Description
I try to use several instances of the same FMU (for Co-Simulation) exported from OM 1.16.0.
I can run the case with our tool DNG 2021, but only with special flags on our tool to run with:
- Stepping multithreaded : false
- Termination multithreaded : false
When these flags are true, the FMU fails as reported here in our issueTracker: https://bitbucket.org/simulage/daccosim/issues/20/a-case-where-the-loglck-file-remaisn-after
I suspect the issue is on the termination part, not the stepping. Probably a problem in the thread-safe mechanism...
Note: the same issue occured in the past with Dymola FMUs and DS solved it.
Note:

Retargeted to 1.18.0 because of 1.17.0 timed release.
