Error message relating to fire
« on: March 12, 2013, 11:08:13 pm »

Hi everyone,

I am trying to run my model and am getting an error message. I have created the fire using the model in the
example guide but when i run on FDS it states ' Vent1 must be attached to an obstacle'. I have located the
vent on the floor slap but am stcu as to how to solve this. any help would be appreciated.

Double-check the coordinates of your vent. If it is a horizontal plane, then both Z-values have to be the same. Ensure that they are the same as the Z-max value of the slab. (If that doesn't work, I suggest you post your file.)
