Conference:Proceedings of the 9th International MODELICA Conference; September 3-5; 2012; Munich; Germany
Publication type: Conference proceedings
Introduction:The 9th International Modelica Conference is the main event for users; library developers; tool vendors and language designers to share their knowledge and learn about the latest scientific and industrial progress related to Modelica; to the Modelica Association and to the Functional Mockup Interface.

Highlights of the conference:

  • 80 regular papers; 22 poster papers; and 6 libraries for the Modelica Library Award.
  • 2 Keynotes.
  • 8 tutorials (3.5 hours each; descriptions).
  • 10 vendor sessions (45 min. each) where the latest news of Modelica and FMI tools are presented.
  • 17 exhibitors in the exhibition area.

Please note that to some of the papers a Modelica library or model is attached. These files are accessible in the electronic proceedings.

The conference provides also the most important news from the Modelica Association:

  • The new version of the Modelica language version 3.3 was released on May 9; 2012. There are several papers and a tutorial at the conference that discusses and demonstrates the new features.
  • The working process of the Modelica Association has been changed and the work is now organized in Modelica Association Projects (MAP) with an extended board. More details are given in the presentation “Modelica News” on Tuesday; Sept.4; 9:10 – 9:25.
  • The further development of the FMI (Functional Mockup Interface) standard is performed in a MAP. A draft version of FMI 2.0 will be available before the conference. An overview of this new version is given in a conference paper. In two sessions; applications and tool support for FMI are presented and discussed.
  • Since July; the Modelica Association provides an open source FMI compliance checker for FMI 1.0 at Its purpose is to check exported FMUs for validity. The checker can also produce reference simulation results with a fixed step explicit Euler method. Shortly after FMI 2.0 is released; the compliance checker will also be available for FMI 2.0.

Finally; we want to acknowledge the support we received from the program board and program committee. We are grateful for the help by the Modelica Association and Monika Klauer from DLR. Last but not least; let us thank all authors for their contributions to these proceedings. We wish all participants an enjoyable and successful conference.
