flectance and use .2 as default. You can use ShadingProperty:Reflectance to change the default value. We don't support this in Honeybee interface right now but you can create the objects and add them to your energy model using additionalStrings_ input.
I put a simple example together were I change the reflection for shading surfaces to .5 for unglazed part of shading and portion and .7 for glazed part. I also set the percentage of glazing to 50% of the surface area.
I didn't put any input checks. Make sure to read the documentation to put valid input values for energyplus otherwise the energyplus simulation will fail. I also assumed that all the shading surfaces (context) will be planar surfaces.
Keep in mind that it will only effect the results if you are using one of the solar distributions with reflections. Honeybee is using FullInteriorAndExteriorWithReflections by default so you should be fine if you're using the default settings.
Hope it helps,

look like this. Where First Character of first Row is X coordinate and next character of same first row is telling No of times X coordinate is repeating.
Then next rows from 2 to 7 (6 steps) are Y, Z coordinate...like that it is going.

er into the t input so that the two points were constantly shifting up the line. Is there a way of creating a normal or tangent that keeps the plane oriented in one direction?
-
The file is included, bright blue panel is where the plane function is. The rest of the code is rotating 7 points in a helix about the line, while projecting to the moving plane. The unexpected rotations are giving my helix tight turning points that are messing with the aesthetic!

ow the steps of the successful run when step 1.2 is bypassed (note that the and OpenFOAM session is open in the background while running the Butterfly demo file):
1. create wind tunnel, and use different parameters of (4,4) for _globalRefLevel_ as suggested by Theodoro in this post
2. run blockMesh:
3. run snappyHexMesh:
4. run checkMesh:
5. connect the case from checkMesh to simpleFOAM and run the simulation:
6. the simulation converged at 1865 iteration, but the results visualization part has some problem:
7. so I revised this part according to suggestions from Hagit:
8. and the results can be visualized for P and U values:
The GH file used for the successful run shown above is attached here.
Now, the following is the error I got when the case from the update fvScheme component is used for simpleFOAM simulation:
the warning message on the simpleFOAM component is:

The error message from the readMe! output node is attached below as a text file.
Hope you can kindly advise what the important steps or parameters I might have missed here. I assume it might be related to OpenFOAM rather than with the Butterfly workflow...
Thank you very much!

d having the entire surface adjust while maintaining equilateral triangles. The closest solutions I've come across are the equilateralize and shell and plate examples for Kangaroo (images below), but I don't think the definition in the equilateralize demo will work because I don't always want 6 triangles around each vertex (I want a range from 4 to 7.) The shell and plate example seems more promising, but when I open it in rhino/GH it says the C# component is old, and the code is missing. Also, the shapes I'm trying to model are much less spherical than the mesh in the demo, so I'm not sure if that method will work anyway. I'm also posting an image of some physical models that show what I'm going for.
Any advice would be much appreciated!

