Export model as FMU for Cosimulation stand-alone

Hello,

i need to export a Simulink model as FMU for Cosimulation stand-alone (not FMU for CoSimulation).

Is there a way to do this in MatLab 2018b?

The Tool-Coupling Co-Simulation FMU Export for Simulink seems just to support FMU for CoSimulation.

Thanks in advance

Kevin

Beginning with R2020a, you can export your Simulink model as a standalone FMU with Simulink Compiler. When a third-party tool runs the FMU, no MATLAB or Simulink license will be required.

This is great progress. It works for Simulink models with fixed-step solver, not with variable step solvers.

The Tool coupling Co-Simulation is a so called "tool wrapper FMU" with an external dependency to a ML/SL installation or runtime.

For Simulink Models you can create stand-alone FMUs with https://github.com/CATIA-Systems/FMIKit-Simulink using the Simulink coder.

This works for ME FMUs or CS FMUs in case your Simulink model uses a fixed step solver.

@Christian Bertsch Is it possible to create stand-alone FMU using Variable step solver ?

Technically I see no problem, but this is a buisiness decision of MathWorks, if and when they want to release such a feature. Please ask your Mathworks contacts for more information. Only Mathworks could create a CS FMU with the original Simulink variable step solver as this is their IP.

(As a workaround, you could export a model exchange FMU (with FMI-Kit https://github.com/CATIA-Systems/FMIKit-Simulink) , import it another tool such as Dymola and re-export it as CS-FMU with a variable step solver. However, this will be a different variable step solver than the original Simulink solver. )
