[TRNSYS-users] Error creating Large Opening in TRNFLOW

[Yose Wandy]

Hi again,

 

I somehow manage to overcome the problem by adding a crack into the zone
from an external node.

Weirdly though it only show 0 massflow from/to each connected airnodes,
although I have a ventilation system in the simulation model and the plot
shows the effect of the ventilation system in each airnode.

 

Best regards,

Yose Wandy

Betreff: [TRNSYS-users] Error creating Large Opening in TRNFLOW

 

Hi TRNSYS-Experts,

 

I tried to connect two airnodes within a zone in order to have the airflow
between the airnodes calculated (splitting a room into 2 airnodes) and came
across an Error saying that there aren’t any adjacent wall or coupling. .
The “virtual surface” for both zones was created as usual in Trnsys3d and
the airnodes were connected into a mutual zone in TRNbuild.

*Refer to image 1.

 

So I activated the “Upper” coupling with 0 kg/h massflow  of both airnodes
to each other and came across another error saying that the airlink network
isn’t properly connected.

*refer to image 2

 

Has anybody encountered the same problem? Or did I miss any step in order to
simulate an opening in trnflow? I already dig in the mailing list archive
and found nothing, it would be nice if somebody can help.

 

Thanks in advance.

 

Best regards,
