Since the current version of FDS requires all surfaces to align to an axis, you must figure out a way to represent the vent in this way.
Some Ideas:
- Stair-step the vent, breaking it down into multiple sections (vents) that are controlled together and follow the slope of the roof line.
- Recess a horizontal vent into a cutout in the roof. Where the horizontal vent lies in the midpoint of where the sloped vent would be.
I am sure people could come up with other ideas, but these two come to my mind first.
