radiance parameters to get rid of blotching. To add another level of complexity to my problem, I am running simulations with a translucent material with the following properties: void trans testTrans
0
0
7 0.478 0.478 0.478 0.000 0.010 0.178 0.635
I have had no issues with the renderings when I use clear glazing, as seen on this image:
However the blotching-issue becomes very noticeable when I introduce translucent glazing into the scene:
For the two above cases I used the following parameters:
_av_ is set to 0
xScale is set to 2
_ab_ is set to 6
_dc_ is set to 0.5
_aa_ is set to 0.2
_ad_ is set to 2048
_st_ is set to 0.5
yScale is set to 2
_ps_ is set to 4
_ar_ is set to 64
_as_ is set to 2048
_ds_ is set to 0.25
_pt_ is set to 0.1
_dr_ is set to 1
_pj_ is set to 0.9
_dp_ is set to 256
_dt_ is set to 0.25
_lr_ is set to 6
_dj_ is set to 0.5
_lw_ is set to 0.01
I ran another test with increased Radiance parameters and got the following output:
with the following parameters:
_av_ is set to 0
xScale is set to 6
_ab_ is set to 6
_dc_ is set to 0.75
_aa_ is set to 0.1
_ad_ is set to 4096
_st_ is set to 0.15
yScale is set to 6
_ps_ is set to 2
_ar_ is set to 128
_as_ is set to 4096
_ds_ is set to 0.05
_pt_ is set to 0.05
_dr_ is set to 3
_pj_ is set to 0.9
_dp_ is set to 512
_dt_ is set to 0.15
_lr_ is set to 8
_dj_ is set to 0.7
_lw_ is set to 0.005
Although the second blotching case is much better than the first, it is still very bad for hours when the sun is lower in the sky. The above images are rendered for a clear sky at 18:00 in Germany in a West-facing room.
Sorry for the long post! Can someone help? Kind regards, Örn

nside the zone. I would move your comfort evaluation surface to be 1 meter off the ground in order to be representative of typical human height.
Also, you did not intersect the ground with the rest of the zone geometry, resulting in an incorrect energy simulation. After intersection, you also get one surface of the ground zone that is not inside any buildings. I fixed these two things in the attached file ad it works:
I would also recommend breaking the top surface of the ground up into sub-surfaces so that you can capture the variation in ground surface temperature that happens across the outdoors. Second, I would recommend putting some windows on your buildings as the exterior surface temperature of windows can be very different than that of opaque surfaces. Finally, you should keep in mind that the outdoor maps are assuming a very basic outdoor wind profile by default and, to accurately understand outdoor comfort, you really should be incorporating wind patterns after running a CFD. This discussion has some information about importing CFD from other programs to GH:

The issue is that downloaded 'pluto_20v2.csv' file is enormous - 290MB.
I tried to delete about 95% of it, and approximately use only the first 5%.
I hope the definition provides some insight.If not, let us know.I couldn't upload the files for some reason. They are here:https://www.dropbox.com/s/grxuta8v8x18u70/mapData.gh?dl=0https://www.dropbox.com/s/5igqsdnryz9df2q/pluto_20v2%20first%205perc.zip?dl=0…

s feature generally prevents us from doing but in this case I'm 95% sure the loop won't brake GH as the Data Rec should actively try to prevent this from happening.
So I'd like to ask you if there's any way to bypass the cyclical data stream detection? I believe what I'm looking for is a way to send a value from an output to another input without having a "wired" connection between those two components. Any ideas on how to achieve this? Scripting?
Thanks.
PS: Unfortunately I wasn't able to simplify my current definition to a point where it could be used as an example, so please treat this more as an generic question.

2) The Curvature "flips"
The curvature graph component creates exactly what I need, but unfortunately it only visualizes the new curve (lets call this c1), without actually making it usable. If it were usable, I could just test for curve-curve intersections, and discontinuities in (c1). I have more or less replicated the behavior of the curvature graph component, except that my imitation is too smooth (lets call my imitation curve c2). I attached two images to demonstrate what I mean.
Is there a way to get exactly what the Curvature graph makes? How is it creating c1? Is it just a much larger sampling of points? Or does it somehow operate (calculus?) on the underlying formula of the curve (c0)?
Any guidance is hugely appreciated. …

the attached image is lucid.
Anyways, I have been able to sync up the various lines so that the correct ones can come together and create a new polygon through the edge surface command. The problem is, the way I have set it up means I can only get one of them to produce. I could re-create the piece 'n' times and adjust every single one accordingly to get the pieces, but I'm assuming that's not what I should be doing. Is there a way to make these come out with the 8 planar surfaces according to the subdivision I'm looking for? I feel like it has something to do with lists/series, but I'm not exactly sure what...
Files attached.
Much appreciated.
