LBT energy simulation problem

Hello everyone,
I have created a simple model of a room that has a wind catcher attached to one of its wall. I tried to run energy simulation but I got error. Anyone could help what is the problem?
I want that the wind to be circulated like the picture below. Please How can I do that?

After reading other people examples I realized that in order to have an opening in the wall like a chimney, I have to add a window then set it as constant open. I did that and update my work, but I am not sure whether it’s right or not. Can anyone advise me please? and if I need to add other factors to get an accurate result.
