truss right?
2. Trusses are NOT made via lines ... they are made by real-life components like balls, rods and other mysterious (and maybe ominous, he he) paraphernalia.Good news for you: lot's of C# stuff around me that do that (but they are not exactly "entry-level").
3. PRIOR talking to ANY FEA/FIM thingy you need to address clash situations: I mean IF a given node is doable or not (because lines they don't rise clash issues ... but rods/struts/tubes/cones do). Good news for you: lot's of C# stuff around me that do that (but they are not exactly "entry-level").
4. Then you have to use some real-life (or at least some "realistic") components like the ones found in, say, a classic MERO "ball" system (and especially the adapter cones between the balls and the tubes). Or at least "some" of them that outline a "realistic" truss.Good news for you: see above.
5. Then you could validate the whole structure AND the parts VS structural loads: I mean there's absolutely no meaning "doing the whole" without taking into account the load bearing capability of the parts. For instance, say, what happens if the geometry (i.e. the topology) is "capable" but a given bolt is weak? That sort of stuff.
6. Now ... this is Academic ... but following the "abstract" way (I don't care about bolts because I'm a student)... this could teach you the entirely wrong way to use FEA/FIM for validating any structural ability of ... anything. And besides FEA/FIM is used for making the damn thing in the real-world ... and that involves (unfortunately) "some" bolts and nuts.
I can arrange a (rather long) Skype session for a demo of all the above ... but first I strongly advise to post here a finished thing (in terms of 3d component geometry) ... and THEN we can examine the whole strategy: what to export, how and especially what could be an "interactive" (both ways) protocol/strategy in order to give the green light for that truss.
BTW: Kangaroo is a physics engine and as such it's used as an abstract "shape" finder. I have no idea what Karamba does ... but always have in mind: BIM things ... are BIM things (meaning that without a serious BIM umbrella ... don't go out when it rains).…
gns. There were a few issues with your case. I will try to list them, hoping that this can also be helpful to you but also other users in the forum.
1. The Rhino model contained a lot of open polysurfaces. This is a big enemy of meshing and CFD. The way meshing works is that every single open area, that can be reached from your locationInMesh with a polyline, will be included in meshing. Some of your lanscape volumes were open. I have rectified this in the .gh file attached and now they should be ok to mesh.
2. It is strongly suggested to rotate the geometry and not the incoming wind when creating the wind tunnel. This might as well have been the reason for meshing awkwardly, although can't be sure. I have rotated the geometry by 45 degrees to allow your original wind to have a Y+ direction.
3. I could see a decomposition component in your case study although I cannot be sure if this could be the reason of your problems. It was not connected to anything, but perhaps it might have been the culprit for the paralle issues you were having. I have disabled the component so the case would run in single processor, but you can freely enable it and your case will be run in parallel (4 cores).
4. Your post-processing surfaces have large parts inside the building volumes and under the landscape (if included). You will probably get some issues with visualizing some probes, although this will not affect your study in any way. I recommend to only pass probes that you know to be sure will be inside the mesh to OF.
5. If you decide to include the landscape (I have it disabled in the attached .gh file) I strongly recommend to allow for more cells than 2m. 10m would be a good start imo for this case.
6. I did not check, as it will not make your case break, but your grading was a bit imbalanced at first glance. Try and keep some balance, especially in the X-direction, and make sure to visualize the blockMesh and make sure you achieved what you had in mind.
I did not actually run the case btw, I leave that to you. I believe it will run without problems, although I cannot be sure it will not diverge (this is something that is very educational for you to deal with).
Good luck!

e curve and uses the resulting surface/subdivisions to:
1. Smooth wall surface, varied via the Image Mapper
2. Segmented wall surface, varied via the Image Mapper
3. Populate the surface with spheres (with or without the "wall" surface)
4. Ribbed wall surface (Horizontal and / or Vertical)
5. Protrussions from the surface, driven by Image Sampler
6. Wall of Tubes, driven by Image Sampler
7. Gridded Web Surface
The options have to be enabled/disabled to achieve various results, but the idea is that this script permits a variety of looks, all in one script. See attachments at bottom.
I think this is a decent example file showing a variety of things that can be done using the Image Sampler Component in Grasshopper. This is a working version, so I am sure there are a lot better ways to achieve some of these effects. Hopefully, this will help some of you out and / or inspire some ew idea.
In the script, there is a User Object I downloaded from digitalsubstance. It is a self contained point attractor cluster, super cool, super fun. Link to the site is below.

