Warning message "A possibile infinite loop has been detected" during ISV simulation

Creator

Hi all,

    During ISV simulation for a Cycle83 drilling, a warning was given as "A possible infinite loop has been detected". I can press the continue and the simulation would go on until end.

    After that I checked my program, nothing strange that I found. So what's the reason that might cause this warning?

    Attached are the programs that:

    Named "OK", no warning given.

    Named "Infinite loop", a warning was given during simulation.

 

 

    NX version 11.0.2.7. Thank you.

The incremental depth value of 0.03 mm is causing many loops through the cycle, so NX might have a check that avoids doing a specified number of loops.

Dear Stefan,
Thanks for your kindly reply.
Is there anywhere to modify the number of this loop check?

Sorry, I am not involved in CSE development, so I have no clue about the innards.

It was just a guess and might also depend on the NX release you are using.

Hi,

this message comes when 10.000 lines are execute without any time consumption. The counter will be resetted when the subprogram level changes.
This value cannot be customized.

One addition to Stefan and Thomas. That was defined as a saftey check to not run into NX none responsive state. At this point in time you can use "Don't display this message again" only. We are in the discussion to change the behavior or make it configurable.
