Hi Eric,

I am glad support for the Media library is useful for you. Currently, two specialized features used in the Fluid library is not fully supported: homotopy-based initialization and stream connectors.

We are aware that the Fluid library is sought after by many users and the development team is hard at work with including support for this. Though I cannot give you any exact dates, it is a high priority and we hope to see the library supported in the near future.

Is there a stable earlier release for the Fluid library that can be used? (After all, the problem persists as the Fluid library is not included in Version 12)

Stream connectors afaik have been introduced in 2009 (Version 3.1) only - and before that there seems to have been a stable version:

The FluidPort connector referenced in the paper above does not have stream connectors.

Hi Ankit,

Thanks for the clarification.

So, while the MFL is not being supported, I am curious: Would working with an imported FMU work out in System Modeler (cf. System Modeler Documentation: FMI - Using an Imported FMU)? As a preliminary workaround: OpenModelica does support the MFL and I assume that working with the FMU essentially is wrapping interfaces around C code?

Can Mathematica work with imported FMU (i.e. make fully use of the FMI) or is that restricted to System Modeler interaction? (The documentation suggests that currently only Export is supported)

Regards,

Guido

Great news! Thank you for that quick response, Ankit.

You will need SystemModeler to open the FMU, you cannot import FMU in Mathematica as of now.

But I assume, that once imported (with input/output wrappers) into System Modeler one could run the model using Mathematica as usual?

Thanks,

Guido
