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.…
d. If what you say is correct about the small difference between the global horizontal and direct/diffuse calculations in the MENEX model, than the discrepancy likely has more to do with the difference between the approximation of human geometry in the MENEX model (plane or cylinder) and the human geometry approximation in the SolarCal model (some coefficients derived from radiation studies of mannequins). I noticed some fairly large differences between using a suggested global horizontal method and a direct/diffuse method with the SolarCal model (differences on the order of 20%) but I imagine that this is because a mannequin human geometry is more sensitive to changes in solar orientation than a cylinder or plane. All of this is very good to know.
Yes, I guess this might be the case: the sensitivity of the SolarCal model to different parts of human body surfaces and surfaces areas.
Am I correct in understanding that you recently corrected the grey-body assumption about sky temperature in the Thermal Comfort Indices component with this commit? https://github.com/mostaphaRoudsari/ladybug/commit/a2a37b6dccc4e750...
The previous incoming long-wave radiation was derived by Ångström for clear sky conditions. The added correction "(1 + 0.22*((N/10)**2.75))" is a fractional cloudiness factor by Maykut and Church (I attached the publication below which mentions it).
So the emissivity coefficient of the (cloudy) sky is now:
epsilon_sky = (0.82 - 0.25*(10**(-0.094*0.75*e))) * (1 + 0.22*((N/10)**2.75))
I do not think that you could use the same value to calculate the sky temperature with Stefan-Boltzmann law, as the incoming long-wave radiation has been derived from the air temperature (2 meters above the ground), not the sky temperature. So by:
skyTemp = (La / [epsilon_sky * sigma])^0.25 - 273.15
One would get the air temperature from which La is derived, not skyTemp.The possible reason why SolCal Mean radiant temperature is currently getting similar values to Thermal Comfort Indices Mean radiant temperature could be that fact your epsilon_sky is almost equal to 1 (0.95), so it depends solely on La.I spoke with Dr. Blazejczyk, and got a publication on different sky temperature models. Apart from upper mentioned Swinbank, Berdahl-Martin, Melchor it has a lot more methods with mutual comparison of their resulting values. I attached it below.…
d react in length to the variation of their respective angle deviation from the sun.
For the moment I have established a way that depending on Bigger than/Smaller than X value, there is a dispatch of data to produce to types of panel lenghts. As you can see on the image.
But I would be interested to find the way to organize the list of all angles and classify them in groups like 5 packages of 20 degrees deviation. So, the panels deviated 16,3 and 27,9 degrees would go in the package of 15-35º, for example, and the 33,1 would go in the 35-45º...etc..
And the question would be to assign the different groups of angles, to given positions for the vectors that define the panel surfaces.
I am confused at how I should tackle this problem. Is it a question of dividing domains? Or creating sublists? But then, how can I assign the data to a set of positions? Dispatch only works with A/B..
And if so, how could I limit the positions of the vectors that define the surfaces, to a min and max length that would not overlap out of the base pattern?
These are huge questions, eh? But I'm sure that someone has tackled this problem before...
Looks like an accumulation of pretty standard problems,..but all together!
Thanks a million for any examples or hints on how this could work!

eps are represented by multiple surfaces so the discussed techniques are not fully workable.
the attached files include my test gh and a solid file to input. I have been able to map a suitable voronoi latticework onto the brep surface - but then I'm stuck. I cannot offset the curves on the brep and create a useable strut surface that way. I cannot intersect swept pipes with the brep surface to create surface patches that could then be joined.
I need some elegant ideas; I seem to be going down a rabbit hole at the moment where I am doing ever more complex workarounds for the grasshopper capabilities. (A case in point; the rail sweep is not working for me for closed 3D polylines, so I am having to cut them up and sweep and cap the segments. Ugh).

