    @chrbertsch
    @clagms , @IZacharias , @MBlesken : regarding the Sync meeting: we do not have to have it now, we are also continuing.
    Just rejoin the Webex when you want to sync

    @IZacharias
    @chrbertsch We do not need a Sync meeting at the moment. Still discussing clock issues.
    Christian Bertsch
    @chrbertsch
    @IZacharias : as you look into #1000 now, you can trigger me if you have questions for understanding

    thank you for all the input!
    leaving now, take care!

    Hello,I'm a PhD student working on cosimulation of electrical systems.
    I found the FMU very interesting to meet my expectations.
    However, I have a few questions:

    1. In the field of electrical engineering, we have a lot of software that does not currently integrate the FMI standard. How can we do it in this case?
    2. Can this standard take into account a simulation with a variable time step for the export of an FMU?
    3. Can we make a distributed simulation?
      Thank you very much.

    Hello @ABD16

    1. Which tools are you using? E.g. Saber, MATLAB/Simulink, ... have FMI support. Do you nee import/exoport of FMUs? Best talk with your tool vendor and request FMI support!
    2. Yes, for Model Exchange FMUs and internally for Co-Simulation FMUs
    3. Yes, see e.g. https://bitbucket.org/simulage/daccosim/wiki/Home or https://github.com/NTNU-IHB/FMU-proxy

      (This is a chat for the developers of the FMI standard; please use Stackoverflow with tag "FMI" for questions on the usage of FMI in the future. In case of further questions, plesae answer there)
      Best regards, Christian

    Hello,
    I'd like to know if FMU 2.0 support enumerated types and if so where can I find documentation about it?
    Thank you

    Hi FMI specialists, is there a standard recommendation how to build multi-platform FMUs (one FMU working on Windows and Linux)? We currently Source FMUs and FMPy to recompile. Is this a clear Tool issue oder are there discussion about a standard approach / best practice?
    Christian Bertsch
    @chrbertsch

    Is this a clear Tool issue oder are there discussion about a standard approach / best practice?

    @GallLeo : Currently there is no standard recommendation.
    My colleagues mainly use fmpy or hand-crafted scripts to re-compile source code FMUs
    Some tools can create multi-platformform FMUs
    There was an effert by the INTO-CPS to provide a web-service for that purpos https://github.com/INTO-CPS-Association/fmu-builder , but I think it never really got operational or worked reliably.
    Currently I do not see a standard approach, but we could add it to the FMI3 implementers guide: https://github.com/modelica/fmi-standard/issues/1029#issuecomment-834447076

    @GallLeo @chrbertsch It is very easy to create multi-platform FMUs with OpenModelica (using docker). Simply use the buildModelFMU command and specify the desired platforms as a list in the argument. Ping us on OpenModelica if you want more information.

    hi, the INTO-CPS fmu builder has not been update for some time. I will try and see if we have some resources available. We are using docker images to cross-compile stuff, i.e. https://github.com/dockcross/dockcross

    Hi @CThuleHansen : that would be very good! Thanks! Will you also extend this for FMI3? With the new buildconfiguration compiling source code FMUs shouldbecome much better.

    Hello experts. I have been trying to figure out answer to this question and if this is not the place to ask it let me know. Lets say we have a FMU which is getting inputs from Python and simulating at an interval of 0.001s. Does the FMI/FMU standard allow us to run the FMU multiple times for a same input (so Python provides the input at 0.01s interval and the FMU simulates that 10 times at each step)? Would that be faster since we have reduced the communication interface by 1/10th ?

    hello experts: when I try to execute test case after generating and loading FMU I got this issue: ToolLibs 11:00:17.685 ERROR: tts.core.toolingFramework.toollibLoader.ToolLibLoaderLocal.remote_ExcPrint: Exception: Function fmi2Instantiate is missing in shared library. How I can resolve this issue?

    Hello @zied.zalila:matrix.org : This chat is for the developers of the FMI standard. Your problem seems to be tool specific, of either the exporting or importing tool. So please contact the developers / tool vendors to solve your problem, or use StackOverflow with tag "fmi" and a more detailed description of you problem to ask the community for help.
