Jet fan activation in tunnel
« on: April 23, 2020, 10:17:02 pm »

I am a new user of Pyrosim and I tried to follow the tutorial to set up jet fan.
However, after the simulation, I found that the jet fans did not activate.
May I know there is any problem of my input file?

It's the same answer as the question 2 below this one.

Set the Vent Endpoint on the Node Type to "in" and "out".

Tunnels are difficult to model and present special problems. Search "tunnels" in the FDS Users Guide.Also see Dan Swensons's posts on modelling jet fans.
