Data-specified association between instances of the same submodel

Description

This model demonstrates how to set up an association between submodel instances using a data file containing pairs of instances.

In this example, the association is between one multiple-instance submodel and itself. The submodel could, therefore, represent the nodes on a network, with the asociation indicating which nodes are connected (by arcs) to which other nodes.

Files

Some browsers may attempt to display the model file, rather than open it in Simile; in this case, use the browser back button to return to this page, and use the context menu (invoked by right-clicking on the link) to save the target file to disk.
