Vectors in Algorithm

[Jens Frenkel]

Hello,

I have experienced a strange behaviour of OpenModelica when it comes to vectors and algorithms. I created a small model to illustrate my problem:

model Test

Real a[2];

algorithm

a := {1,2};

end Test;

Unfortunately, the OMC cancels simulation issuing the error message:

record SimulationResult

resultFile = "Simulation failed.

Too few equations, underdetermined system. The model has 2 variables and 1 equations
"
end SimulationResult

Hence, I assume that OMC counts the assignment as one equation although these are two equations (one for each element of the vector)

Kind regards

Jens Frenkel

Hi,

Algorithms in models are not very well supported right now.
We will look into it this year.

You might fix it for now by giving two algorithm statements:
{{{a[1] := 1;
a[2] := 2;}}}

Cheers,
