Hi everyone, thanks for looking at my question.
I'm a beginner in Modelica, and encountered an issue with getting a subset of an enumeration vector:

I've 2 enumerations:

Code:


type TComponent = enumeration(A,B,C,Cost);

type TComponentSubset = enumeration(A,B,C);

and 2 vectors based on the enumeration:

Code:


type TComponentVector = Real[TComponent];

type TComponentSubsetVector = Real[TComponentSubset];

Now in a model, how do I go about multiplying a subset of Out with ComponentPrices in the equation section? I cannot get it to work(last line).

Code:

model test

   parameter TComponentSubsetVector ComponentPrices;

   parameter TComponentVector Out;

equation

   Out[TComponent.Cost] = Out[TComponentSubset] * ComponentPrices; //last line : error = illegal subscript TComponentSubset

end test

Similarly, I tried without success:

Code:

   Out[TComponent.Cost] = Out[TComponentSubset.A:TComponentSubset.C] * ComponentPrices; //last line : error = illegal subscript TComponentSubset

Could anyone tell me what I am doing wrong? Thanks!
