We design sail catamarans from 40' to 80' and occasionally some other stuff.
One may know it's a quite uncertain activity so I find myself tacking upwind on other seas from time to time, such as product design and jewelry. I also have side projects with mates regarding hi-fi or RC planes.
As for "static" architecture I had a couple experiences working on large "complex" buildings. Sadly French architects are not very familiar with BIM, parametric or even precise 3d modeling so I've been hired to introduce GH in the workflow.
I'm an un-authorized rhino trainer, sorry to say, but I just love teaching and meeting new faces, although I'm not as devoted as Danny ;)
I've been using GH both for modeling and analysis for about three years now and I'll daresay I became pretty good at it... I'm not a geek at all but it's just so useful, and it's really worth it sometimes €€€!…
ke 20 samples per day, 50 days out of the year for 1000 samples) from each panel and calculate the % of occlusion. Allow that % to be the % "open" of each panel. Design the opening in each panel to be something cool and proportional. Profit.
You could even break it down by a finite number of available panel types(say 0%, 20%, 40%, 60%, 80% open) and create an efficient production. All of these things can be paramterized to allow for more samples or more panel types as needed or based on your calculation limits.
The only exception would be proper environmental analysis, say, if you were trying to reduce solar gain in summer and allow for it in winter. You would want to split this calculation between when you need to be gaining heat and where you want to be shading. Then extrapolate the percentage between the two. You may even need a gradient of heat gain through fall/spring. The possibilities depend on how much you know about the mechanical requirements of the area/building.
That would be my approach. If I have more time tonight I will try and put something together on this as its been something I'd like to have in my back pocket....
Edit: You would also need to analyze the angle of incidence as it could have an effect on the amount of solar gain.....…
pproach of estimating wind loads using design codes such as ASCE7-05.
B) Hiring a wind expert to construct a physical model and and calculate wind pressures measured directly from a wind tunnel test.
A) will allow you to derive a site specific wind design pressure based on the height of the building, surface roughness, site location etc. Typically you then multiply this pressure by an appropriate co-efficent in the code for a given building shape.
The other atypical method it to use numerical approaches such as CFD. This approach is not yet accepted due to nuances such as of surface roughness.
Building deflection is again subjective. Doing a modal analysis and getting an idea of the frequency is better. You can increase the frequency by playing about with the building stiffness.
You need to modify the stiffness of the building to get the deflection down. i.e. play about with geometry, add extra members with stiffness, reduce weight, use material with higher elastic modulus etc
If you are getting a 7m deflection for a 400m building then I can right away that is way too soft. That is equivalent to 400m/7m or H/57. You want to be at least H/500 to H/1000 so aim for 80 to 40 mm.
Your wind load seems reasonable at 87 psf for that height of building

oks like all your GH components are disabled? I just tried baking the cone from my earlier code and using that but can't see anything at all.
OH! You had 'Display | Shaded Preview' disabled - why? Now I see that you have 80 X 55 'SFrames', which will be VERY SLOW. I never understood why you abandon 'PopGeo'? But that many points will be extremely slow either way. I won't wait that long.
You're making this way too hard for me, bobbi.
I said early on that it's best to work with a very low count until everything works properly. Solid unions are one of the ragged edges of Grasshopper; slow and prone to failure, depending on the complexity of the geometry (co-planar surfaces, etc.).
Good luck!
P.S. I can see two problems here:
Surface normal is in instead of out.
You didn't 'Cap Holes' on the lofted tubes so they aren't solid "Closed Breps".
I have no clue what you're doing. Do you? :)…
k on forum?
or
B) install from a networked location?
Second question.
If you download from link do you:
A) read the post because you want to see what changes have occurred?
or
B) ignore the post as you are too excited to get the latest version up and running?
Third question.
When confronted by a demanding LOL cat telling you to update software do you:
A) nod approvingly and think "I must do that"?
or
B) freak out and get a sudden urge to eat cheeseburgers?
In all seriousness question three can be omitted.
EDIT: 80 views and only two posters! (thank you Simone and Luis).
I am actually interested in the results

of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

perforations that sift the light and with joints that are put together by
hand, it serves as a focus point in the big courtyard while visitors can
relax in the shade.
The pavilion is parametrically designed in Grasshopper and Rhino, and
loads, sun and shade, and material use has been optimized.
Steel sheets of 2 mm have been laser cut and rolled at the factory and
then assembled by hand in situ.
After summer the pavilion will be standing at Chalmers University of
Technology during the autumn, after which it is possible to purchase it.
The pavilion is a collaboration between Röhsska museum of Design, Chalmers
University of Technology and Ribo-verken, and is the result of 33
Architecture students' work during one semester, in the master level class
'Material and Detail'. After selecting one initial design, 33 students
have worked to develop the design, and to turn the project into a pavilion
which is safe and constructable.
The purpose of the course is to explore digital fabrication and to turn it
into a real, built architectural project.
Words on the design:
When talking to the staff at Röhsska at our first site visit, it became
clear that the courtyard, even though at the time covered with snow, could
get extremely hot during summer days. Adding this fact to the briefs'
demand for seating and the size of the empty courtyard, we set out to
create a pavilion that provided shaded seating inside it as well as
creating shaded spaces around it to place existing chairs and tables. The
pavilion therefore creates a network of spaces with the existing furniture
that altogether manages to inhabit the large courtyard, like different
small islands in an archipelago, which together with the technique of
rolling the steel in to arc segments gave it its name.
Well inside the pavilion you can lie comfortably on the smooth surface
that uses the steels excellent possibility to stay cool wheEn shaded.
Inside you find yourself in a space, the pavilion, within a space, the
courtyard, that creates a small but secluded getaway from the hectic city
life of central Gothenburg that is just outside the courtyard. The
perforation in the ceiling spreads out an organic pattern resembling the
one you would see from a tree in the forest. Contrasting the smooth
inside, the outside of the pavilion lets the visitor study in detail how
the 133 pieces are joint together with 1535 joints with a total of 3640
bolts holding it together.
