How does FMUComplianceChecker Manage StepIncomplete?

[amveron]

Hello, I would like to know how FMUComplianceChecker deals with an FMU which is in the StepIncomplete status following a do_step call, as in the attached image.

My question fits in a larger context: we have a software which uses FMUs (FMI version 1) as slaves. We observe do_step failures when we call the FMUs with our software. However, despite our best efforts to provide exactly the same input sequence to FMUComplianceChecker, we do not manage to reproduce the do_step failure.

One hypothesis brought by the team developing the FMU slaves is that we do not handle properly the StepIncomplete status and that we should do just as the FMUComplianceChecker since it works (no do_step failure). However, so far and with my limited understanding of the FMUComplianceChecker code, I have not found how this was done.

Thank you for any input! Best regards, Amélie
