Start Simulink Model with App Designer and run simultaneously

Hello,

I have an App which changes Values of Simulink blocks with the set_param command.

My problem is that I have to start the Simulink Model myself because I couldn't find any command with which I could start the simulation via Code AND run the App simultaneously.

With the sim command I was able to start the simulation but my App stopped executing until the Simulink Model stopped, so the sim command is not the right command for me.

I was able to find a workaround with the Callback ability of Simulink Blocks but it is not the perfect solution for me, because with this way I need to start the simulation and the App starts afterwards. The problem is, that my App is the "mother" of all the Functions and the simulation so I want to start the App first...

I hope You can help me to find a solution to my problem.

Thank You very much!

If you do it manually, what is the sequence? Run app, open the model, run simulation ???

Excactly. I have to run both manually.

Okay, then add code in your app to open and simulate the model. Then, just run the app.

Yes that‘s the plan but the problem is that I don‘t know which command I should use. Like I‘ve wrote, the sim command doesn‘t work for me because the program continues only after the Simulation stopped but the simulation time of my Simulink Model is infinite. So using the sim command is not the right choice for me.. Do you have an idea how to call a simulink model without getting stuck at one line?

f14;
set_param('f14','SimulationCommand','start');
set_param('f14','SimulationCommand','stop')
