physical interaction

The targeting of the Modelica and Simulink simulation language families by the SysML Extension for Physical Interaction and Signal Flow Simulation (SysPhS) encourages development of SysML models aligned with known practices for a wide class of problems!

Webel Best Practice: SysML/SysPhS: DO NOT use overlapping Connector lines from/to one Port (can be misunderstood as "summed" flow and/or physical node/fork/junction).
