Ignore unavailable outputport

Hello everybody,

I want to ignore if an output-queue is unavailable (because its maximum content is reached), move a FlowItem anyways and print a error message to the output console instead of stopping the simulation.

Printing the error code with a little bit of information where, when and with which FlowItem the error occurred is not a problem.

But when I use the moveobject command, the FlowItems which I moved with the command remains in the queue and don't get processed after all the regular FlowItems have been processed.

I assume this is because there was no real incoming event in the queue, when I moved the FlowItem by command.

How can I work around this problem?

Thank you guys in advance!
Jens

Flexsim v5.1.2

What about another solution:

- set maximum content to a high value
- set the wanted maximum in a label
- in onentry you can generate a message, if the content is bigger than the value in the label

Greetings

Why don't have 1 overrun queue. So if it can't go to the normal send it to the overrun queue. If necessary you can connect this queue to the normal queues again so that it continues with these items when there is space again.

Thanks for the idea,would definitely work.
But before I change everything I'm trying out to fiddle around with my current routine.

Is there some additional documentation to the opavailable() command? I cannot find something in the commands list.

In case of using your current solution, have you tried to use "releaseitem" on the item that is done with moveobject?

And where have you found the opavailable command?

@ Steven: I did some simple sample models and I think releaseitem in combination with moveobject will also do the trick. I give it a shot and I think I try both options.

I found the opavailable command when I looked through some of the picklist options and tried to find a solution for my problem. (I.e. Send To Port : Shortest Queue if Available)

// and I didn't find the thread Jason mentioned because I misspelled available .. facepalm - well it's friday

Ok, I did the method using labels. Now I all errors get printed in the Output Console (I reduced the queue maxcontents to 5, so I can check if everything works).

But when I stop the model or want to reset it, Flexsim crashed and closes without any comment.

Is there a logfile or something where I can see what caused Flexim to close?

Open the system console and see what it writes there. Hopefully you can see something before Flexsim closes.
