication is best understood if followed in the order the material is presented. The author encourages the reader to review the suggested approaches and to work through the presented problems, not only to visualize and understand them, but also to construct them manually as the first step and then use the finite element method tools to model the parts. There are multiple ways to approach each modeling problem, and this includes how one defines the relationships between the component physics. For example, you may decide to define multiple physics and solve each individually, feeding the results of one to the other, or to solve them simultaneously. You may decide to import the geometry or mesh into the modeling tool or to create the model geometry internally, using the built-in geometry-creation features. To gain a deeper understanding of the field, after completion of the related subject matter, the reader should attempt the Examples and Case Studies, exploring different possible ways to tackle the same problem using the building blocks of knowledge provided here.

While information learned from this book may be transferred to other FEM tools, the books primary focus is on COMSOL Multiphysics modeling, with version 5.4 being used. This software consists of a core module and many specialized add-on modules. This book will present techniques which assume availability of the Heat Transfer module and the CAD Import module (or LiveLinkTM module connecting COMSOL Multiphysics with a specific CAD tool).
