Generating Graph Representations for Models

The system of equations after symbolic transformation is represented by a graph. OpenModelica can generate graph representations which can be displayed in the graph tool yed ( The graph generation is activated with the debug flag


Two different graphml- files are generated in the working directory. TaskGraph_model.graphml, showing the strongly-connected components of the model and BipartiteGraph_CompleteDAE_model.graphml showing all variables and equations. When loading the graphs with yEd, all nodes are in one place. Please use the various layout algorithms to get a better overview.
