3. Design a custom aluminum beam (or contact Fipa) - BTW. Chinese do custom stuff for peanuts money.
4. Create the vault LBS first using the beams (the "skeleton").
5. Study Migua elastic inserts (critical) and Ceresit PE/S sealants. Get the gist of bridging gaps as a pro.
6. Use marine grade plywood only as a facet top cover (and some proper false ceiling). Plywood dimensions are usually 1.20 * 2.20 m. A 25 mm sheet could be OK for a small vault. DO NOT varnish the plywood. Epoxy glue linear aluminum L (10/10 mm) along the upper lips (in order to allow silicone to adhere properly (not shown in the image below) : failing to do that ... buy an umbrella).
7. Use trigonometry to calculate the variable beam placement per module.
Do this:

s the "Surface Populating" definition: I manage to populate my geometry over the surface, but after I bake it, I have to delete the boxes that define my components limits as well! Is there any way of populating and baking only the chosen component, without having to delete the boxes afterwards?
Secondly:
Basically: I am trying to cover a surface with two types of components [ an open one and a closed one] , which will be proliferated over my tubular surface according to the main sunlight direction.
1. I introduce the surface component.
2. I use "Divide Interval2" in order to have division into U and V.
3. i generate the target boxes [ "surfaceBox"] .
4. I use "Isotrim" ( same intervals) and "BRepArea" to find centroid of each area.
5. My "Curve" component introduces sun angle, with its "End Points".
6. I use "Vector 2Pt" to specify sun-light direction.
7. I want to measure the angle between sun-light and the surface normals, at the position of each component; after generating the centre points, I need the normals of each centre point to get the surface's points' UV, and "Evaluate" the srf at points.
8."Angle" and "Vector" components: I use them in order to evaluate the angle between the sun direction and the srf.
9. I convert this angle to degree by using a "Function" [ to see if the angle is bigger from the max.angle or not...]
10. Function "x,y" gives me boolean data.
11. Data become "Dispatch"ed...
12. Two "Morph" components , each one linked to one part of the "Dispatch" data, generate "closed" and "open" components over the srf.
The result should have been different types of components, based on the surface's curvature, diraction and sun-light direction...
I do not understand where the mistake is in this definition...

l the changes you want and then close it again, you'll only have to recalculate once, whereas adding 3 inputs via the ZUI would recalculate 3 times right away and once more after you've changed the cluster to hook up the new inputs.
Does the cluster recalculate the entire solution, even though the new input hooks aren't connected to anything? Would it be possible to not recompute (not call ExpireSolution or its equivalent?) when an input parameter is added via the ZUI only? Could this be done by adding a flag on each input hook added by the ZUI, triggering the flag when the input hook is connected to a parameter, and recalculating the cluster only when the flag has been triggered?
Also, the current behavior, I think, is actually different. In order to work with the cluster, you need to see the geometry/data you're working with, so you have to enter the cluster, add the hooks, leave the cluster, connect the hooks to parameters, enter the cluster, play around in Grasshopper, exit the cluster:
Double click cluster.
Navigate to where you want to add new hooks.
Add hook (either from the toolbars, or by copy/pasting existing ones, or by double click search)
Close and Save Cluster. This will cause a new extra-cluster solution which may take some time to complete. (1 ECSOLUTION)
Connect new inputs with relevant parameters in the parent document.
Double click cluster.
Connect hook to relevant parameter. This will cause a new intra-cluster solution which may take some time to complete. (input * ICSOLUTION)
Repeat 7 until satisfied.
Close and Save Cluster. This will cause a new extra-cluster solution which may take some time to complete. (1 ECSOLUTION)
Which comes to: 2 extra-cluster solutions, and N intra-cluster solutions, where N is the number of new inputs. The cluster was opened and closed twice.
Zoom in on cluster.
Click on the (+) symbols to add inputs. Each input added via the ZUI doesn't recompute, since we know that the input hooks created this way aren't connected.
Connect new inputs with relevant parameters in the parent document. Also no new solutions.
Double click cluster.
Navigate to where the new input hooks were created (Perhaps aligned vertically, below the last-most input hook?)
Probably move the hook to a more meaningful location.
Connect hook to relevant parameter. This will cause a new intra-cluster solution which may take some time to complete. (input * ICSOLUTION)
Repeat 7 until satisfied.
Close and Save Cluster. This will cause a new extra-cluster solution which may take some time to complete. (1 ECSOLUTION)
Which comes to: 1 extra-cluster solutions, and N intra-cluster solutions, where N is the number of new inputs. PLUS, you only had to enter/exit the cluster once.
Thanks again, David!

