Translator from Extended SysML to Physical Interaction and Signal Flow Simulation Platforms, Version 1.1



Raphael Barbau, Conrad Bock, Mehdi Dadfarnia


The design of complex systems often requires engineers from multiple disciplines (mechanical, electrical, production, and so on) to communicate with each other and exchange system design information. Systems engineering models are a cross-disciplinary foundation for this process, but are not well-integrated with specialized engineering information, leading to redundant and inconsistent system specifications. The software provided here translates system models in the Systems Modeling Language (SysML) to physical interaction and signal flow (also known as lumped-parameter, one-dimensional, or network) models on two simulation platforms used in many engineering domains. The translator implements the SysML Extension for Physical Interaction and Signal Flow Simulation (SysPhS) version 1.1, published by the Object Management Group. It can generate Modelica or Simulink/Simscape files from SysML models extended according to the SysPhS specification. This translator is an updated version of the SysPhS 1.0 translator. Several example models are provided to demonstrate the translator in various engineering domains.
