Hello Amit,
When executing a Simulink model via command, the “pause”, “resume”, and “stop” options become inactive within Simulink(when using MATLAB R2017a). To address this, I suggest updating MATLAB to the latest version, where these buttons remain active.
Furthermore, to manage Simulink operations through commands, Simulink does offer specific commands for “pause”, “resume”, and “stop” that can be used to control the model programmatically.
Here is the documentation on commands for "Controlling Simulink Programmatically", which are applicable for use within App Designer:
https://www.mathworks.com/help/releases/R2017a/simulink/ug/control-simulations-programmatically.html .
I have replicated the issue using MATLAB R2017a, and in my experience, the code within the “StopFcn” did execute. I recommend reviewing the code in your “StopFcn” for any potential errors.
Additionally, in my tests, the Simulink progress bar was visible when the model was executed using the “set_param” command. If you continue to encounter issues, please examine your Simulink model for errors. Should the problem persist, here is a link to a MATLAB Answer that provides a suitable workaround using “Simulink Waitbar”, which can be customized to act like the original progress bar: https://www.mathworks.com/matlabcentral/answers/168954-view-progress-of-simulation-when-using-sim-command .
