use an attractor curve to adjust curves that are being lofted to create a "wavey" surface. I've attached a picture to show the end result. Right now i create all the curves and then loft them together to create a surface which could then have a rib definition applied to it, and it works, my problem is that this project is for a 80' section of wall with ribs that would be a few inches apart, so that is a ton of curves i have to change everytime i want to adjust the overall shape. So is it possible to have an attractor curve that instead of adjusting the spacing of shapes in plane with the curve, would create high points or low points perpendicular to the curve? Hopefully that makes some sense, i'm having trouble finding the words to explain it, the attached pictures should help.
Any advice on how to do this would be great. I hate being that guy but this project came up last minute and it seemed like something the Grasshopper help save a ton of time in as far as adjustments go.
Thanks,
Kyle

h kangaroo and have found one project that illustrates my idea exactly...
https://vimeo.com/88002087
So far my best attempt has been to use a gridded surface in which the lines of the grid are springs, with a rest length at 80% of their initial length. (call this grid A) This is to simulate as if the material has been stretched 120% of its resting dimensions.
I have been trying to anchor the springs to a secondary grid (Grid B, curves that will be deposited onto the material) at the points of intersection with grid A.
I am not sure if this is the best approach, maybe soapfilm would be better? although i require the boundary (grid B) to adapt also...
Any advice or attempts to explain how Taichi Kuma has done this in his video would be greatly appreciated.
Thanks…
A: Who created it? / Copyright?
B: Anyone have a larger resolution copy of this image (or a vector so I can do a large resize).
Long and short - I'm an artist and I'd like to make a quilt out of that image. I need a decent resolution copy of it so I can do a huge resize and get a 76" x 80" crop out of it. I've tried resizing it in Photoshop, but by the time it's large enough, the quality has dropped below what is usable for my needs.
Thanks in advance! I totally understand I'm relying on the kindness of strangers here. (Also if this is inappropriate to post - please delete. Thank you)

st for the quality of the mesh.
Actually, convergence is much more than simply having low residuals. You can have a wrong solution with very low residuals. Usually, it is a combined process of both run time information on residuals and having an idea or expectation of what the simulation results should be. Another way of assessing convergence is if the residual values have been stable (within a very small limit, e.g. 1E-5) for more than a certain number of iterations (e.g. 1000). We are planning to provide run-time residual plots in Butterfly, hopefully soon. These plots can help keeping an eye on the solution.
You could try as a test if you want to switch to a blend of first and second order (by swapping upwind with linearUpwind in the fvSchemes)
.
Concerning mesh quality there are a number of ways, some of which are a bit advanced for this post and for BF's current capabilities. The best way to start is by refining the background mesh (i.e. the blockMesh). You can do that by assigning more cells to the x, y and z directions in the blockMesh component. However, make sure you increase the max global cells. I would suggest you monitor the output of the blockMesh in order to know the total number of cells there. Your max global cells has to be higher than that for SHM to even work. I'd suggest 2x to start with. Ofc all that requires a bit of trial and error depending on the case at hand.
Hope this helps!
Kind regards,

nnot calculate (too many digits).
Or you want just to fill that space with random configuration and find some good for you?
Here's my first thoughts:
Again, as some other cases, iterative process.
(Conway's game of life, a cellular_automata-like process (?)... Install anemone.)
I would create 3 grids:
1 - grid of 100 values, cell's center points
these values can have more integer values like 0=free 1=occuped
2 - grid of 81 values, grid vertex points (excludig perimeter)
these values are where the center of 2x2 cells could be. 0=possible location 1=not possible location
3 - "grid" of 180 values, grid segment center, where 1x2 center could be
again 0 and 1
Then it's needed a "topology" between those 3 grids:
At each iteration those values updates each other by basing on placed cells and adjacent values.
At each iteration a new cell (random from A or B) is placed in a random possible location.
This is just my madness, and maybe I'm already far away from a result.
For sure a fasterst, simpler, smarter solution exists.…
rsity building with 81 thermal zones. I wanted to use this model on my master thesis, but I am afraid I won't be able. So I would really appreciate some help.
The purpose was to set different insulation thicknesses and glazing types depending on the orientation. Therefore I created every zone by using "createHBsrfs" components. At the same time different zones would have different "building programs".
I created all the zones, I added windows as "child surfaces" for every zone. And I created the adjacencies. No errors or whatsoever.
But from this point I cannot connect the model to any other component without GH being frozen. So although the model is correct maybe it is to heavy for the software, however I am not sure if that is the reason.
Is it stupid what I have done? Is there any easier way to accomplish my purpose?
Any thought or help will be much appreciated.
I attach the GH file.
Thank you,
Eduard

ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,
Ding

n make it possible to Motivation generate
a variety of interesting objects, from abstract fractals to plant-like
branching structures, their modeling power is quite limited. A major
problem can be traced to the reduction of all lines to integer multiples
of the unit segment. As a result, even such a simple figure as an
isosceles right-angled triangle cannot be traced exactly, since the ratio
of its hypotenuse length to the length of a side is expressed by the irrational
number √2. Rational approximation of line length provides only
a limited solution, because the unit step must be the smallest common

√2
denominator of all line lengths in the modeled structure. Consequently,
the representation of a simple plant module, such as an internode, may
require a large number of symbols. The same argument applies to angles.
Problems become even more pronounced while simulating changes
to the modeled structure over time, since some growth functions cannot
be expressed conveniently using L-systems. Generally, it is difficult

to capture continuous phenomena, since the obvious technique of discretizing
continuous values may require a large number of quantization
levels, yielding L-systems with hundreds of symbols and productions.
Consequently, model specification becomes difficult, and the mathematical
beauty of L-systems is lost.
In order to solve similar problems, Lindenmayer proposed that numerical
parameters be associated with L-system symbols [83]. He illustrated
this idea by referring to the continuous development of branching
structures and diffusion of chemical compounds in a nonbranching filament
of Anabaena catenula.
The following is an example of its application:
starting string: A
p1: A F(1)[+A][-A]
P2: F(s) F(s*R)
which I think is basically trying to say
F(s) = move forwar a step of length s > 0.

bursts of calcium which interacts with a photoprotein to create flashes of light.
In the Pacific Canada Pavilion gallery at the Vancouver Aquarium, the public can excite origami jellies into creating beautiful patterns of colour and light using a touch screen controller.
When left alone, free from human intervention, the origami jellies instinctively react to each other. Random, generative displays of drifting coloured glow are triggered, not unlike jellies in their natural environment.
Jelly Swarm overhangs the gallery space. The soft, coloured light emitted by the jellies reflects on the aluminum surface. Viewed from below, the visual effect evokes looking up to the ocean's surface from undersea.
The installation features 94 origami jellies, folded in Tyvek. Each jelly contains its own RGB LED module. The 472ft² hanging surface was custom designed in 3D and fabricated from 6061T6 aluminum. Water jet cut and anodized on both sides, it comprises 154 generated triangles and 430 connector pieces.
Programed as self-contained objects capable of interacting with their closest neighbours, the Jelly LED modules are interrupted only by external intervention - the public engaging with the small display interface. Data is sent from an AIR app to each LED module via mbed wirelessly.