l design.
2/ Optimization
2.1/ in prefabrication
2.2/ combinatorial
2.3/ approach comparisons (i.e. deterministic vs stochastic)
2.4/ share your research
2.5/ ... etc. the list goes on and on
3/ Share you design rationale and how computation fits in
4/ Need help with this problem...
5/ Challenges and workshops announcements
6/ CD News
7/ Share computational design projects under construction or built (akin to skyscrapercity)
8/ and so many other categories and sub-categories...
Just my first thoughts. That breakdown in optimization is just an example. Maybe 'sections' is an old-school way of seeing things, I just wanted to share some thoughts on the kind of content I look forward to seeing. It can be pragmatic topics, but also theoretical, and allow folks to share their projects and research. Some categories are specific, others broad. I suppose I'm interested in community building with regards to computational design. I think SmartGeometry attempted to accomplish this at some point in the past, to some degree. However their focus appears to be in the workshops and challenges.
I recall the silly flame wars that the CG industry had 20 years ago (lame). I'd avoid that, even if it meant forbidding the mention of any specific software in certain areas or in the entire forum. Which would be tricky, but the endless flame wars and silly comparisons were such a waste of everyone's time in CG.
Without dwelling on this too much yet, I think that the software specific questions belong in software specific forums. If we already had a common language for computational design, you'd just need to add the right description as a meta-tag to any Dynamo or Grasshopper forum post, and you'd be able to find analogous solutions in either forum effortlessly, right?
The Dynamo and Grasshopper forums lack design-centric content. The emphasis is generally on the tools and workflow. Computational design is hybrid in essence, it involves both design and computer programming (be it visual or textual). We could really use a forum for knowledge exchange where the expectation is that both are discussed with equal status.
I disagree that such a forum ought to exclude professional programmers. It should include professional programmers whom have an interest in design, and also include professional designers whom have an interest in computer programming, and everyone in between, and enthusiasts, and artists whom are curious about algorithms as a creative medium, and academics, and students, and etc etc. As long as there is rich content and activity on design as well, not only the computational bit, then the crowd will be diverse and we'll all have more to learn from one another.…
you post a screenshot of what the message coming from its readMe! output looks like?2) Close your Grasshopper and Rhino.3) Download "Revo Uninstaller Pro" from here. It is free for first 30 days, which is what we need.4) Right click on the RevoUninProSetup.exe and check if the file is blocked. If it is, unblock it.5) Run the RevoUninProSetup.exe file and install "Revo Uninstaller Pro".6) Uninstall "MapWinGIS" with "Revo Uninstaller Pro". It is important that "Revo Uninstaller Pro" deletes not only files from MapWinGIS installation folder, but also all other leftovers (as registry inputs). Here is a small tutorial on how to do that. Watch it from 6:10 till the end.7) Restart your PC8) When your Windows boots up, make sure that you are logged in as Administrator!9) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".10) Turn off your Windows Firewall.11) Then turn off your custom Firewall (in case you have another one, besides standard Windows Firewall).12) Completely turn off your Antivirus.13) Download again the MapWinGIS-only-v4.9.4.2-x64.exe.exe file from here.14) Right click on the MapWinGIS-only-v4.9.4.2-x64.exe file and see if it is blocked. If it is, unblock it.15) Right click on MapWinGIS-only-v4.9.4.2-x64.exe file and choose: "Run as"... Administrator.16) One the installation preparation steps start, choose "Full installation". Wait for the MapWinGIS installation to finish.17) Right-click on "Rhino 5" icon and then choose: "Run as administrator".18) Open the the ironpython_admin.gh file again, and again post a screenshot of the message coming from its readMe! output.19) Drop the "Gismo Gismo" component to Grasshopper canvas. Post a screenshot of the message coming out from its readMe! output.
So we will need in total three screenshots of the readMe! output messages.
Thank you once again for being patient, and sorry for the large number of steps.…

ice 2007. So I went out and bought Office 2010, and all my Excel interopservices vb.net scripts are now failing. They had all worked fine before...now when I execute they give the following error:
error: Invalid class string (Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING)) (line: 0)
Here's the boiled down script:
If activate = True Then
Dim oldCI As System.Globalization.CultureInfo = system.Threading.Thread.CurrentThread.CurrentCulture
System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("en-US")
Dim xlApp As Object
xlApp = System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application")
Dim xlSheet As Object
xlSheet = xlApp.ActiveSheet
xlSheet.Range("A1").Value = "test"
End If
The failure happens with the addition of the InteropServices line. I'm mid-project right now, and it's pretty critical that I regain the ability to go back and forth from GH to Excel in the scripting environment...does anyone know if I need to deactivate any security options in Windows, make sure any dll's are properly installed...anything? I've tried all of the other Excel components that various users here have already been generous enough to share (my scripts are all based on them). I can't seem to find any documentation (that I understand) about this particular error message, or how to fix it. Really could use a little help!
thanks in advance,
Dave…

ehow acquire different settings/are calculated differently. Appears at random “rows” of points, sometimes it all works fine, so I need to do a series for the error to show. See images below.
In the Ladybug fly run the VT of the window changes.
It’s taken me a day and a half to track this error down. Phew.
I get the same error on two different comps.
What is causing this? Does anyone get the same error? Images below created with RADquality set to 2, and 7 cores. Fiddling with Radsettings dont help, I think, except error goes away with very low ab.
