Create Simscape protected or pre-compiled model for users who don't have Simscape licenses

I created a Simulink model (Model.slx) containing Simscape blocs. I need to share with some people for compilation purposes who does not have Simscape licenses.

I could create a script to protect the Simulink model:

Simulink.ModelReference.protect('Model.slx', ...
    'Path', 'C:\MyFolder', ...
    'Report', true, ...
    'Mode', 'CodeGeneration', ...
    'CodeInterface', 'Top model', ...
    'OutputFormat', 'CompiledBinaries');

On my laptop with Simscape licenses, I am able to compile the Simulink (CodeToCompile.slx) that contains the protected model, and the code works as expected. But people who does not have Simscape licenses are not able to compile the code. I tried to compile the Simulink model into C code, but that created mainy .c files, so I am not confident in how to import the compiled model into CodeToCompile.slx.

Am I missing an option into the Simulink.ModelReference.protect function ? Should I go with the generated C code, and add each .c and .h to the Custom Codes of CodeToCompile.slx ? Are there any other way to create a model from Model.slx that people who don't have Simscape licences can compile ?

Many thanks for your help !

Hi, Valentin,

I understand you want to share a Simulink model containing Simscape blocks with colleagues who do not have a Simscape license.

You can refer this answer posted by MathWorks staff on similar issue:

How to run a model including Simscape blocks in a Simulink environment without a Simscape license? - MATLAB Answers - MATLAB Central

Hope this helps.

Hi Ayush,

Thank you for your reply !

I have already seen that discussion that looks like very close to my topic. As I said I already tried protected model. With the default settings, the protected model is dedicated for simulation. But people I need to share the model with (no Simscape license for them) are looking to compile the whole code that will include the model. Here is a scheme describing maybe better what I am looking for:

Instead of using the UI window to generate the protected model, I used the script I have given in my original question. I could change the protected model settings for code generation, I am now able to compile the CodeToCompile.slx, but people who don't have Simscape licenses they still can't. I may use wrong settings.

The other solution, compiling the Simscape model to an executable, could be interesting for non-Simscape users. But tell me if I am wrong, they could not import the .exe into the Simulink they would like to compile, and interact with inputs/outputs. They will ?

Hope it is more clear for you to understand what I am looking for, and make it easier to find a solution.

I don't think Model reference, protected or not, will allow the user to run without Simscape.

Do you have the licenses needed to create a standalone FMU? You can bring that into a Simulink for a non-Simscape user, and that won't require Simscape license.
