The work is motivated by the need for easy-to-use graphic editing of Modelica models using OpenModelica; as well as needs in teaching where the student should be able to interactively modify and simulate models in an electronic book. Models can be both textual and graphical. The interactive online simulation makes the simulation respond in real-time to model changes; which is useful in a number of contexts including immediate feedback to students.
