- Enable Export iterations;
- If your model operates over a large number of time-steps, you may wish to restrict the date-range for which arc-node output is produced using the Start and End date controls in this dialog; and
- Click OK.
Next, run your model. Enabling Export iterations creates a folder on your Desktop with a name in the pattern:

Graphviz always generates a graphical representation of your arc-node network in two forms. One is displayed on your screen and the other is saved as a file. By default, the version saved as a file is in .GIF format but you can change this using the Output File Type pop-up menu in Figure 8. Note that Graphviz can also generate high-resolution vector-based representations such as .SVG.
