Dear Ankit,

Thank you very much for the new reply. Your suggestions have been very useful.

Based and inspired by both of your suggestions, I came up with a solution that seems to be a good compromise given the restrictions I have.

An important restriction is that the connectors in the exterior model must not be connected, both visually and logically. Not connecting them avoids visual cluttering due to the potentially large number of connections, and logically, it's necessary for them to be recognized as input and output ports of the overall system.

Using inner and outer declarations, as in one of the examples, indeed avoids the visual cluttering, but the input and output connectors are still connected logically via the inner and outer variables.

What I did was to define a new connector, containing all the signals each interior model (i.e. IOInterior class in the example below) requires, and used it as interface between the each IOInterior instance and the exterior model IOExterior.

Inside the class IOInterior, I used an additional class, called CableTie, to route the signals into the new connector. Formally, this class is not necessary, but having them allows visual representation of the connections rather than just equations written in text. The equations are written instead within in the CableTie class.

As shown in the following screenshot, Mathematica recognizes the input and output variables defined in the new connector and, therefore, they can be used to calculate transfer functions:

Thank you very much again.

Another element that may be worth clarifying, is that the input and output connectors in the exterior model will remain disconnected.

I'll use the model to calculate transfer functions in frequency space after linearization, and the names of the connectors will appear as inputs and outputs of the transfer function.

Hello Ankit,

Thank you very much for your reply and the example. I appreciate it.

Below there's a modified version of the example, illustrating the situation I refer to. I added another component to the interior model (i.e. inputOutputInterior1.power2) and connected it to the expandable connectors. In order to make it work, in the exterior model I had to add one input and one output in accordance to those changes.

What I want to avoid is having to explicitly write in the exterior model all the inputs and outputs corresponding to the signals in the interior model. In very simple cases this is not too cumbersome, but some of the models I'll use will have at least 10 signals, and I'll need several instances of them.

I tried modifying the example defining an expandable input connector rather than a simple expandable connector, but inside signals don't seem to be accessible this way.

I guess another option would be to use an array of input connectors in the exterior model, but this would not keep the names of the signals in the input models, which are physically meaningful for the final user.

Any additional suggestion would be highly appreciated.

Cheers,

Fabián
