What does this mean? -- Simulation of default block diagram is not allowed

I want to use the App designer to run my Simulink modle, and I use "set_param( modlename,'SimulationCommand','start');", but I get this bug " Simulation of default block diagram is not allowed". What does this mean, and how can I solve it?

Hi Ying,

Maybe you can first try connecting to the model and then do the simulation. The code then would look like this:

set_param (model_name, 'SimulationCommand', 'connect'); 
set_param (gcs, 'SimulationCommand', 'start')
