Add a warning for boundary conditions (nat. vent)
We should/could add a warning for deep floor plan simulations using natural ventilation to flag the 5.5m depth limitation (or 2.5x room height) as mentioned in our paper. I suggest something like: if (width or length > 5.5m) or (width > 2.5x height) or (length > 2.5x height) then give a warning Suggested warning text: The room dimensions you have entered indicate there may be a significant distance between the windows and the opposite edges of the volume. Natural ventilation is typically effective for room depths up to 5.5m away from the windows, or a depth of 2.5x the room height. If these conditions are not met, your simulation may produce artificially low risk results.
