i have a building with holes representing large glass slider for nat vent purposes. i have checked the correct boxes etc but when i run the cfd boundary conditions after the simulation the results do not show any airflow across the holes.
most of the building is mechanical but the natural vent is selected for block 1 zone 3 and block 3 zone 1.
definately. i ran the simulation. checked the air in and air out in the graphical display and that looks ok, but i cannot tell from the graphic if it is through window or hole.
when i import to cfd boudary conditions there is air in and air out but it is only through the windows. the holes show 0 airflow.
i have checked marked natural ventilation for these zones. nat vent is on calculated in options tab.
in output i have marked the options indicated in help and videos.
