if/while in --deaMode

Jul-24-21 19:23:54

I tried to find zero-crossings of a function using  --daeMode, but the result was not was I expected. In "ode-Mode" everything is fine.

Code:


loadModel(Modelica,{"4.0.0"});



loadString("

model ExampleDaeMode 

  Real x;

  Boolean GREATER;

equation

  x= 1.5* sin(time);

  GREATER = x>0.0;

  when edge(GREATER) then

    Modelica.Utilities.Streams.print (\"time = \" + String(time),\"./mytestfile.txt\");

  end when;

end ExampleDaeMode;

"); getErrorString();



setCommandLineOptions("--daeMode");

simulate (ExampleDaeMode, startTime = -0.1, stopTime = 10.0, stepSize=0.01, tolerance=1e-6 , simflags="-lv=LOG_STATS");

getErrorString();

plot ({GREATER,x});

Build.mos

The same problem when removing the "when - block"

In ExampleDaeMode_16dae.c  a function ExampleDaeMode_evaluateDAEResiduals  was defined, but never called.

Does anyone have similar experience with --daeMode ??
