I am putting together a basic electrical circuit model in Wolfram System Modeler. While the circuit does not technically need a common node, it makes the circuit easier to explain as branches may be grouped logically.

I am currently trying a 0 ohm resistor as a common node. If there is a way to insert a node on a wire that multiple elements may connect to, I will use that.

I am a developer working on SystemModeler

There is unfortunately no way to create "nodes" in SystemModeler. This is mostly because the concept of a "node" does not exist in the underlying modeling language used by SystemModeler, Modelica.

This has been requested before, and is on our list of features to have in a future version.

I'm not sure what you are asking for, if it's just an electrical circuit you can add a Pin, see Modelica.Electrical.Analog.Interfaces.Pin.

small electrical circuit with a Modelica.Electrical.Analog.Interfaces.Pin

If there are signals of different types (Real, Boolean, Integer, etc) you can use an expandable connector. I'd recommend taking a look at the example BusUsage (Modelica.Blocks.Examples.BusUsage) Bus connector
