and visualizing data for ENVI-Met 4 software. ENVI-met is a cutting edge software used to analyse microclimate interactions in urban environment. Tens of different analysis types can be performed on the chosen building context. From Mean radiant temperature and local Wind speed to CO2 concentration and Pollutant dispersion in the air. To generate the building context for Ladybug ENVI-met components, Antonello used Gismo:
An example similar to results in upper screenshots has been been attached below. To run it, Gismo, Ladybug and Human plugins need to be installed. To perform the ENVI-met analysis, download ENVI-met 4 Basic for free, and install it. Steps in the .gh example file have been labelled from 1 to 11. They mostly consist of just setting a boolean toggle to True. An exception to this are steps 6 (set the folder path of your ENVI-met application install folder), and 8 (running the ENVI-met simulation). Step 8 has been explained in detail in the photo attached below (step8.jpg). Special thanks to Antonello for developing and guidance on ENVI-met application and components! Post questions below if you have any issues!…

an almost planar tissue (your case) can cause a variety of issues up to the undo able state (metal parts/components grow in size as well for no reason). See forces estimated by FF below.
2. Therefor I strongly suggest to consider Plan B (a) mastermind a secondary "anchor" capability in order to achieve a far more stable system (b) use a mount design that can support this (and comply with the attractor concept of yours). Here's a variable mount custom system (mostly machined AND not cast) that is suitable for the scope (Rhino reads the stp file OK .... but makes a colossally big file - thus I attach here the original).
3. On first sight lot's of things in this system appear "odd". For instance: is it stable? Why these double cables are used? How far can be adjusted? (that's a classic case for feature driven parametric design - not doable with Rhino).
4. This concept (strut axis exported only) is tested in FORMFINDER and some other far more complex membrane apps that I use quite often (not RhinoMembrane). Here's is what FF tells us about:
Observe a different kind of "stress" when this is converted to radial type:
5. If you insert the stp file to the Rhino file provided (exactly as exported from FORMFINDER - no mods of mine of any kind) you'll see what goes where (and why). That way the usage of double cables is rather obvious (and a lot other things - for instance the way that the struts achieve "equilibrium", see the slots in the base mount plate.
6. If this approach is worth considering your definition requires some serious rethinking (far more simpler/manageable with the drawback that the real parts they are "static" they can adjust only as far this particular solution allows them to do - controlling them parametrically is clearly impossible with the current state of R/GH capabilities).`
All in all: this case works because the cables push the anchor points downwards and the struts push them upwards.

hat aren’t completely there. BIM will have to continue to evolve some more if their supporters want to get to realize the promise that still is. I can’t say much about PLM, but I would say that both BIM and PLM should be considered in future developments of GH and Rhino. David has said several times that some GH limitations regarding geometry and data structures (central to interoperability) are actually Rhino limitations. So, I wouldn’t put so much pressure on David for this, or at least I would distribute the pressure also on the core Rhino development team.
Talking about Rhino vs. GH geometry, there is one (1) wish I have: support for extrusion geometry. GH already inputs extrusion elements from Rhino, but they are converted to breps. Is not a bad thing per se. The problem is when you need to bake several breps that make the Rhino file to weight several hundred MB. When these breps are actually prismatic, extrusion-like solids, is a shame that they aren’t stored as Rhino V5’s extrusion geometry in a file of just a couple of MB (I overcame this once with an inelegant RhinoScript that wasn’t good for other people). This was one of RhinoBIM’s main arguments. We can develop a structural model made of I-beams in GH using the Extrude components. We should be able to bake them as extrusions. That would also work for urban models with thousands of prismatic massing buildings (e.g. extruded footprints). Even GH’s boxes are baked as breps! Baking boxes as extrusions could be practical for voxelated or Minecraft-like models.
(2) Collaborative network support. Maybe with worksession handling, or something that aloud project team members to work on a single definition or in external references or something alike. I know there is another Rhino limitation on this, but maybe clusters are already going in that direction?
And maybe on the plug-ins domain:
(3) Remote control panel that could be really “remote”, like from other computer or device. There is an old Android App for that, but is not only a matter of updating. I mean, it would be great to control a slider with the accelerometer of an Android phone, but to have that on an iPhone will require another development team. If GH could support networks, a remote counterpart of a RCP plug-in could be developed as a cross-platform web app. I don’t know if you can access accelerometer functionality through HTML5 already, but for now, asking a client (or an spectator or any stakeholder for that matter) to control your sliders from gestures of his/her own phone would be awesome (maybe Firefly will fill that hole?).
(4) GIS support. GH already imports .shp files. Meerkat can even access the database, but what about writing to shapefiles or generating our own with databases processed/generated in GH?
(5) SketchUp support. Not only starchitects and corporations are using GH in the AEC. There are a lot of small firms, freelancers and students interested. Most of them use SketchUp for 3D modeling (not CATIA, neither Revit). Yes, you can import/export .skp from Rhino, but if GH could support nested block at bake time (also mentioned by others), it could write .skp files with complex relations of blocks (that are called components in SketchUp) and nested groups, going beyond what Rhino can export.
(6) Read/Write other formats. There are some challenges with proprietary formats that are not completely supported by Rhino, but they’re still a lot of open formats that are relevant to the fields of GH users, like stl and ply for 3D-printing. It could be nice to write mesh colors to a ply for 3D-printing a colored prototype based on GH colors. There are others, like IGES, STEP, COLLADA, etc. and 2D, like svg, odg and pdf. Some of them could offer special formatting options like custom data that the format supports but nobody uses just because is impractical to access this from direct modeling environments (but not from visual programming).

