Modelic_Synchronus FMUs not working

[Andreas Heuermann]

As far as I can tell it is not possible to export a Modelica model, that is using features like clocks from Modelic_Synchronus, as an FMU that can be run by a FMU Import Tool.

For example when exporting Modelica_Synchronous.Examples.Elementary.ClockSignals.SubSample as a 2.0 FMU and simulating it with OMSimulator the simulation will issue warnings and the results are completely wrong.

setCommandLineOptions("--std=3.5 --simCodeTarget=Cpp"); getErrorString();

loadModel(Modelica, {"3.2.3"}); getErrorString();
loadModel(Modelica_Synchronous); getErrorString();

buildModelFMU(Modelica_Synchronous.Examples.Elementary.ClockSignals.SubSample, version="2.0", fmuType="me"); getErrorString();

system("OMSimulator Modelica_Synchronous.Examples.Elementary.ClockSignals.SubSample.fmu"); getErrorString();

The result of model.sample1.y should be a clocked version of a sine curve.
I have added the modelDescription.xml to this ticket.

Or is it just that I exported the FMU wrong and it is possible? The Cpp should be able to use clocks in FMUs, but it didn't change anything for me when adding simCodeTarget=Cpp.
