Hello,

I get an error using OpenModelica (r10977) when I want to simulate the following model.

model ArrayModel

  parameter Integer N=1;

  Real y[N];

end ArrayModel;



model TestModel

  parameter Integer N[:]={1, 2};

  ArrayModel a[2](N=N);

equation

  a[1].y[1] = 1;

  

  a[2].y[1] = 1;

  a[2].y[2] = 1;

end TestModel;

The error message is

Error: Illegal subscript [2] for dimensions 1 in component a[2]

which is related to acessing a[2].y[2]. Acessing only a[2].y[1] does not cause any errors and for this the flattened model has all the declared variables, i.e. a[2].y[2] is defined.

Is this incorrect usage of the Modelica language from me or a bug?

Best regards,

Michael
