Export FMU for CarMaker

Hello,

How is it possible to export a "Co-Simulation Standalone"-FMU for CarMaker ?

[Priyank Sharma]

You can follow the below documentation to correctly export the model as a Tool-Coupling FMU in R2018b

https://www.mathworks.com/help/simulink/ug/_mw_54e936ec-2fa7-4418-be70-d99c8f91d2bd.html

Actually CarMaker should accept win64 DLL, as you can read in the features and functions list, since CarMaker 5.0, at the following link from IPG Automotive website:

Therefore, if the FMU passes the compliance checker and you are able to re-import the FMU in Simulink and everything works fine, this issue comes from the CarMaker side and should be checked with CarMaker.

Hello,

I still am in contact with IPG. IPG asks in which mode the FMU was created. I am afraid that Matlab generated the FMU in a mode not supported by IPG/CarMaker. I suspect that Matlab generated an FMU in "Co-Simulation Tool Mode", but CarMaker needs one in "Co-Simulation Standalone Mode" (see FMI standard 1.0/2.0). This can be detected, after information from IPG, on the key "needsExecutionTool=True/False" in the FMU.

1) Can you please tell me in which mode exactly the FMU was exported?

If the FMU was exported in "Tool mode", then the additional question:

2) Is it planned to also offer an export in "standalone mode"?

Mathworks currently supports the export of a so-called "tool-wrapper" FMU with an external depoendency on a ML/SL or runtime installation.

You can use https://github.com/CATIA-Systems/FMIKit-Simulink and the Simulink coder to create a standalone FMU (ME or CS in case your model uses a fixed-step solver)
