- Populate each of the models with the required data through the preparatory user interfaces of each individual model. The prepared input data for these models is saved to disk. Most OpenMI models will, when input files are saved, also create a small OpenMI standardized XML file (the OMI file), which contains information about the filename for the OpenMI-compliant model component (the LinkableComponent) and the filenames for input files.
- Use an Use an OpenMI editor to add the models to a configuration. Figure 2 illustrates the open source OpenMI Configuration Editor. With this editor, the user selects Add model in the Configuration Editor and browses the file system to find the OMI files. Each time an OMI file has been selected, the OpenMI-compliant model component is loaded and the component reads its input files.
- Connections between the models are created simply by dragging arrows from one model to another. Clicking a connection brings up a link editor dialog (see Figure 3). This dialog has information, obtained from the model components, about which quantities can be provided and which quantities can be accepted. The required combination can then be selected.
- When all the links have been established, the linked system can be run.
- When the model run has completed, the results from the calculations can be investigated through the proprietory user interfaces of each individual model.
