I'm using SystemModeler and I'm trying to understand what is the equivalent for Simulink's Ctrl+drag to create a wire coming out of an existing wire. I am trying to make a wire come out of an existing wire in an electrical circuit (create a node essentially) and I am unable to do this.

  • $\begingroup$ You may get a useful reply, but please be aware that this site is exclusively for Mathematica, rather than other Wolfram products in general, so most people here will probably not know the answer. A better place to ask may be the Wolfram Community, which has forums for all of the Wolfram products, including SystemModeler. $\endgroup$ Commented Apr 16, 2015 at 0:06
  • $\begingroup$ @OleksandrR. Personally I wasn't in favour, but I thought the community decision was that it should be on topic. OP: It is true that few people here have SystemModeler expertise and you'll likely get a faster answer on W Community. $\endgroup$

  • $\begingroup$ @Szabolcs sorry, I hadn't noticed the vote totals for that. I had thought that we were going to say SystemModeler was off topic unless the question has some relationship to Mathematica as well. Okay, so the question is on topic (as you can see, I didn't vote to close). $\endgroup$ Commented Apr 16, 2015 at 8:34

There is no such functionality in Modelica (the underlying modeling language of SystemModeler).

What you can do is connect two "wires" to the same connector on a component, and they will be considered the same signal.

  • $\begingroup$ Thanks. I'll do this, but it's a shame that such a simple feature is not available! $\endgroup$ Commented Apr 20, 2015 at 7:21
  • $\begingroup$ I work on SystemModeler at Wolfram, I'll forward your feedback. Thanks! $\endgroup$
