Working with submodels : Plug-and-play modularity : Step 5

Step 5: Load an alternative version of the submodel

<< Previous Step Next Step >>

We now load an alternative version of the submodel.

This new submodel also has a variable called "Soil water" (though in this case it is a Simile variable, not a compartment), and a flow called "transpiration". Note also that this submodel is structurally different from the first submodel: all that matters for plug-and-playability is that the two models have the same interfacing variables: the rest of their structure is irrelevant.

At this stage, the linkages are not re-made. The Soil submodel contains an unsatisfied input parameter "Plant biomass", while the main model contains an unsatisfied input parameter called "Soil water". These undefined elements are shown in red.
