Modelica Association

The Modelica Association is a non-profit, non-governmental organization with the aim of developing and promoting the Modelica modeling language for modelling, simulation and programming of physical and technical systems and processes. 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.

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 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.
