A platform-independent extension of SysML for physical interaction and flow (also known as lumped parameter, one-dimensional, or network models, appearing in simulation platforms such as those supporting the Modelica language and in MathWorks Simulink and Simscape).
Standard coming soon! Beta 2 available to OMG members.
The OMG extension was simplified after these documents were published.
Earlier development work is in a previous version of this page: SysML Extension for Dynamic Simulators.
