     description="This exercise book provides an introduction to the simulation practice in Engineering using Modelica. To this end, it contains a series of thirteen independent hands-on assignments of increasing complexity. Each assignment contains the description of a system and a mathematical model of the system’s behavior. The proposed task often consists in describing this mathematical model in the Modelica language and simulate it. In some assignments, the system’s behavior is described as an atomic model, without internal structure. Some other assignments ask to design and implement a model library, and to compose the system model by instantiating and connecting components from this model library."

+    description="Thinking in Systems, Not Code: Using Modelica to Model and Understand Complex Systems presents Modelica as more than a programming language—it introduces a system-level way of thinking about modeling and simulation. Rather than focusing on syntax, the book explains how complex systems are framed through structure, boundaries, and physical relationships, and how behavior emerges from interacting components. Using examples from energy systems, electric vehicles, thermal and fluid systems, and system dynamics with stocks, flows, and feedback loops, it shows how equation-based, acausal modeling enables reusable, scalable, and domain-independent models. The book is suitable both for engineers new to Modelica who want to understand the underlying modeling philosophy, and for experienced users interested in a deeper perspective on model structure, abstraction, and how modern Modelica tools transform equations into executable simulations."
