As the issue is quite complex to resolve we currently have no exact date for when the server will go live again. We will update this page with any new information as soon as this becomes available. In the meantime we would like to apologise for any inconvenience caused by this technical issue. Thank you.


JModelica.org is an extensible Modelica-based open source platform for optimization, simulation and analysis of complex dynamic systems. The main objective of the project is to create an industrially viable open source platform for simulation and optimization of Modelica models, while offering a flexible platform serving as a virtual lab for algorithm development and research. As such, JModelica.org provides a platform for technology transfer where industrially relevant problems can inspire new research and where state of the art algorithms can be propagated from academia into industrial use. JModelica.org is a result of research at the Department of Automatic Control, Lund University, and is now maintained and developed by Modelon AB in collaboration with academia. 

JModelica.org is distributed under the GPL v.3 license approved by the Open Source Initiative.
