Hello everyone,
actually i want to simulate a greenhouse in which roof windows and side windows were used for natural ventilation. so for this purpose i made links of large opening in TRNFLOW one option in main window of TRNFlow is creating problem "own height factor" for side window will be 1 thats okk and by changing opening factor of window i can get results as i need. but when i try to simulate roof window ("own height factor" should be 0 for this) with different opening factors of window i got same result no effect of different openings on inside temp. my question is, can i simulate roof opening correctly by using TRNFLOW as i read on TRNFLOW manual page 20 about large opening that calculation of this is not physically correct.
