Array as fmu input

106 views Asked by At

i'm trying to export a simulink model as fmu. It has some constant parameters and takes as input a vector of velocity. The problem is that the version 2.0 of fmi does not support this data structure.

I also tried the 3.0 version, but without success (In theory is supported by the standard). What i want to do is to use this exported model in a framework named mosaik and use different parameters and array of velocities. Do you have any suggestions?

Which way do you use to export FMUs?

There is native FMI 3.0 support by Mathworks starting in R2023B. This should have array support. Citing from https://de.mathworks.com/help/slcompiler/release-notes.html "The following FMI 3.0 features are supported for an FMU in Simulink: ... Vector and array support" However this is not (yet?) documented on https://de.mathworks.com/help/slcompiler/gs/export-simulink-models-to-functional-mock-up-units.html I do not have experience with this. Please check with the Mathworks support.

There are other solutions to export FMUs from Simulink, such as FMI-Kit https://github.com/CATIA-Systems/FMIKit-Simulink which support export of array variables for inputs and outputs.

With Mosaik you mean https://gitlab.com/mosaik/components/mosaik-fmi. Does this support FMI 3.0?
