So far, there has only been the tag [tag:system-modeler] to be assigned to questions regarding Wolfram's System Modeler (WSM). But as of Version 11.3.0 SystemModel
is a Wolfram Language data type/entity and the system modeling functionality of Modelica, the declarative modeling language used by WSM, has been integrated into the Wolfram Language.
I have created a new tag system-modeling to more clearly separate questions regarding the system modeling functionality integrated into the language from questions regarding the WSM and its interaction with Mathematica/WL.
What do you think: Should there be a separate tag system-modeling?
