Hi,

In Level-2 S function there is a method “block.SetPreCompOutportInfoToDynamic” which sets the output properties to be inherited. I think it works fine for the case with only one input. What about the case with two inputs? From which input will the output be inherited?

Thanks Senmeis

It should depend on the way the inputs are evaluated for output calculation.

Consider a L-2 S Function which simply multiplies the values from its two input ports. The output properties would depend on the values passed in. For example, if one input port passes in a single input and other passes in a double input, the output would then implicitly be determined to be a double type.