This I found by following the instructions here:

HOWEVER:
At home here on my newer, faster Windows 10 machine - no such luck. This is becoming quite frustrating as I feel I am failing some obscure intelligence test.
I have attached what I suspect is the likely problem identifier - not that it has helped me identify the fix. What I believe is the salient message is appears in the OF_Env_Create Powershell Window (Running as Administrator) , which is step 3 on the Windows 10 special instructions found here:
https://github.com/ladybug-tools/butterfly/wiki/Windows-10-Installation-Notes

ld work.
For example there's a grid shell and I've got a number of control points (for example 3) that can move up and down.
Depending on the control points I get forms that are structurally good and some that are bad.
In my office we've got a GH-Component, which leads the geometry in structural members and solves the structural forces and so on through an external Software called Sofistik and afterwards gives back to GH some Values, for example maximum bending moments. (Like Karamba)
Now I want to create this optimization component or something like that to minimize e.g. the bending moments in the given geometry.
Let's start with the work of the component.
So when I've three control points that can only move in z-direction.
P1(0,0,Z1), P2(10,0,Z2), P3(5,5,Z3)
They only depend on Z, so everything depends on Z1 to Z3 which have a range between 0 and 10 f.e.
First I want to get some (between 9 and 15) random Particles, one particle consists of this 3 different Z's.
So for example the first particle Part1 is [Z1=10, Z2=5, Z3=7]
and the second particle Part2 is [Z1=7, Z2=1, Z3=9]
and so on.
I created these Start Particles in a Cluster. See attached file.
I also tried this in C#, but thought it is easier in GH.
After I've got the Start Particles I want to give out the first particle and evaluate with its including Z's the target value in GH. Therefore I had to take the first branch and graft this branch (Discussion before)
Afterwards I want to save this Target Value that depends on the first starting Particle. Then I want to give out the second starting Particle to evaluate its target Value and store it. And so on till the last target Value of the last Starting Particle got assigned.
Then I want to assign the particles with its target values. E.g. part1: t=0.9, part2: t=1.8...
Then I want to define neighborhoods or the count of the expected local minima.
These neighborhoods can look like: Each neighborhood has to include not less than 3 particles. And the particles have to be next to each other.
E.g. if there are 12 particles and I want to have a look for 3 local minima, I need 3 or 4 neighborhoods. Then I would take 3 neighborhoods, because the more particles in one neighborhood, the better.
So the Count of the neighborhoods would be N=min{(Count of Part/3)& N_min}
How to define these neighborhoods I don't know at the moment. I think it has to be searched for the distance between the particles. E.g. part1 with (9,9,9) and part2 with (9,9,8) are next to each other but part 3 with(1,1,2) is far away.
Then each StartParticle is set to Partx_localbest.
And in each Neighbourhood the best of these localbeststs is Part_NyBest. (The best ist the one with the smallest target Value)
Loop:
Now I want to create new Particles. These Particles don't change their Z-values randomly. They change their Z-Values depending on Part_NxBest and Part_localBest. Therefore it has to be evaluated a new velocityfactor with v_Partx_new=0,792*v_PartxOld+1,5*random(0,1)*(partx_localbest-partx)+1,5*random(0,1)*(part_NyBest-partx)
The new particles will then be partx_new=partx+v_Partx_new.
The new Particle partx_new will be set to partx and then set in the output.
then there has to be caught the targetValue of part1 afterwards part2 can be put out and its target value caught and so on.
Then it has to be looked for the Partx_localbest through comparing the partx_localbest and its target value with the new part_x and its target value. If the target value of the new partx is smaller than partx_localbest,
then partx_localbest is the new partx.
This has to be done for each partx. Afterwards the same for neighborhoods best (best of all partx_localbest in one neighborhood)
Endloop if velocity gets small.
Output all part_NxBest
Output all targetvalues of the part_NxBests.
So in the Input there have to be:
StartParticles if they are given through the cluster attached.
Device on the target Value like in the attached gh.file from David Rutten I found in the discussions
Count of neighborhoods
And in the output
Output particle for evaluation
Output all part_NxBest
Output all targetvalues of the part_NxBests
Hope didn’t forget anything. And hope it isn’t crushed to badly. Sorry for my bad English by the way ;-)
For more explanation, how the PSO works in other programs. There’s attached a workflow script (is it called like that?) I think for GH it should be a little bit changed like I tried in my explanations.
So if you can help me a in some parts or you have any advices would be great, otherwise thank you nevertheless!!!!
Thankfully there’s no limit for the words in the discussions :-D
Best, Heiko

