Hello, I'm doing a lot of simulations on simulink, and i want to stop and skip the simulations when there is a warning. Is there a way to do it ?
This is the code i tried for the moment, but it doesn't skip the simulation, which takes a lot of time.
for p = 600 : 25 : 1600
for d = 250 : 10 : 300
for i = 0 : 2 : 20
try
Kp = p*eye(6);
Kd = d*eye(6);
Ki = i*eye(6);
sim controle_simple
catch ME
continue
end
% some code to save data
end
end
end

Hi,
The commands try/catch are used for executing statements and catch errors messages not warning messages.
Since getting a warining can still allow you to run the model, you have to catch the specific warning message and include a 'break' in your for-loop.
A way to catch the warning message is by looking at the following variable when running a model:
ans.SimulationMetadata.ExecutionInfo.WarningDiagnostics.Diagnostic.identifier
For example, when a model has a unconnected outport, the value of this variable is
Simulink:Engine:InputNotConnected
Then, your code will include something like:
if (strcmp(ans.SimulationMetadata.ExecutionInfo.WarningDiagnostics.Diagnostic.identifier,'Simulink:Engine:InputNotConnected'))
break
end
Hope it helps!
