Computer games, driving simulators, control of robots, or optimization of aircraft design: all these applications require suitable and efficient models of their physical processes. This lecture offers an introduction to object-oriented, declarative languages such as Modelica and demonstrates their application for the purpose of computer simulation.

Starting from physical principles, the lecture explains how to model electrical and mechanical systems. The development of extensive modeling-libraries is outlined and illustrated by suitable mechatronic systems. The modeling of further physical domains is briefly sketched.

In addition, the lecture concerns the computational aspects of computer simulation. The processing of the modeling language is explained in detail and the most important algorithms for time-integration are presented.

The corresponding exercise sessions offer the opportunity for the participants to gain their own modelling experience, for instance by creating a mechanic modelling library. Finally, the participants are encouraged to develop a real-time simulation of a vehicle. A high interest in physics but no additional prerequisites are expected for this lecture. All important fundamentals will be explained in the lecture.

The lecture will contain a rich set of exercises at beginners level that shall ease the learning of the modeling language Modelica. Furthermore one or two lecture dates will be seized for hands-on practical exercises to provide further assistance. In addition, the lecture provides a more thourough repetition of fundamental physics, especially suited for CS students.


The lectures slides will be available to print out before the actual lectures takes place.

Exercises and Solutions

There will be 12 exercises. Many of them involve practical modeling work.


There will be an exam of 90min duration.

The following rules apply:

  • Each student is allowed one sheet (having 2 pages) of A4 paper with her or his own handwritten notes. No further notes or books are allowed.
  • No electronic devices are allowed.
  • The exam is written on the provided exam-sheets. Further sheets can be retrieved upon request.
  • Beverages and snacks with low-noise level are ok
