About the Conference

The 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, FMI, SSP, and DCP. The program will cover modeling of complex physical and cyber-physical systems, as well as tools, for a wide range of research and industrial applications.

In addition to paper presentations, the conference features several Modelica tutorials for beginners and advanced users, as well as industrial user presentations, vendor sessions, and an exhibition of the conferences’ sponsors. The previous Modelica conference in 2021 was held as an online conference hosted by the Linköping University, Sweden. The previous in-person Modelica conference in 2019 in Regensburg, Germany, was attended by more than 400 participants from all over the world, and we are looking forward welcoming interested participants to this years conference in Aachen.

Scope of the Conference

Modelica is a freely available, equation-based, object-oriented language for convenient and efficient modeling of complex, multi-domain cyber-physical systems described by ordinary differential, difference and algebraic equations. The Modelica language and the companion Modelica Standard Library have been utilized in demanding industrial applications, including full vehicle dynamics, power systems, robotics, hardware-in-the-loop simulations and embedded control systems. The Functional Mockup Interface (FMI) is an open standard for the tool-independent exchange of models and for co-simulation. It is supported by many Modelica and non-Modelica tools and is the key to utilizing Modelica models in non-Modelica environments.

Development in the Modelica Association is organized in Modelica Association Projects:

The projects collaborate to design and maintain a set of coordinated standards for modeling and simulation of complex physical systems.

The Modelica conference will bring together people using Modelica and/or other Modelica Association standards modeling, simulation, and control applications, Modelica language designers, tool vendors and library developers. The Modelica Conference provides Modelica users the opportunity to stay informed about the latest language, library, and tool developments, and to get in touch with people working on similar modeling problems. The conference will cover topics such as the following:
