The output I get from my test script is as follows. We've previously reported the warning messages about the floating-point constant, so that's a different issue. The issue here is something is causing the model executable to segfault here, when it should really just be exiting with an error code (or continuing, even). Something is apparently causing the solver to segfault from the 'solveNewton' function in libSimulationRuntimeC.so. Surely that isn't intended? The actually command-line being run here (after compilation of the model) is {{{ ./PhysicalParticleSystem -override startTime=0.0,stopTime=31536000.0,stepSize=300.0 -s dassl -lv -LOG_SUCCESS,-stdout -f PhysicalParticleSystem_init.xml -r PhysicalParticleSystem_res.mat -nls newton }}} The version is OpenModelica 1.15.0~dev-9-g34505da. And here is the output, including some extra output from the compilation process, wrapper script, etc.: {{{ john@thunder:~/src/solartherm/tests$ python TestPhysicalParticleSystem.py Notification: Automatically loaded package Complex 3.2.2 due to uses annotation.
