natural ventilation error

jlong · Posts: 3

Hi all,

In my simulation i have selected natural ventilation under the model data tab to 'calculated'. i would like to reduce the percentage of glazing which is openable so as i can find out at which stage the room will over heat.
upon simulating i get the following error 'get airflow network input'

does anyone have any suggestions as to what i might be missing out on?

EDIT:

i have attached an image of a window and also the dsb file that i am trying to simulate. the lower six panes will be openable and the top three will be fixed.

i want to change the openings of the window i.e. top three open + bottom three open to see if the room will have stack effect ventilation which will help to cool down the south facing room.

Hello James,

Your model run well with my DB (1.6) so you may update your own to solve the problem.

I stay tuned if you meet problem again.
