Why Does Different Run Speed Have Different Output?

Hi, I am wondering why does different run time affect my overall throughput in the model?

With stop time set at 3600, if I run in 300 speed, I will get 30 throughput.

But when I set run speed to max, I can only get 19 throughput and all the items stack up in one of the queues?

Your issue looks like the statistical distribution of triangular not running speed.

The model stops when running NOT maximum speed.

The model has not any problem and the running speed.

My model does not stop as long as the run speed is not set too high (<500 all work fine).

Right now it stops at 3600 because I set it to stop

Your queues have logic in their Custom Draw trigger that open and close ports.

If the 3D view is closed, then the Custom Draw triggers won't be called at all. You shouldn't put model logic in the Custom Draw trigger; only draw code.

When you run the model fast, the 3D view draws less often so your code isn't being fired that opens and closes the ports.

Move your code into a trigger that fires at specific times rather than with the refresh rate of the window.
