Error - The occupants appear to be stuck
« on: October 27, 2014, 05:50:23 am »


I have got an error message - "The occupants appear to be stuck. Simulation paused"

Could someone kindly advise me to resolve the issue

Thank you!

The first step is to figure out which occupants are stuck. You can do this by viewing the simulation results that have been produced so far. Then you have to figure out why. You can also work with Thunderhead by emailing your model to

Here are some common causes:

- A large occupant cannot fit through a door needed to make it to the exit. In this case the occupant will remain at that initial position because a path could never be found.

- Two or more occupants are trying to exit an isle in opposite directions and they can't pass through one another.

- Sometimes occupants get jammed up moving through small spaces. We pursue these bugs pretty aggressively and post fixes. If you run in to this sort of problem, please email support and make sure you are running the latest Pathfinder.
