Export Model to Simulation App - Parameters Selection

Dear Sir or Madam,

I am developing a Simulink model I want to export as a Simulation App in order to further create a Standalone App. I observe that the exportation menu does not provide the option to define which model parameters are exportable (for instance, FMU exportation does provide this option).

I do not want all the model parameters to be exported, just a few ones; and I would like to be able to choose them.

Is there any option to solve this issue?

Best regards,

Hi Victor,

I understand that you want to export a Simulink model as a Simulation App with only select parameters. As per my knowledge there is no way currently to achieve this. However, the following workaround is possible:

1) Create a Simulink model.

2) Export the model as a Simulation App.

3) Navigate to the created directory "/assets/data". The model data is stored in this directory in "modelData.mat".

4) The tunable parameters are stored as a struct named "modelData.tunableVariables" in "modelData.mat" with fields "QualifiedName", "Value" and "Workspace".

5) Delete the undesired parameters. For example, the commands to delete a parameter named "paramName" is:

load('modelData.mat'); % ensure that "/assets/data" is added to MATLAB path before loading
modelData.tunableVariables(indexOfParamName) = []; % indexOfParamName is the index of paramName in the tunableVariables struct

6) Save changes to "modelData.mat" using the command:

save('modelData.mat','-append');

I hope this helps!
