Thread-topic: [TRNSYS-users] Error generating VFM file for a convex zone

Dear Misbah,

your zone A is not actually convex, you can see our Trnsys3d tutorial for more explanation on this: https://www.trnsys.de/static/b2ad8081a2b12168fb8d075d99b71392/T3d_tutorial.pdf

TRNBuild currently only offers the 3D-geometry mode with full functionality for convex zone geometries, so this is the option in the interface that is marked. It does not tell you if your zone is actually convex or not.

Best regards,

Christina

Betreff: [TRNSYS-users] Error generating VFM file for a convex zone

Dear TRNSYS users,

I created a multizone building with google sketch-up and successfully imported it to TRNBUild with no error. In the geometry mode (Trnbuild.png), both zones (skp.png) are convex . However, I could only generate a VFM file for Zone B. I am interested in the detailed model for both zones which is based on view factors for the longwave radiation exchange within the zone. I know that to use the detailed model, the zone has to be convex and closed. So if TRNbuild automatically assigned zone A as convex, why can't I generate a VFM file for zone A?

Kindly help me with this.

Please find attached Trnbuild.png and Skp.png for your reference.

Thank you.

Misbah.
