Hi there,

I'm having difficulties with simulation of the example model from Peter Fritzson book (page 248)
This is the model:

model WhenValidResult
  Real x,y;
equation
  x + y = 5;
  when sample(0,2) then
  y = 7 - 2*x;
  end when;
end WhenValidResult;

and here is the outcome:

>>simulate(WhenValidResult, startTime=0, stopTime=20, numberOfIntervals=500, tolerance=1e-4)
record SimulationResult
resultFile = "Simulation failed.
Error: Internal error generate_compute_output failed
Error: Internal error Generation of simulation code failed
"
end simulationResult;


I have a very similar problem to model and I was wondering if I can do anything about it in OpenModelica.

My system is:
OpenModelica 1.5. RC3
Windows XP Pro 32-bit

Many thanks,
Ivan
