Jet Fan in FDS
I am trying to teach myself how to use fds using the manual - which I am finding quite difficult however am enjoying.

I have constructed a simple box of 32m x 16m x 4.8m - added heat detectors and door openings, extract fans and inserted a fire to simulate an enclosed car park.

I am trying to insert a jet impulse fan on the ceiling with no success as I have the code written incorrectly (as it tells me there is a problem with the vent)

Can anyone assist?

You could try with pyrosim. It's very helpful for FDS.
