Proceedings of Modelica2006 arsenal research Vienna, Austria, September 4 th -5 th , 2006 Conference Chair: Dr. Christian Kral Program Chair: Anton Haumer Published by: The Modelica Association (http://www.modelica.org/) and arsenal research (http://www.arsenal.ac.at/) The Modelica Association Modelica 2006, September 4 th – 5 th ii
Preface Preface The first International Modelica Conference took place October 2000, in Lund, Sweden. Since then, Modelica has increasingly become the preferred modeling language for complex multi-domain systems. During this time, the community of Modelica users has grown continuously. This is also reflected in the great response to the Call for Papers of the 5 th International Modelica Conference. This year’s conference will be held on September 4 th -5 th , 2006 in Vienna. From the excellent papers submitted to the program committee, it was finally decided to include 66 oral and 15 poster presentations in the technical program. The technical papers cover thermodynamic and automotive applications, mechanical and electrical systems and the latest developments in modelling and simulation products. Before the conference, there will be five parallel tutorials. These tutorials include an introduction to Modelica, mathematical aspects of modeling, as well as the modeling of electric drives, vehicle and thermodynamic systems. Due to the special features of the Modelica language, such as object-oriented modeling and the ability to reuse and exchange models, Modelica strongly supports an integrated engineering design process. This fact is emphasized by the keynote of Dominique Florack, Executive Vice President R&D of Dassault Systemes, “About the strategic decision of Dassault Systemes to select Modelica to be at the core of Dassault Systemes' open strategy for CATIA Systems”. In various fields Modelica is being used as a standard platform for model exchange between suppliers and OEMs. A key issue for the success of Modelica is the continuous development of the Modelica language as well as the Modelica Standard Library by the Modelica Association under strict observance of backward compatibility with previous versions. The broad base of private and institutional members of the Modelica Association as a non-profit organization ensures language stability and security in software investments. The 5 th International Modelica Conference was organized by the Modelica Association and arsenal research, Vienna, Austria. We would like to thank the local organizing committee, the technical program committee and the reviewers for offering their time and expertise throughout the organization of the conference. We would also like to wish all participants an excellent and interesting conference and hope you will have a memorable experience in Vienna.