can work in any node of a given hierarchy tree (loaded in your work session) by making the node "active". "Nodes" can be other things as well (like workplane, clip definitions etc).
Why to do that weird thing? Well, think any design being "flat" > meaning that all objects are placed in a single file (and in a single layer). Not that good > although the items are present you barely can handle them (because power is nothing without control, he he).
Let's go one step further: we can start classifying objects in "groups" (like a directories/files organization in any O/S). This means, in MCAD speak, creating assemblies (a void thing kinda like a directory) that contain components/entities (kinda like files).
Several steps further we end up with severely nested "arrangements" of entities (an assembly could be parent of something and child of something else).
For instance, it could be rather obvious the logical classification of a "geodetic" (so to speak) structure like this : a 40000m2 "hangar" defining some thematic park.
I mean : a void master that owns 4 equal void segment sets that own 4 "legs" that own various geodesic structural members + cables + membranes + you name it etc etc.
Each "leg" owns the concrete base (Shared) and a rather complex set of objects.
Notice that some tensile membrane "fixture" combos (see above)...act as perimeter light fixtures as well...meaning that the membrane tension plate may could be a child of a void "light" parent...or may could be a "stand alone" assembly etc etc.
These arrangements can be internal (belonging in, say, a x node within the current active file) or external (belonging in a y node within another file). If they deal with the same (topologically speaking) object they define clusters of Shared entities (or variations)- where only the view transformation matrix changes (in the simple scenario, he he). For instance the disk shown above is a Shared Assembly that owns the bolts, the plates, the tension member etc etc. Selective Instancing allows modifying some attributes without affecting the topology (i.e. the geometry).
The whole (terrible) mess is controlled by some tree like "dialog" (in Catia is "transparent") that is called Structure Browser. By controlled I mean (1) display/display mode with regard any tree member combo/selection set (assembly and/or component) in any View (2) clip state control (3) active status (for modifications/variations) (4) workplane control (5) drag and drop ownership control (6) ....
Now...what if I would chan…

eventually found out about genetic algorithms on which I found extensive researches, projects,... ! I looked into it and ended up on a few papers which I believe are the jumpstart for my master thesis.
"Galapagos; on the logic and limitations of generic solvers" by David RuttenArticle in Architectural Design 83(2) March 2013
"Black-box optimisation methods for architectural design" by Thomas Wortmann and Giacomo NanniciniConference Paper: CAADRIA 2016, At Melbourne, AU, Volume: 177-186
So I started looking into alternatives to genetic algorithms in architectural design.So far, I've ended up on :
Thomas Wortmann's work with the surrogate(or model) based optimization approach!You can check out the tool he developped for GH (Opossum):http://www.food4rhino.com/app/opossum-optimization-solver-surrogate-models
Judyta Cichocka's work, specially with the Swarm approachYou can check out the tool she developped for GH (Silvereye):http://www.food4rhino.com/app/silvereye-pso-based-solver
And that's it !!! I've been researching through article references (mainly on "researchgate") but I'm now stuck in a loop of references I already visited!That probably means the litterature on the subject is not (yet) extended but I might probably be missing something.The keywords make it difficult to search : "optimisation", "algorithms", "architecture", send me most of the time to computational engineering and deep mathematics papers I unfortunately do not have the background knowledge to comprehend ! So there it is ! If you have any clue of where (or how ! ) I should be looking, please tell me :)I know Mr Rutten is pretty active on the forum so hopefully... (fingers crossed :p) !Also if you have any good tips for getting into algorithms in general (you think could help), I'd be glad to hear(read) it ! A book, tutorials maybe ?!So, autors, architects, projects books, articles, conferences I should go to,specialized architecture offices/studios (I'm also looking for an internship so ...).If you know about a more appropriate forum please let me know !If you want to get deeper into this, you can contact me at :
e1635331@student.tuwien.ac.at
tdissaux@student.ulg.ac.be
My master thesis is due for may 2018 but I have a paper to write for January 2018 in order to be elligible for a PHD program afterwards.What I mean by that is that if you read this message in 6 month, I'll still be open to discussion !
I am right now an erasmus student at TUWien (Vienna) but my main university is The university of Liège in Belgium.I can handle French, English, Italian litterature and eventually Dutch if really you think it's worth it ! I have access to most online libraries via my university's portals so access shouldn't be an issue !I'm very excited to hear from you I wish you all a great day,Cheers,Thomas
