Hi everyone,

I got an error "DUCTNODE must lie with a single pressure zone. Node: (Node_ID)..." and then "FDS was improperly set-up - FDS stopped". I do not prescribe any pressure zone in my input file. I am using FDS 6.7.9. Has anyone ran into similar issue and know how to fix this issue?

Thank you!

Chi

FDS .6.7.9 will automatically look for pressure zones. Check your VENT definition for that node and make sure you haven't put a wall through it such that it has wound up in two zones. If after doing this you still have an issue simplify your input as much as possible while still seeing the error and post to the issue tracker.

Thank you for your suggestion, Jason. It solved my problem. There was a couple small obstructions created by geometry importing she grid snapping that got in the way.

Have a great weekend!