Curves on brep - but no simple offset / trim mechanism

imilar topic with a Windows 10 user, which successfully fixed this issue.If you are tiny little patient, I think we can try the same steps in your Windows 7 case.For start, try these three steps:1) Close Rhino. Restart your PC. 2) Once the PC boots up, double click on the "regMapWinGIS.cmd" file in "MapWinGIS" installation folder.3) When it closes the Command Prompt window it opened, try running Rhino, Grasshopper and drop the "Gismo Gismo" component on the canvas (Grasshopper working area).If this does not help (you get the same COM class factory CLSID error message coming out from the "Gismo Gismo" component), then try the following steps, one by one:
1) Close Grasshopper and Rhino2) Run the Revo Uninstaller Pro and uninstall your MapWinGIS application along with removing all the leftovers from the registry. You can download 30 days trial version of it from here. Here is a youtube example of a bit older Revo Uninstaller. But the important part is that is shows how registry leftovers are removed.3) Restart your PC, and once it boots again, make sure that you are logged in as an Adminstrator!4) 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".5) Turn off your Antivirus, which ever it is.6) Download the 64 bit version of v4.9.4.2 MapWinGIS.7) Right click on downloaded MapWinGIS-only-v4.9.4.2-x64.exe file, and choose "Properties". If there is "Unblock" button click on it, and then click on "OK". If there is no "Unblock" button, just click on "OK".8) Left double click on MapWinGIS-only-v4.9.4.2-x64.exe file and install it to "C:\dev\MapWinGIS" folder. Choose "Full installation" during installation process!9) In your Start menu's search box type: "CMD". Once the "Command prompt" appears do not left click on it! Instead right click on it, and choose "Run as Administrator".10) A command prompt window will open. Type the following command:
"your_regsvr32_folder_path\regsvr32.exe" /u /s c:\dev\mapwingis\mapwingis.ocx
If command does not result in an error message, then type this one afterwards:
"your_regsvr32_folder_path\regsvr32.exe" /s c:\dev\mapwingis\mapwingis.ocx
11) If no error appeared again, then open your Rhino and Grasshopper and check what "Gismo Gismo" component prints from its "readMe!" output.If errors appeared, please post their screenshots. Thank you in advance.
Please accept my apologies for the large number of steps. Some of them are quite simple actually (click on this, download that...).…

Meeting Agenda:
1) Discuss what the group would like to learn this term through our regular scheduled meetings. Topics include the priority and sequence of Grasshopper exercises we would like to explore during the winter term from http://www.digitaltoolbox.info/grasshopper_basic.html and Processing tutorials from the Processing Handbook I received from MIT.
2) Watch the Matt Storus Church Machine video and have a discussion about parametric and generative tools in design.
If you have a chance, please read the following article by Tim Love called Between Mission Statement and Parametric Model at:
http://places.designobserver.com/entry.html?entry=10757
3) Discuss a possible design build project over the following winter and spring terms using the skill set this group is developing. Conversation led by Chris Nielson (please see comments below for a brief backstory)
4) Discuss possible applied research and design work for the National Conference on the Beginning Design Student paper, Machine Craft and the Contemporary Designer: exploring parameters and variables through making physical artifacts. I wrote the attached abstract and submitted it for the conference the past fall and it was accepted. To continue with the research I need to assemble a team of students that will help explore the principles I set forth by making physical objects with the cnc router. In exchange for helping with the research I will show participants how to use the cnc router, how to author machine code and provide you with the cnc controller interface software necessary to simulate machine movements. Not to mention, your work will be sited in the research paper I present at the conference at UNC Charlotte in March. More tomorrow night, of course.
Thank you for your interest and I hope to see you there.
Sincerely,
Erik Hegre

All,
In response to Erik, who requested that I describe my intentions in a design-build project and to the article posted (definitely required reading for this group) I propose that we begin development of a project that spans the realm of "sustainable social" architecture and parametric design. The particulars of such a design do need to be made concrete, and it will be important to define the goals of such a project.
Therefore, I would suggest that this serve as a forum for the next few weeks for those interested in producing a built project. I agree with Nico that it may not be feasible to create the built piece, whatever it may be, this term; however we should have the groundwork and a plan in place by the end of the next 10 weeks.
Either way, I would ask that everyone who is interested to please provide as many concepts to this forum to begin a discussion. If you are indeed interested, please submit goals that this project could achieve (energy, socially, aesthetically, economically, related) and perhaps what you envision the project to physically be (shading device, public bench, water catchment, interactive thermal contraption, etc . . . )
I look forward to hearing your thoughts!
Cheers,
Christopher…
