Modelica class diagrams

Question

I am looking for a tool that can (automatically) create class diagrams like this one from Modelica code: https://trac.modelica.org/Modelica/attachment/ticket/85/classDiagramModelicaMedia.png
I need to create a couple of such diagrams and an automated solution would help a lot!
So far, I found this article about Modelica CDV (class diagram viewer):
https://www.modelica.org/events/modelica2006/Proceedings/sessions/Session1c1.pdf
but not a ready to use tool. Any ideas?

Answer 1

This can be done with SystemModeler and Mathematica. The relevant function is a little bit hidden, but it's there. Here's an example:

WSMLink`Library`WSMDependencyGraph["Modelica.Mechanics.Rotational.Components.Spring"]

When hovering over the classes, the full name appears:

The object returned from the function includes a Graph, so you can operate on it with all the graph functionality in Mathematica. Also the function takes the same arguments as Graph, so you can get different graph layouts if needed.

Answer 2

I don't have any specific suggestions, but you might find that a tool like OpenModelica could extract and output sufficient information to construct such diagrams. It seems to have many command line switches for outputting lots of information (debugging and otherwise).
