    SysML 1.2 Issues: Continuous flows in non-streaming situations with >1 multiplicities

    11.3.2.1 Continuous

    It’s a bit unclear how continuous flows work in non streaming situation, especially with high multiplicities.

    If a continuous flow arrives at a pin with a multiplicity of 2, it would appear that the 1st and 2nd value arriving at the pin would be captured. If the flow is also continuously valued, the two values would be same. The difference between two adjacent samples goes to zero if the delta time between samples goes to zero (assuming differentiability).

    Type: Fix

    To make this capability useful, we’ll need to add a sampling rate to be able to use continuous with >1 multiplicity. If we don’t the specification should have a caveat for >1 multiplicity and differentiable input values.
