Our Mission

The Modelica Association is a non-profit, non-governmental organization with the aim of developing and promoting open and coordinated standards for system modelling and simulation.

In concrete terms, our current work can be summarized by two main branches:

A more detailed account of our work is provided by the list of Modelica Association Projects below.

Furthermore, the Modelica Association owns and administrates incorporeal rights related to Modelica, including but not limited to trademarks, the Modelica Language Specification, Modelica Standard Libraries, etc., which should be generally available for the promotion of industrial development and research.

Join the Modelica Association

If you share our goals and would like to contribute, you can become a member of the Modelica Association in two ways. You can become

Membership gives you voting rights and enables you to participate in the discussions and technical work of the Association. It is encouraged to join at least one of the MA projects as a guest before becoming a member.

If you are interested, simply contact the Modelica board and explain your motivation. The individual application form provides useful guidance.

Modelica Association Projects

A project to develop, standardize, and promote Modelica, a language to model and simulate multi-domain cyber physical systems in a convenient way.

Modelica Language

A project to develop, maintain, and promote the open source Modelica libraries and model components in many domains based on standardized interface definitions.

Modelica Libraries

A free standard that defines a container and interface to exchange dynamic simulation models using a combination of XML files, binaries, and C code.

fmi-standard.org

A tool independent standard to define complete systems of one or more FMUs including its parameterization that can be transferred between simulation tools.

ssp-standard.org

A platform and communication medium independent standard to integrate models and real-time systems into simulation environments.

dcp-standard.org

A standard to seamlessly integrate physics design models of systems with their electronic controls development.

Modelica Association Bylaws

Individuals interested in joining the Modelica Association must have contributed to an MA project or to other parts of the Modelica Association. A contribution is typically demonstrated by participation in at least two projects or Assembly meetings during the previous twelve-month period (§3 of the bylaws). There is no such prerequisite for organizational membership applications. Individuals and organizations may apply to become a member. If you are interested, simply contact the Modelica board and explain your motivation. Currently, the fee for individuals is 20 Euro/year and for organizations according to the number of employees:

Information on upcoming design meetings and more are published on the Modelica Association calendar. People interested to participate should contact the organizer for details.

History of the Modelica Association

There have been several attempts to define object-oriented languages for physical modeling. However, the ability to reuse and exchange models relies on a standardized format. It was thus important to bring this expertise together to unify concepts and notations. The Modelica design effort was initiated by Hilding Elmqvist, Dynasim AB, and started in September 1996 within an action of the ESPRIT project “Simulation in Europe Basic Research Working Group (SiE-WG)”. The Modelica language has been designed by the developers of the object-oriented modeling languages Allan, Dymola, NMF, ObjectMath, Omola, SIDOPS+, Smile and a number of modeling practitioners in different domains. After 8 three-day meetings, during a 1-year period, a first version of a Modelica language description was put on the web in September 1997. After 19 three-day meetings, during a 3-year period, version 1.3 of the language specification was finished in December 1999. This was the first version used in actual applications. In December 2000 an update of the language, version 1.4, has been published.
