Proceedings

The 11th International Modelica Conference, which takes place at Palais des Congrès de Versailles, is the main event for the Modelica community. Users, library developers, tool vendors, and language designers gather to share their knowledge and learn about the latest scientific and industrial progress related to Modelica and FMI (Functional Mockup Interface).

The fundamental idea behind Modelica is to allow storing modeling knowhow in a high-level formally defined format, i.e., to collect information which you otherwise would find in engineering books only accessible by humans. By allowing convenient reuse of this knowhow by definition of component model libraries, enormous saving in man-hours for setting up simulation studies is achieved. Furthermore, by proper validation of such model libraries, much more reliable conclusions can be made from simulation studies leading to better products and user experience. These considerations lead to the equation-based object-oriented formalism of Modelica.

Since the start of the collaborative design work for Modelica in 1996, Modelica has matured from an idea among a small number of dedicated enthusiasts to a widely accepted standard language for the modeling and simulation of cyber-physical systems. In addition, the standardization of the language by the non-profit organization Modelica Association enables Modelica models to be portable between a growing number of tools. Modelica is now used in many industries including automotive, energy and process, aerospace, and industrial equipment. Modelica is the language of choice for model-based systems engineering.

The FMI standard has been added to the project portfolio of the Modelica Association. FMI provides a complementary standard that enables deployment of pre-compiled high quality models originating from different model formats to a larger number of engineers working with system design and verification.

The format of the conference is somewhat changed compared to previous years. We moved the vendor sessions to the first day of the conference to have two days of purely scientific presentations. Starting the tutorials one hour earlier allowed us to allocate more time and have room for 15 vendors to present their offers compared to 6 at the previous conference.

The program is available in an event app for smartphones, tablets, and PCs. It enables searching for papers with abstracts, authors, and conference rooms. It also allows setting up your own schedule by selecting your favorite presentations.

Taking a walk in the Garden of Versailles is suggested on Tuesday evening. We have allocated a break of more than one hour after the scientific program before the conference dinner is served at the Palais des Congrès de Versailles. This means that you have time to see the Apollo Fountain.

Conference highlights:

• 2 Keynote speeches
• 83 papers in 4 parallel tracks
• 18 posters
• 7 tutorials
• 5 libraries submitted for the Modelica Library Award
• 15 vendor sessions presenting the latest Modelica and FMI tools
• A fully booked exhibition area featuring 20 exhibitors
• Electronic proceedings including all papers and some associated Modelica libraries and models

Finally, we want to acknowledge the support we received from the conference board and program committee. Special thanks to our colleagues at this year’s organizers, Dassault Systèmes and Linköping University, and Amelie Rönngård from Altitude Meetings. The support from the conference sponsors is gratefully acknowledged. Last but not least, thanks to all authors, keynote speakers, and presenters for their contributions to this conference.

We wish all participants an enjoyable and inspiring conference.
