Textbook in PDF format

Learn to use modeling and simulation methods to attack real-world problems, from physics to engineering, from life sciences to process engineering. This completely revised and substantially extended second edition answers the most important questions in the field of modeling: What is a mathematical model ? What types of models do exist ? Which model is appropriate for a particular problem ? What are simulation, parameter estimation, and validation ? What kind of mathematical problems appear and how can these be efficiently solved using professional free of charge open source software ? The book addresses undergraduates and practitioners alike. Although only basic knowledge of calculus and linear algebra is required, the most important mathematical structures are discussed in sufficient detail, ranging from statistical models to partial differential equations and accompanied by examples from biology, ecology, economics, medicine, agricultural, chemical, electrical, mechanical, and process engineering. About 200 pages of additional material include a unique chapter on virtualization, Crash Courses on the data analysis and programming languages R and Python and on the computer algebra language Maxima, many new methods and examples scattered throughout the book, an update of all software-related procedures, and a comprehensive book software providing templates for typical modeling tasks in thousands of code lines. The book software includes GmLinux, an operating system specifically designed for this book providing preconfigured and ready-to-use installations of OpenFOAM, Salome, FreeCAD/CfdOF workbench, ParaView, R, Maxima/wxMaxima, Python, Rstudio, Quarto/Markdown and other free of charge open source software used in the book
