Modelica

Modelica is an object-oriented language designed for modeling complex cyber-physical systems. It enables acausal modeling, allowing components to be connected based on their physical interactions rather than a predefined signal flow. This approach supports the creation of reusable components defined by mathematical equations, facilitating modeling from first principles. The language's structure promotes modularity and abstraction, making it suitable for simulating intricate systems across various domains, including mechanical, electrical, thermal, and control systems. By focusing on the underlying physical laws, Modelica aids in developing accurate and verifiable system models.
