How to export models from Ansys Fluent, Comsol Multiphysics, GT AutoLion & Siemens Amesim to use in MATLAB/Simulink?

I would like to know about the requirement of toolboxes to use the export models from the above mentioned softwares in MATLAB/Simulink.

Also could you please let me know the file formats of the export models that will be generated from the above mentioned softwares. Also how compatible are these softwares' export models to be used in MATLAB/Simulink with the required toolboxes.

This is in reference to the Electrochemical models developed in the above mentioned softwares.

Hi Sree,

I see that you are looking for ways to export models from various industry standard tools into MATLAB/Simulink.

The FMU standard (Functional Mock-up Interface, FMI) is the most robust, widely supported, and recommended method for exchanging dynamic models between simulation tools and MATLAB/Simulink. All the mentioned software platforms (Ansys Fluent, COMSOL, GT-AutoLion, Siemens Amesim) support FMU export.

Therefore, to import your models and the information into MATLAB/Simulink, you can export them as an FMU file (.fmu). You can then choose Co-Simulation (FMU-CS) or Model Exchange (FMU-ME) depending on your workflow.

Use the FMU Import block in Simulink to bring the .fmu file into your Simulink model. You can refer the following documentation for the same:

FMU: https://www.mathworks.com/help/simulink/ref_extras/fmu.html

Import FMU: https://www.mathworks.com/help/simulink/ug/work-with-fmi-in-simulink.html

While this is the industry standard and the recommended way, you can also look at exporting the information in other formats such as CSV or MAT Files.

Hope this helps!

Hi Amish,

Thank you for the response.

Could you also elaborate if we can change the parameters of the model in the mentioned software platforms also in the Simulink environment. How flexible is this method to calibrate the model in the Simulink environment?
