[SOLVED] How to modify an outer parameter in two instances declaration?

How to modify an outer parameter in two instances declaration?

I have developed a submodel that I am using throughout my project and it has an outer parameter:

model Submodel

    outer parameter Real toto;

    [...]

end Submodel;

Then, for each component of my project, I just start with the definition of the inner parameter:

model Model

    inner parameter Real toto = 1;

    Submodel submodel1;
    Submodel submodel2;

    [...]

end Model;

That's really convenient for my project and I don't want to modify this, unless there's a clean workaround. Just to be clear, I actually have more than two instances, hence the use of an outer parameter.

Now, the issue is that I have a specific model that requires the use of two different values for the parameter toto, for two instances of the submodel. I thought of something like:

model SpecificModel

    Submodel submodel1(toto=1);
    Submodel submodel2(toto=2);

    [...]

end SpecificModel;

But Dymola throw me out with an Outer component with non-empty modifier. Any idea how to go around the outer or redeclare the parameter itself in the instance declaration?

Solution

You cannot directly do that, but have to introduce an extra layer:

model SpecificModel

    SpecificAdapater1 submodel1(toto=1);
    SpecificAdapater2 submodel2(toto=2);

    [...]

end SpecificModel;

model SpecificAdapater1
    inner parameter Real toto;

    Submodel submodel1;
end SpecificAdapater1;

model SpecificAdapater2
    inner parameter Real toto;

    Submodel submodel2;
end SpecificAdapater2;

It might be that there should be more differences between SpecificAdapater1 and SpecificAdapater2 - or on the other hand that they could be the same class.
