Re: [TRNSYS-users] TRNFOW changes airnode to constant pressure node

Dear Annamaria,
you have to rename all the thermal zone nodes beginning with F2_ .
As F2_ is the keyword for a flow controller link type (all flow controller links begin with F2_ ) TRNBUILD cannot handle this name.

In any case you also have to adjust your network: Large Openings have to have the FROM and the TO - node at the same height.

Best regards,

Dear Annamaria,

What are the names of the thermal airnodes/zones?

Do the name of the modified airnode has “PA” in the name?

Can you send me the b17 and the link ID where this happens.

Best regards,

Transsolar Software Team

Betreff: [TRNSYS-users] TRNFOW changes airnode to constant pressure node

Dear TRNSYS users,

I am using TRNFLOW to model airflows between zones. I have horizontal openings to connect ground floor zones to first floor zones so I set the own height factor of the large opening to 0.

When I save the bui file, the links to the thermal airnode are replaced with constant pressure nodes, with 0 Pa pressure and the Trnbuild stops working.

Why is this happening?

Thanks in advance,

Annamaria
