Hello Matt,

If you say so concerning *.skp and *.idf, I guess I did a mess with the *.idf !

Please find it attached.

I noticed a couple of issues with the two 'underroof' zones on top of the building. First, make sure the surfaces are pointing out (the brighter/bolder surface pointing out); you implemenent this by right-clicking on the surface and going to 'Reverse Face'. Also, the adjacent wall and adjacent window shared by those two zones are not yet 'Adjacent' in TRNSYS3D, so please make sure that is changed.

Three questions now:

- How can I understand whether the *.idf is well done (just importing it in TRNSYS or also opening it as text?)?

Import the *.idf into TRNBuild first to see if there are any problems.

- Just to start correctly next time: it doesn’t make any sense, creating the building as *.skp and then drawing the TRNSYS zones (generating the *.idf) as “geometric carbon copy” of the *.skp geometry, right?

I would not bother with the *.skp geometry. I only work in the TRNSYS3D *.idf to avoid any problems.

- in zoning process, facing convex zones is really frequent (for example following the shape of flats within a multifamily house).

In order to create a detailed model following the apartments shapes (well zoned building, high number of zones, high simulation times), the only solution to represent correctly the “convex” apartment is to create 2 no convex zones separated with a full glazed, no resistance wall, setting then an high flow rate between the two zones?

Do you need to go into that much detail with your building to implement the detailed radiation mode? I believe now or in the next version that TRNBuild now allows some convex zones for the detailed radiation modes. Otherwise, your methodology sounds good as well.

Thanks a lot,

With best regards

Stefano

Hello Stefano,

I have never seen this particular error. To the best of your knowledge, were there any significant errors in your *.idf? You hopefully did not combine a *.skp file with your *.idf?

Best regards,

Matt Duffy

Dear all,

I am facing this problem with the TRNSYS3d plug in.

Is this the right place to communicate this, isn’t? Please find in the following the error description.

Thanks

Stefano
