I have constructed a series of 4 submodels that I am wanting to join together in the main model, except when I place the submodels into the main model the output variables of the submodesl are not added (even after running the submodels). Anyone know how to rectify this?
Following Duncan's suggestion, in case they don't appear after dragging and dropping the sub models into the main model, right click on the submodel within the main model and select Make Variable > From Parameter and choose your output variable.
Have you exposed the outputs of your sub-models as parameters? You need to do that in each sub model then when you drag 'n' drop into the master model they will appear so you can link them.