he Summer in the City program, part of the Portland School of Architecture and Allied Arts (an extension to University of Oregon).
Using both Grasshopper and the Firefly plug-in, this workshop will focus on the design of innovative facade prototypes that are configurable, sensate, and active. Students will become familiar with the terminology used in interactive facade design including an overview of hardware (ie.sensors, actuators, and programmable microcontrollers) as well as software interfaces terminology. We'll learn new prototyping techniques and develop digital and physical models which can respond to a plurality of environmental and user driven forces. This workshop will take a hands-on approach, and you will walk away with the ability to build your own custom electronic circuits (using the Arduino), as well as create interactive simulations and models.
This course will primarily focus on physical computing techniques. Unfortunately, given the time constraints of the workshop, I will not be able to provide an extensive overview of the Grasshopper interface (it is suggested that participants have some familiarity with the Rhino/Grasshopper environment). There are many great online resources to get you up to speed relatively quickly if you are new to this software. This is a good place to start.
The course will be held at the School of Architecture and Allied Arts in Portland, OR. The date/times of the workshop are as follows:
Friday July 19, 5:00-7:50 P.M.
Saturday July 20, 9:00 A.M.-3:50 P.M.
Sunday July 21, 1:00-3:50 P.M.
If you are a designer, architect, or anyone who is interested in learning about the digital tools and technology trends that are revolutionizing design today, this workshop is for you. Make sure to click here to find out more about registration and enrollment in this exciting new workshop.…

Shape Routine:
Diagrid Routine:
Example and Inspiration:http://www.solaripedia.com/images/large/4226.jpg
Goals:
The goal is to create a grasshopper routine that recreates a modifiable design concept as shown in the concept images. The following parameters should be modifiable
1) The size and elevation of all the basic triangles, circles and the ellipse.
2) The elevation and shape of the opening and the shape and size of the three legs.
3) The shape of the crown. The angle of the tilted ellipse.
4) The loft shape between the edges.
5) The grid size (U,V) of the diagrid.
6) The size of the 2 pipes used for the structure.
Rhino Grasshopper Workflow:
I attempted Boolean difference of a solid (Brep) and the surface in question to create the opening in the surface as shown above but that did not work. What should i do to recreate the concept in grasshopper ? I would appreciate any feedback and advice. Thank you very much !

le] demo):
1. A transformation Matrix is a 4*4 collection of 16 values that "deform" 3d things according the values in the cells. The orthodox way is to deploy "cells" left to right and top to bottom. Rhino does the opposite (why?) hence we need the transpose method.
2. Since "translate" and "perspective" are "symmetrical" the transpose boolean toggle (within the C#) "flips" rows with columns ... so we get perspective or move.
3. When in perspective "mode" the vanishing points are computed internally within a min/max limit (per X/Y/Z axis) thus avoiding the usual havoc with "extreme" perspective angles (very common "glitz" in pretty much every CAD app - CATIA excluded). Vanishing points (and limits) are oriented with respect the pos/neg value of a given control slider.
Note: slider values are percentages between min/max (mode: perspective) and/or actual values*100 (mode: move).
4.In order to start mastering the whole thing: don't change anything: just play with these 4 sliders selected:
5. The 123 sardine cans challenge: even with DeusExMachine = true (see inside C#: that one redirects the transformation per BrepFace and then joins the breps instead of applying it on a brep basis)... odd things (and/or invalid breps) occur ... thus what is required in order to make things working 100% ??.

I followed these instructions, succeeded to build Tetgen, placed the built files in C drive directory and tried to run the definition. Then some WindowsError came out as follows which I don't know how to fix.
My working environment is;
OS is Windows 7 Ultimate 64 bit.
Rhino is version 5, 64 bit.
Grashoppper is version 0.9.0076, the latest version at this moment.
It would be great if I can have some help advice / comment.
I appreciate for your attention.

when the trimmed shapes (red) are small enough, they just dissapear.
Then, the main shape (green) appears again, but as a trimmed shape (red).
I tested it with other elements, like Solid Difference. It performs pretty well, but I just need the trimmed shapes (red) that are above the trimming shape (blue), and with Solid Difference, the collision also happens inside the trimming shape (blue), and that´s not what I am looking for.
Attached some pictures of what I mean. I hope I made myself clear.
Any suggestions?.
Thanks a lot!
1- Good performance
2- Good performance (Without trimming shape)
3- Left side shows the cut on the main shape, but fail to show the trimmed shape (red)
4- Same on the right side
5- It shows everything but in red colour, as a trimmed shape
