Model has disjoint parts in ConRad

[Hannah Denton]

 

I am trying to model a fly-by mullion in therm, but I keep getting the error “Model has disjoint parts in ConRad”. I have attached the file. Any help would be appreciated!

I will take a look at your file today.

Thank you so much!

Hannah, do you happen to remember how to solve this? I'm really at my wit's end.

Email me your file and I will take a look at it, and try to figure out what is wrong.

Robin, thank you so much for your reply!

John Neary is hoping I can get this one completed. Kind regards from him.

The idea here was to go through the FENBC steps of finding the U-value of a spandrel assembly, since NFRC does not define standards for accounting for back pans.

I suspect you might already be familiar, but the instructions are in a .zip file attached, in case you might be interested.

The issues come with importing a Glazing system that doesn't have a spacer or edge offsets, to simulate a uniform Center-of-Panel assembly with a back pan.

I've redone the file from scratch and it seemed to work :) --maybe in the first one, the edge BC's were somehow off or there were point issues, 

--but I've attached both the file that works and the one that doesn't run because “Model has disjoint parts in ConRad”.

My next steps would be to try and recreate this condition from a Payette article to see whether 15.6 Spandrel R-value with frame effect is possible, and whether the 3x glazing has anything to do with it.

Would be grateful for any input on this subject,
