Is there a way to abort Simulink simulation programatically if it takes a long time?

I have a model that, depending on some variable values sometimes runs very slowly. Typically I try out many different variable values in a loop, i.e. I start the simulation from a MATLAB script. Is there a way to abort the simulation without breaking the loop if the simulation takes too long?

[Rob Graessle]

Walter is correct about using a timer object that is configured to fire at the end of the wait period. In the timer callback you can use the following command to stop the simulation:

set_param('ModelName', 'SimulationCommand', 'stop')

where ModelName is the name of the model you are simulating.

Thanks, it worked fine.

The way I solved was basically like this.

myTimer = timer('StartDelay',10, 'TimerFcn','set_param(''ModelName'',''SimulationCommand'',''stop'')');
for KpGain = 1:10
  start(myTimer);
  sim('ModelName');
  stop(myTimer);
end
delete(myTimer);

I guess that in a parfor loop you would have to be a little more careful of having different timers for different workers, right?

In the MATLAB routine you could start a timer that would fire at the end of your wait. In the timer callback, you would instruct the simulation to stop.

I do not know the details at all, as I have not used simulink. It might involve setting a parameter and using a STOP block; see a recent cssm post

There appears to be some other useful information in this cssm post