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…

1. Select a building to mount a photovoltaic generator on (seen in Rhino in green).
2. Select a surface within that building to mount a photovoltaic generator on (seen in Rhino in green).
3. Create a Honeybee context surface from that surface.
4. Place a photovoltaic generator on that Honeybee context surface by using the Honeybee generation component. Honeybee_Generator_PV and connecting the context surface to it's input _HBSurfaces. Then you can specify both the performance and the financial data of the photovoltaic generator.
5. Create a Honeybee generation system which consists of the photovoltaic generator in 4. By using the component Honeybee_generationsystem and connecting 4 to its input PVHBSurfaces_. Then you can specify the annual maintenance cost of this system.
6. Run the simulation in Energy Plus by connecting 5. to the input HBGenerators_.
7. Read the results of the simulation:
- The electricity produced by the Honeybee generation system in 5.
- The net purchased electricity of the facility (the Honeybee zone) to which the Honeybee generation system is attached to. This is the electricity consumed by the facility less the electricity generated by the Honeybee generation system.
- The financial costs of the Honeybee generation system; capital, maintenance and replacement costs.
8. Calculate the net present cost of the Honeybee generation system in 5 assuming a 25 year lifetime.
9. Visualise the net present cost.

this was about some boring building I wouldn't respond ... but here we are talking sardines.
Here's my take on that matter:
1. The 4 C# first create/use a nurbs, then define some random planes (and transformations) and then (a) either they place some humble stripes or ... er ... (b) sardines as instance definitions (NOTE: Load Rhino file first).
2. All important decisions are the ones in yellow groups.
3. You control what you get via this (priority on stripes or sardines? that's the 1M Q):
4. If you decide for sardines (the right thing to do) then you must ENABLE the Sardiniser(C)(tm)(US patent pending) as follows:
5. The vodkaFactor on that Sardiniser C# adds some spice in the sardine placement (it does that by altering the priority on the "composite" transformation in use: first randomly rotate then planeToPlane .... or the other thing?).
6. Only the finest Da Morgada sardines are used in this definition:
7. Spot the WARNING in the filter related with what sardine to choose > do it wrong and no hard disk on your workstation > no risk no fun > sorry Amigos, he he.
8. 1M question for you all: why placing sardines (it's real-time you know) is WAY faster than creating these humble stripes?
9. Although the sardines are placed in real time as regards your CPU ... the critical factor is your GPU (display mode: rendered).
10.Still WIP (dancing sardines in the next update).
have some sardine fun, best, Lord of SardineLand…
