Because a SubModel is effectively a separate model (as opposed to a Container), you may choose to use different extension modules in a SubModel than in the outer model. For example, your SubModel may require the Contaminant Transport Module, while the outer model may not.
When you create a SubModel, the modules that are activated by default are the same as those that would be activated by default if you created a new model. (These defaults are set by the user by pressing the Set as Default button when activating modules in the Modules tab of the Options dialog).
To specify the modules that will be activated for a SubModel, press the Modules… button on the SubModel dialog. The following dialog will be displayed:
All extension modules that you are licensed to use appear in the dialog. If your license does not allow you to use a particular module, it will not be listed. You can activate and deactivate modules that you are licensed to use by clicking the Active checkbox.
If you deactivate a module, the specialized elements associated with that module will be deleted from your SubModel (if any are present) and any associated menu options will be removed in the current file. If you make a module active, the various options associated with that module are made available again.
Note: If a module that is active in a SubModel has special options
(that are normally accessed via a tab in the Options dialog for a
standalone model), these options will appear in a tab on the Modules dialog for
the SubModel.
