COMSOL5 Multiphysics® is one of the most valuable software modeling tools for engineers and scientists. This book introduces multiphysics modeling techniques and examples accompanied by practical applications using COMSOL5.x. The mathematical fundamentals, engineering principles, and design criteria are presented as integral parts of the examples. At the end of chapters are references that contain more in-depth physics, technical information, and data, these are referred to throughout the book and used in the examples.
