5552	OpenModelica FMUs seem to not report exact continuous states	dafred4991@…	Lennart Ochel	"When compiling a simple model to a CoSimulation (cs) FMU using ""OpenModelica v1.14.0-dev-26515-g3e60c14bfc (64-bit)"", the solution to the continuous states after the next '''fmi2doStep''' seems to depend on whether or not the continuous states have been set to what '''fmi2getReal''' reports for the individual states using '''fmi2setReal'''.

So, it makes a '''difference''' for the next continuous state if you '''extract''' the current continous state, save it, and then '''set''' it to what was just saved.

I'm attaching a Python 3 script to demonstrate this issue using the model ""Modelica.Blocks.Examples.PID_Controller"". The script assumes the corresponding .fmu file to be in the current working directory (see line 26)."	defect	new	high	2.0.0	FMI	v1.14.0-dev-nightly		FMU, fmpy
