A common situation in industry is that a system model (here a composite model) is composed of several submodels which may have been developed using different tools.FMI is one important technology for exporting/importing models between tools and/or connecting them via co-simulation.TLM based modeling and co-simulation is another important technique for modeling, connecting, and simulation of especially mechanical systems, which is simple, numerically stable, and efficient.A number of toolspecific simulation models, such as Modelica models, SimuLink models, Adams models, BEAST models, etc., have successfully been connected and simulated using TLM based co-simulation.However, previously there was no general open source tool for creation, graphic editing, and simulation of composite models connected via FMI or TLM based co-simulation.In this paper we present a graphical composite model editor based on OpenModelica which is integrated with the OpenModelica and the SKF TLM co-simulation frameworks to support both FMI and TLM based composite model editing and simulation.The editor supports creating, viewing and editing a composite model both in textual and graphical representation.The system supports simulation of composite models consisting of sub-models created using different tools.
