Setting the multiplicity of a flow port (SysML)
By default, a new Flow Port has a multiplicity of 1.
To determine the multiplicity of a flow port:
1. Open the Flow Port's Property Pages.
2. Click the Options tab.
3. The multiplicity is shown in the Multiplicity list.
To set the multiplicity of a flow port:
1. Right-click the Flow Port, point to Set, and then click Multiplicity.
2. In the dialog, from the Multiplicity list select the required multiplicity.
If you select Use Defined, specify the required multiplicity in the text box. For example, for a multiplicity of 2 to 4, type 2..4.
3. Click OK.
If the Flow Port is a real redefinition, the Multiplicity is set for the Flow Port in context, without changing the Multiplicity of the Flow Port that is redefined by the redefinition. For more information about redefinitions, click here
