A timely introduction to the latest modeling and simulation techniques Object-oriented modeling is a fast-growing area of modeling and simulation that provides a structured, computer-supported way of doing mathematical and equation-based modeling. Modelica is today's most promising modeling language in that it effectively unifies and generalizes previous object-oriented modeling languages and provides a sound basis for the basic concepts. Principles of Object-Oriented Modeling and Simulation with Modelica 2.1 introduces the latest methods of object-oriented component-based system modeling and simulation, and provides a tutorial and reference for the latest version of Modelica complete with a comprehensive overview of application model libraries from many domains. Executable examples are included from many areas-physics, mechanics, electrical systems, thermodynamics, flow systems, computer science, concurrent and real-time processes, biology, ecology, chemistry, economy, etc. Designed for students, researchers, and engineers familiar with basic programming concepts, the text: . Introduces the concepts of physical modeling, object-oriented modeling, and component-based modeling. Includes both visual and textual modeling/programming. Provides a complete yet informal overview of the Modelica language. Demonstrates modeling examples for a wide range of applications. Acts as a reference guide for the most commonly used Modelica libraries. Features the current version of Modelica 2.1 including some anticipated extentions Its flexible format, comprehensive coverage of the field, and practical focus makes Principles of Object-Oriented Modeling and Simulation with Modelica 2.1 an indispensable teaching tool, a timely reference source for modeling and programming with Modelica, and a valuable hands-on guide for doing physical modeling in a broad range of application areas.
