UPDATE

Since people don't seem to think that much discussion is needed, let's make this a vote.

Instructions: Vote on precisely one of the two posts below to decide whether SystemModeler-only questions should be on-topic or not. Use only upvotes, no downvotes please.

Note: Questions about how to use SystemModeler from Mathematica (e.g. WSMLink) are on-topic. This is about deciding whether SystemModeler questions not related to Mathematica will also be on-topic. An example would be a question concerned solely with Modelica code, not Mathematica code.

If you believe more discussion is needed or the decision shouldn't be made yet, post an answer.


Original post below:

It is time that a definitive decision should be reached on whether questions about SystemModeler are on-topic for Mathematica.SE. We need a meta post that clearly states the decision and can be linked to. The current uncertainty is clearly bad. People who help out with the review queues need to have a clear answer.

There was a long discussion about this, but no definitive conclusion has been reached. The highest voted answers in that discussion concludes

Weighing the pros and the cons I'd say we pick a wait-and-see approach.

After a wait of two years, it's time to re-evaluate this and reach a definite conclusion.

I was first going to make this a yes/no style vote, but I'm not convinced anymore that people wouldn't want to have some discussion, so I will not make it a vote yet.

Summary of relevant facts:

  • There are 9 questions tagged , asked over a period of nearly two years.

  • Two of these mention Modelica code, one is about WSMLink (i.e. how to access SystemModeler from Mathematica), two are of the tech-support type (i.e. software doesn't work, can't set it up), two are closed, and the rest are general.

  • All questions have been answered.

  • There is one user, Malte Lenz, who is providing most good answers. He is one of the SystemModeler developers. It appears that current SystemModeler expertise may be lacking among MSE regulars. jrhodin, also a SystemModeler developer has also answered questions here.

  • Wolfram Community has 32 threads. Not all questions are answered. Some threads are not questions but usage examples or short tutorials posted by WRI.

  • It appears that there's clearly more SystemModeler activity on Wolfram Community, but not dramatically so. Generally, there is not a lot of visible SystemModeler activity online.

I think most people would agree that questions about how to access SystemModeler from Mathematica (WSMLink) will be on-topic. This discussion is about whether all SystemModeler questions should be on-topic (including ones concerned with Modelica code).

Vote here if you believe all SystemModeler-related questions should be ON TOPIC.


Personally I have only one concern about allowing SystemModeler questions here:

There is not enough SystemModeler expertise. There's a risk that questions won't get answered and the asker will be disappointed. Are we doing a disservice to users by allowing SystemModeler questions and implicitly promising answers? Well, so far all questions have been answered here and it's not 100% clear that posting on W Community is a much better option. So this is probably not a good counterargument.

SystemModeler questions are very rare and will probably make very little impact, so there's no harm in allowing them ...

I lean slightly towards making SystemModeler questions explicitly on-topic.

  • This is a very wise decision and I am very much in favour of it. I am sure I will post some SystemModeler questions soon – magma Aug 13 '14 at 23:44
  • One may go so far as to see SystemModeler as a kind of GUI for interaction with Mathematica. The system analogy might carry quite far and I have seen Bayesian Networks being modeled with Modelica as well - so the interest may be growing eventually. TL;DR quite definitely favorizing your suggestion. – gwr May 31 '18 at 10:44

Vote here if you believe SystemModeler-only questions should be OFF TOPIC.


I think Szablocs review of the SystemModeler issue is very clear and cogent. But I disagree with his conclusion. I am a strict constructionist and would prefer limiting this site to Mathematica alone. Here are my reasons (all mentioned by Szablocs).

  • There is one user, Malte Lenz, who is providing most good answers. He is one of the SystemModeler developers. It appears that current SystemModeler expertise may be lacking among MSE regulars.

    What happens if he stops participating? I don't like having to depend on one person to do all the heavy lifting on a topic.

  • SystemModeler questions are very rare and will probably make very little impact, so there's no harm in disallowing them.

  • There's clearly more SystemModeler activity on Wolfram Community.

    I think Wolfram Community is the proper place for SystemModeler questions.

  • I hijacked your answer a bit. There wasn't a lot of discussion, so I thought a simple vote is better. Do you think this is okay? People who've already voted can modify their vote easily since the posts have been edited. – Szabolcs Jun 23 '14 at 14:28
  • What you've done is fine with me. – m_goldberg Jun 23 '14 at 15:46

    @Szabolcs, m_goldeber, I think it makes sense to route people to Wolfram Community but keep the question here with a link to the cross-posting. I personally think the MSE format is cleaner and leads to more learning than Wolfram Community, but I think a WC posting is more likely to get attention from a dev. It's way past the point of anyone caring, but those are my two cents. – b3m2a1 Mar 16 '17 at 19:47
