manual entry

Is it possible to generate a flow item manually, using e.g. a button in a GUI ?

yes it is. The easiest solution in my opinion would be to take a source and on reset and on the onexit trigger close the output. Then make the GUI with a button and on the onpress of that button, open the output of the source. Then 1 product is released, and the exit trigger makes sure that the output is closed again straight away, so only 1 product is generated. If you link the GUI to the source that makes it easier to refer to the source when opening the output.

Hope this helps,

Thank you Steven, seems to be easy.
Actually, the simulation halts when the source output is blocked, and my button has no action. Have I missed something ?
Sorry, I am just a beginner with Flexsim.

No that sounds correct. If there are no products entering your model, no events are created and nothing happens. But if you say that you are a beginner, this GUI stuff is quite complex so I have attached a small model that does exactly what I think that you want.
Load it, Reset it and run it. Nothing happens after 1 second. Than double click on the source and a gui with button comes up, when you press the button a product leaves the source. After 1 second a next product is available in the source and you can let it leave again.

I guess that your problem is, that you have no events in your model and therefore the model stops.

What you could do is have another Source and Sink in your model, just connected. Give this 'dummy' Source a high Arrival Time value and you have always an event.

Or you use a User Event at time (very high value) and repeat this event (also very high value) and you also always have an event.

I hope this is a correct answer, because I did not test my answer.

Good success
