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!…

Il comfort visivo e la gestione dell’illuminazione naturale in relazione al risparmio energetico diventano sempre più rilevanti per una progettazione innovativa degli edifici. Ad esempio, il nuovo protocollo LEED 4 riconosce crediti per le simulazioni di daylighting e conferma l’importanza degli aspetti progettuali per “collegare gli occupanti con lo spazio esterno, rinforzare i ritmi circadiani, ridurre i consumi di energia elettrica per l’illuminazione artificiale con l’introduzione della luce naturale negli spazi”. Senza strumenti software per la simulazione della luce non è possibile ottenere risultati di qualità. Radiance è un software validato, utilizzato sia a livello di ricerca che dai progettisti ed è tra i più accurati per la simulazione professionale della luce naturale e artificiale. Non ha limiti di complessità geometrica ed è adatto a essere integrato in altri software di calcolo e interfacce grafiche. Queste ultime facilitano le procedure di programmazione. Le principali e più versatili saranno oggetto del corso (DIVA4Rhino e Ladybug+ Honeybee, plug-in per Grasshopper e Rhinoceros 3D).
Il corso è rivolto a progettisti e ricercatori che vogliano acquisire strumenti pratici per la simulazione con Radiance al fine di mettere a punto e verificare le soluzioni più adatte alle proprie esigenze. Sono previste lezioni di teoria e pratica con esempi ed esercitazioni volte a coprire in modo dimostrativo ed interattivo i concetti trattati.
Le domande di iscrizione devono essere presentate entro il 12 maggio 2016.

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) ....

oo culm and the web is mad of bamboo slats connected to the culms on either side of the attachment points. To make things clearer (extracted from the above paper):
The authors of the paper did a numerical beam-model in ANSYS to see if they could replicate their theoretical results, and it is fairly correct (some differences due to the non-linear behavior of the semi-ring joints that they use, they remain of an order of 5-10% difference in maximum deflection).
My problem is that I am not able to obtain the same deflection values that the authors did (11.4 mm for a total service load of 7.063 kN applied punctually on the upper chord where the truss elements meet, or even replicate the load/deflection curve). Using an orthotropic material, with the engineering constants taken from (ResearchGate - A bamboo Beam-Column Connection Capable to Transmit Moment), my model is too flexible and I get a maximum deflection of 24.28 mm. I tried other orthotropic mechanical characterizations from other sources (Kathry & Mishra, 2012, Finite element analysis of bamboo and joints using steel members under various loading conditions for design study and Chand , Shukla & Sharma, 2008, Analysis of Mechanical Behaviour of Bamboo (Dendrocalamus strictus) by Using FEM), to no avail.
Of course, the problem could be with the material properties I inputted but I am trying to contact the research team to see directly with them. In the meantime, I am looking to make sure the model itself is not flawed.
It also seems to me that gravity was not accounted for in the numerical of the paper, but it seemed to much of an oversight to be possible (still, the deflection curve of their paper goes through 0).
There are several points I am not quite sure about: after all I am still fairly new to Karamba3D and may still have some things to learn about the inner mechanics of the plugin.
The very first is: should I put eccentricities of the slat-elements of the truss in the definition of their cross-section (directly with the Cross Section box) or as an offset of the beam element (with the ModifyElem box)? I tried both approaches and they seem to yield similar results (max. deflection change by 0.65mm in my latest model).
Second is: is it good practice to subdivide the beam elements in more than one element (and connecting the pieces rigidly) in order to get better results? I imagine some meshing or subdivision is performed when the analysis is run but there is no way of visualizing it (that I found in any case). Subdividing the chord elements seems to give smoother deformation results (though I did not check stress I have to admit). My issue on this topic is that the subdivision of the slat-elements of the web is problematic. On the screenshot below, where the elements are divided in two, lets take the example of node 18. It seems to me that all elements of the diagonal element (28, 29, 34 & 35) are all rigidly connected to the node 18. 28 & 29 are not connected together, independently from 34 & 35. The added rigidity may not be a bad thing for my model, but it is not correct I think? Is there a way of solving the problem?

Thank you all in advance for any insight (even on the inner logics of Karamba)!

ts (other than Kangaroo - if required). Anyway notify if you want some taste of them (but they are a bit "chaotic" : too many parameters etc etc ...). Warning: Almost all are written with MCAD apps in mind: GH is used SOLELY as a graphical editor/topology solver and just makes the simplest instance definitions possible in order to send them (via STEP) to some MCAD (Frank G uses CATIA/Digital Project as you may probably know, CATIA is my favorite toy as well) for actually designing the components and composing the whole.
2. "Equality" in modules (panels/glass/lexan) it's not an issue (other than aesthetics). I mean cost wise since modules are prepared via CNC these days. I wouldn't suggest to waste your time with "equality" puzzles and completely ignoring the big picture (real-life) that is FAR and AWAY from aesthetics. I mean: assume that I of someone else or Daniel can "equalize" things (up to a point): Is this sufficient for designing a similar real-life solution? In plain English: don't get occupied by the tree and ignore the forest.
3. As regards the frame in most of cases some MERO type of modular system is used: either a "flat" dome-like arrangement or a classic spaceframe or a hybrid system [push: tubes, pull: cables]. Hybrids are the most WOW (and costly) for obvious reasons. When properly done (and combined with a planar glazing system) THIS is the star of the show.
4. As regards the skin we use either "hinged" custom stuctural/semi structural aluminum extrusions (they can adapt to different dihedrals up to a point) or classic custom planar SS16L systems that also can adapt to dihedrals. A custom planar glazing solution is hideously expensive, mind (say: 1K Euros per m2).
5. Smart Glass tech (changes light transmission properties under the application of voltage) is gradually penetrating the market especially in future bespoke designs.
So in a nutshell: these are "pro" territory - if I may use the term, thus I don't expect to find ANY similar "turn-key" solution in the very same sense that you can't find a tensile membrane turn-key solution.
Meaning that practices that can do it ... er ... they keep the cookies for themselves. …

which almost works...
I have 5 integer values in one string:
- When my input is the string "(25,0,0,0,175)" it is not assigned at all
- when my input is the string "25,0,0,0,175" it is assigned as 25000175 :)
- when my input is the string "25|0|0|0|175" it is assigned as 191 which is completely confusing :)
Can anyone point me into correct syntax of input string to be correctly parsed as a set of integers? I'm accessing Rhino+GH from external app so I can format the input in any appropriate way, yet I cannot directly modify the GH script that uses these Integer Parameters as a way to handle input.
Regards,
Boris…
