Creating a digital twin should be easy and intuitive. This book presents twins from different technical fields and describes in detail how to build them. The book is aimed at students or young engineers who want develop and modify the twins without much prior knowledge. The use of the free software tool Simcenter Amesim is introduced. Simcenter Amesim belongs today to the industry standard for the development of digital twins. This program was chosen because it is easy to learn and does not require deep mathematical knowledge or programming skills. We start by creating a simple calculator, then model, for example, mechanical twins such as falling balls, ventilation and tank systems, pipelines, or a solar collector. The physical background is explained for each simulation example, and each simulation example concludes with suggestions for further work. This enables the reader to perform further investigations and exercises with the digital twins.

Prof. Dr.-Ing. Frank U. Rückert studied process and environmental engineering at BTU Cottbus (Germany) from 1993 to 1999. He was a research scientist at University of Stuttgart in the field of computational fluid dynamics, combustion and turbulence-chemical interaction and received his PhD with a thesis on reactions in particle fields. In industry he worked for more than 12 years at Robert Bosch GmbH as a simulation engineer and developer of steam turbines and diesel engines. His special interest lies in the field of simulation and modeling.

In 2015, he started his full professorship in fluid energy machines at the Saarbrücken University of Applied Sciences. He teaches in the fields of power plant engineering, thermodynamics, but also battery systems engineering and statics. He is interested in all kinds of new teaching methods. Currently he is working on a new research project to develop a virtual 3D laboratory for students.

Prof. Rückert and Prof.Sauer published a German preliminar version of the book.
