Hi,
Is it legal to connect constraints to flow ports in a parametric
diagram? It is possible under TopCased but not under Artisan Studio!
If I read properly the SysML specification:
"""A property typed by a UML DataType or SysML ValueType is classified
as a value property[...].""" (8.3.2.2 Block)
"""A value property may optionally be shown by a small square
box[...].""" (10.3.1.2 Parametric Diagram)
More over FlowPort is subtype of Port, itself subtype of Property!
So what is the rationale of not allowing it?
If I am wrong, how would you model an electric resistor for Instance? I
thought a resistor has two flow ports of type Electric (containing
current and voltage) and link them by the Ohm and Kirschhoff law...

Best regards,
