FMI Design Meeting:
Christian: not every importing tool has an "output interval". Could this not be part of the implementer's guide
Karl: this is a hack, should we not define a standardized annotation?
Torsten: the text for fixed step solvers from FMI 2.0 did not end up in the FMI 3.0 spec
Pierre: I agree with Karl. We have the defaultExperiment.stepSize once, what to do with FMUs that support ME and CS? I would leave it as ambiguous, one could it as a heuristic.
Torsten: for the OM guys, they use fmpy in their CI ...
Christian: wouldn't a new parameter fit for LS-REF?
Pierre: this does not help for the general case. We could add annotations or arguments in a next relesae of the core standard.
Masoud: For variable step solver, one should have something like a maximum stepsize.
Pierre: we should not use the same argument for ME, CS ....
Klaus: I think this was left out intentionally for FMI 3.0
Masoud: when I export an FMU, I fill this FMU with the stepsize with which the model was simulated. For import it gives just an indication. There was a discussion in the SSP Project.
Pierre: It gets difficult for different solvers. I would suggest to create a new field "output recording interval", (as an annotation or xml entry)
Klaus: Is this a timescale of the model?
Torsten: why not state: "stepSize" has no meaning for ME? and for SE??
Pierre: it is also not forbidden to use it as a
Torsten: I will create a suggestion for an annotation
