fmpy/examples/custom_input.py with FMI3

[autoantwort]

First of all, thank you for this awesome project!

I found the example fmpy/examples/custom_input.py very helpful, but wanted to use a FMI 3.0 FMU and it seems that the API changed.
I propose to add another example that uses a FMI 3.0 FMU.

I second this!
It would be very helpful to have a FMI 3.0 example, as I can't get sufficient information initializing such a FMU.

Best regards,
Konstantin

To get you started, I was able to just make a few simple swaps to my script for FMI2 (based on the custom_input.py file you mentioned). The items to change were:

• fmi2.FMU2Slave to fmi3.FMU3Slave
• Remove fmu.setupExperiment as that seems to have been removed.
• setReal to setFloat64
• getReal to getFloat64
• Comment out derivative as that changed and I don't understand it yet.

You can find two FMI3 examples here.
