setVariable in simscape model through SimulationInput object( MATLAB web app server)

Hi everyone,

I am trying to set the value of a parameter that stays inside of a simscape block, using a web app aplication that was deployed on the server using MATLAB web app server.

The documentation says that the following Simulink functions and classes are deployable:

Functions:

• sim
• start_simulink

Classes:

• Simulink.SimulationInput and its method setVariable
• Simulink.SimulationOutput
• Simulink.SimulationData.Dataset

I am using setVariable which allow me to set variables for a simulation through SimulationInput object.

SimInp = SimInp.setVariable('Tetha',app.tethaSpinner.Value);

In this way, I can modify certain parameters of the model but when the parameter is inside a Simscape block (elecrical , multibody, etc...) I am not able to modify the parameter anymore.

This problem only happens when I have to configure the application for deployment on the server using:

SimInput=Simulink.SimulationInput('SpringDamper');

SimInput=simulink.compiler.configureForDeployment(SimInput)

So, I was wondering if the problem is that the method SetVariable does not works with Simscape's blocks but only with Simulink Classic blocks.

Any suggestion would be great

Thank you

I solved my problem setting the simscape variables at Run-time variables, in this way when the parameters of a Simscape block are changed there is no need to regenerate the C code therefore the deployment of the app will succeed.
