Modelica is an object-oriented, declarative, multi-domain language for component-oriented modeling of complex systems, e.g., systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. Modelica language is a textual description to define all parts of a model and to structure model components in libraries, called packages. Basically, all Modelica language elements are mapped to differential, algebraic and discrete equations. Using Modelica in design process for complex systems is very efficient and provide several benefits results. In Modelica we can model and simulate all types of components such as electrical, mechanical, hydraulic etc. Furthermore, Modelica Association provide standard library which contains a lot of different components.

Introduction To Modelica: This chapter provides a foundational overview of Modelica, its history, key features, and applications. It details the Modelica Standard Library (MSL), discusses various Modelica simulation environments, and offers a comprehensive introduction to the Dymola software, including installation procedures and a basic example (pendulum motion) to illustrate its functionalities. The chapter establishes the theoretical groundwork for the subsequent chapters' practical applications. Syntax of Modelica: This chapter delves into the intricacies of the Modelica language syntax. It covers commenting techniques, identifier and keyword usage, various data types (real, integer, boolean, string, and user-defined), operator precedence and order of evaluation, conditional statements (IF statements and relational operators), the built-in "time" variable, intrinsic operators and functions, and identifies critical points for effective Modelica coding. This chapter is essential for understanding the code used in the subsequent simulations. Simulation of Electrical Networks: This chapter focuses on simulating electrical networks within Dymola. It begins by explaining electrical connectors and then details the modeling and simulation of fundamental electrical components, including resistors, inductors, capacitors, ideal transformers, DC and AC voltage sources. The chapter then moves to practical examples, showcasing the simulation of RC circuits, series RLC resonance circuits, and ideal transformer circuits. The chapter reinforces theoretical concepts through practical examples. Simulation of hydraulic networks: This chapter expands on the simulation principles by applying them to hydraulic systems. It covers hydraulic connectors and the modeling of various hydraulic components like pipes, water tanks, boundary sources/sinks, recovery pumps, booster pumps, and valves. The chapter then explores the simulation of several simple hydraulic networks, including examples of water tanks and water recovery wells, demonstrating the application of logical control within the simulations. Finally, the chapter culminates in more complex simulations like a water recovery and irrigation system and a wastewater pumping plant, showcasing the power of Dymola in handling complex systems. The chapter showcases the versatility of Dymola's applications in different engineering domains. Introduction to Animation Using Dymola: This chapter explores Dymola's animation capabilities. It introduces the fundamental aspects of creating animations within the Dymola environment and makes use of the Multibody Library. A practical example illustrates the process of generating a simulation animation, enhancing the visualization and understanding of the modeled systems. This chapter adds a crucial visual element to the analysis and interpretation of the simulation results.Schlüsselwörter (Keywords)
