How to find where goes wrong quickly

In running flexsim model,if it stopped after you click "run",how to find where goes wrong quickly(which model setting need to be revised).Since there were so many objects,it is hard to check the settings,codes and etc. object by object.

The biggest thing is probably make sure it's repeatable and and find the time when it occurs. If the model has just 'stopped' then the last event time is already shown on the clock. Then step through the model just prior to that time, looking at the debugger event list to identify the exact event where things go wrong.

Another general tip is to step through all non-trivial code you write with the debugger to verify it as correct. If you've got code repeated in many places through the model you might want to consider putting it into a user command that you call from many places - that will make it easier to manage and prevent errors slipping in.

You can also turn on the Event Log and see what event happened right before something went wrong.

If you have an exception in your code, there will be a line in the event log showing that exception. The event immediately above the exception line is the code that threw the exception.
