MSL Electrical machine model only works in the Linux Jenkins tests, but not with -nfAPI

[Francesco Casella]

Please consider the Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMEE_Generator_MultiPhase model of MSL 3.2.3. It simulates correctly in our ​Jenkins test, but if you run it with the latest Windows nighly, lots of errors are generated and the simulation breaks around time = 6, with smee3.stator.electroMagneticConverter.singlePhaseElectroMagneticConverter[2].Phi.re blowing up to infinity.

@adeas31, this is quite odd, can you please check what happens here?

[Adeel Asghar]

With the current master version it fails to compile the simulation executable. Here is the compile log,

What do you mean by "master" version? Both the ​newInst and ​master reports on Jenkins are fine.

[Mahder Alemseged Gebremedhin]

I can not reproduce this as of ​46dda5311a1760eb3f9ce892531711f3cc2f18b2.

Compilation and simulation completes successfully for both old and new front-ends on my machine. I am using the 64 bit version.

Can you verify again with this version just to make sure? I am using OMDev directly to compile from source and you are using nightly. If we still have the problem then I will have to check the nightly and see what difference we have in configurations between the two.

[Francesco Casella]

Will do ASAP. But this is obviously an OMEdit issue, if you use OMDev you are following a different path.

[Adeel Asghar]

I debugged a bit more and for sure it is not OMEdit issue. Here is the script to reproduce the issue,

setCommandLineOptions("-d=newInst");
getErrorString();
setCommandLineOptions("-d=nfAPI");
getErrorString();
loadModel(Modelica);
getErrorString();
simulate(Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMEE_Generator_MultiPhase);
getErrorString();

Surprisingly the problematic part is setCommandLineOptions("-d=nfAPI");. If you remove this line everything works fine. @adrpo why is this flag making the simulation terminate?

[Adrian Pop]

Should be fixed with PR:
​​https://github.com/OpenModelica/OpenModelica/pull/6719

[Francesco Casella]

Works fine, thanks @adrpo!
