d 'outletBoundary' components in which the 'temperatures_' represents?
The 2nd ques is more about thinking how to achieve more potentials by BF. I am doing a project that is trying to implement the construction method of 'DOUBLE-GLAZED' facade, which will conduct air flow inside a building and save more energy. Since I also use LB&HB for time-based analyses, so I`m wondering if BF could use time-based-srf-temperature to achieve a more dynamic simulation in a day, let`s say, a hot summer day, 10:00 to 16:00?
And the last what is the definition of these recipes(pic no.2)? what do they mean?
Thanks in advance for the helps!
Best wishes,

rasshopper and reinstall it every time because I've seen this problem before in forums but no one ever came up with a fix. Edit:Another weird leak is when I close rhino and grasshopper now even that I had stable low memory usage before closing. Process Rhino.exe is till running and climbing in memory and reached 97% even the program is shut down.Edit2: My gut feeling is that when a component reaches certain branch/item number it starts leaking memory. And specifically recent file/ MRU list is doing the leak…

I was trying to update the old VB component to my new 0.9.0006 GH release, copying and pasting, but as I'm new in this scripting world I'm unable to solve the error bounced at the line 97 when I link the surface component.
Any suggestion??
thanks in advance!!

see, the results indicated in the error for pressure are, well I don't think I know the name for those numbers. But values of XE+118 mean the simulation was diverging. I would recommend you to update BF, if you haven't already, re-run the case and test after.
Also, you can post your mesh settings here. Most other times is mesh quality causing this.

he potential of BF to assess such cases. In your search, try and be specific on what you want, cause validation can focus on codes (i.e software environments like OF and Fluent), solvers (e.g. RNG vs kEpsilon vs kOmega, etc.), meshers, and so many more. Additionally, I'm sure there's a lot of CFD studies of Atrium spaces.
Myself, I haven't been involved in any validation studies as I have always used CFD on the practical side of things. Therefore, I always trusted OF since it has been heavily validated over the years.
The beauty of BF, or at least its end goal, is that you can easily test design alternatives directly from a friendlier and possibly better-known environment of Rhino3D.
I would suggest therefore to just try things out. Design your geometry, in this case the atrium, in Rhino. Decide which are the parameters that you wish to investigate and incorporate those to a GH definition that produces different design alternatives for the range of those parameters (i.e. your parametric model). Then run the cases through BF. There's a couple of examples that come with BF and a few others users are providing either here or on github.
I'm afraid trial and error is painful with CFD but it's the best way forward. Also, I suggest you bookmark cfd-online.com and skim through everything in there. Most if not all of what we are discussing has been discussed there.
Good luck!
Kind regards,
Theodore.

urs x 365 days ), and with modulus in the screenshot above, i could manage to do for every hour. but sometimes in my definition, i have a range from 1 to 35040, which is 365 x 24 x 4 ( 4 here defines every 15 minutes), on other word, when the number is one, then i have 01:00 O'Clock, when the number is 2 then i have 01:15 O'clock, when the number is 3 then i have 01:30 O'Clock...etc , so when the number is 97, which is the next day ( and after the number 96 which is equal 24 hours x 4), then I should have again 01:00 O'Clock.
I hope my idea is clear, thanks in advance!
