Hi Dr Nouidui,I'm having a similar issue as Justin. We are not getting any errors with the solver, only an issue with the asynchronous fmiDoStep. Running EnergyPlus version 9.2 and exporting the FMU from Dymola 2021 version 1.0 FMI.We have no issues running co-simulation with the Moist-Air example FMU. I imported the example FMU into Dymola to compare it with our new exported FMU model and don't see any differences except the stop time. Wondering if there is an issue with our methods of exporting as an FMU.Moist Air Example FMU settings
Our model FMU settings
Is this something you can help me with or should I reach out to Dassault at this point? This behavior is quite expected considering that I'm setting the variable.Best,
Justin

Hi Justin,Two things:
- Could you double-click on the FMU imported block and see in the FMI tab whether the communication step-size of the FMU (fmi_CommunicationStepSize) matches the IDF time step?
- I will generally suggest to use a newest version of Dymola. I recalled that older versions of Dymola needed to have a Sampler (with a sampling time being equal to the EnergyPlus time step) to work. The sampler was added between the input and FMU block to make sure that communications happen at the desired times.
Thanks!

Hi Thierry,Thank you for your response. Unfortunately, my asynchronous problem still persists. Please see below several more screenshots of my settings in Dymola. For reference, I am using EnergyPlus 8.7.0 (32 and 64 bit) and Dymola 2017 FD01 (64-bit).
Best,Justin
