sinergetici associati alla compresenza simultanea di differenti strumenti di analisi e digital design all'interno di un processo di progettazione in svolgimento. I partecipanti utilizzeranno Grasshopper (modellatore parametrico per Rhino): l'uso di questo editor grafico di algoritmi si integra alla perfezione con gli strumenti di modellazione di Rhinoceros 3D espandendo le possibilità di corstruire modelli parametrici altamente complessi. Per generare una complessità simile saranno utilizzati collegamenti live ai diversi programmi elencati di seguito: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI Durante questi intensi 3 giorni, i partecipanti impareranno il workflow dei plug-ins con l'aiuto di esempi esplorando una panoramica dei differenti software, le possibilità di testare le performances di un progetto o l'uso di strumenti addizionali non legati ad un singolo sistema (es. accentuazione, formazione, reazione parametrica) [english text] The focus of the workshop is to integrate and correlate the synergistic effect associated with simultaneous presence of different digital design- and analysis tools in an ongoing design process. The main attention is set on easy to handle interface , which should be used at a early stage of conceptual design to respond to external and internal influences in a intelligent and sustainable way. Participants will use the software Grasshopper as a parametric modeling plug-in for Rhino. The usage of this graphical algorithm editor tightly integrated with Rhino's 3-D modeling tools open up the possibility to construct highly parametrical complex models. To generate this complexity we will use live linkages to several programs listed below: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI In this 3 intense days, the participants should learn the workflow of the plug-ins with the help of examples and get an overview of the different software's, there possibilities for evaluating the performance of a design or the usage of additional tools to be not chained to a single system . (e.g. parametrical accentuation, parametrical formation, parametrical reaction) [.] Dettagli : Istruttori: Thomas Grabner & Ursula Frick from [uto]. lingua del corso: inglese (saranno disponibili tutor di supporto ma è richiesta una conoscenza di base della lingua unglese).

nside the zone. I would move your comfort evaluation surface to be 1 meter off the ground in order to be representative of typical human height.
Also, you did not intersect the ground with the rest of the zone geometry, resulting in an incorrect energy simulation. After intersection, you also get one surface of the ground zone that is not inside any buildings. I fixed these two things in the attached file ad it works:
I would also recommend breaking the top surface of the ground up into sub-surfaces so that you can capture the variation in ground surface temperature that happens across the outdoors. Second, I would recommend putting some windows on your buildings as the exterior surface temperature of windows can be very different than that of opaque surfaces. Finally, you should keep in mind that the outdoor maps are assuming a very basic outdoor wind profile by default and, to accurately understand outdoor comfort, you really should be incorporating wind patterns after running a CFD. This discussion has some information about importing CFD from other programs to GH:

ive 'correct' normal.
Non-normalized cross products is effectively weighting face normals by area, and is fast and simple, so we put that one as the default.
In some cases normalizing the cross-products improves the result, but not always.
Another option is to weight by angles, though this is computationally slightly more expensive, so might not be ideal for real-time updates on large meshes.
As an example, here is a mesh with a 90° corner, and uneven meshing on the 2 sides.
The arrows show:
0- Area weighted (non-normalized cross products)
1- Angle weighted
2- Normalized cross-products
Here the angle-weighted normal is the one at 45°, which is intuitively the 'best' one in this case.
These 3 seem to be the most commonly used, but there are many other possible definitions of normals - such as inverse-area weighted, mean curvature, etc...
I think really what would be best would be to put a few of these into Plankton, and include an optional argument in GetNormal for selecting which one you need for a particular application.

us allows Grasshopper authors to stream geometry to the web in real time. It works like a chatroom for parametric geometry, and allows for on-the-fly 3D model mashups in the web browser. Multiple [Grasshopper] authors can stream geometry into a shared 3D environment on the web – a Platypus Session – and multiple viewers can join that session on 3dplatyp.us to interact with the 3D model. Platypus can be used to present parametric 3D models to a remote audience, to quickly collaborate with other Grasshopper users, or both!
You can down load the Grasshopper plugin at food4rhino, and visit 3dplatyp.us to view your geometry on the web. This first round of Alpha testing will run for two weeks, until April 24 2014, after which the Grasshopper components will not solve.
We are very interested in hearing feedback from the community while the project is still in the prototyping stages of development. Please use the comments on this discussion to ask questions, suggest ideas, report bugs, etc. We are planning on rolling out another public alpha release or two this Spring, depending on how this first one goes, in advance of our Technology Symposium and Hackathon in New York.
Check out our getting started video below, and enjoy!

e rod with circular section (no goals allow for controlling torsion for what I know). The rods are set with two options, with straight rest position or the (initial) bent one. The calibration integrated with the model is more about giving a scale between the forces rather than the will to accurately simulate them (at the moment). Anyway, I am trying to do it on a macro scale, instead of a micro, with elements which are rather thin.
The system at the moment is not stable. In fact, besides the rods' characteristics is quite fundamental to keep them planar when they intersect. I am lacking something but also probably missing some parameters. In the script, there are two goals to define this: impose 90° between vertical and horizontal, as well as between these and a normal to their intersection. For my understanding, angle goal works tri-dimensionally without a preferred plane and this (hopefully) should address it.
Just wondering if anyone can give me a hint on this. After this step, it would be great to understand if the system can get out of its plane (through a pull force out of its plane, simulated in the script through point loads in the joints). I am still not entirely sure about the possibility of doing this. By looking at how other auxetic patterns have been used to generate freeform surfaces, I am giving it a try.
Thank you
Claudio
PS: I noticed also this post and this, really interesting. I see the problematic over the stability and the necessity to separate the states with an energetic hill in the first, as well as some potential in using auxetics in the latter.…
opening a simple file with 30 curves being lofted took like 2 minutes to complete and Rhino crashed afterwards saying:"Windows is out of memory and Rhino will close after you click ok."evethough I still had 7GB of free physical memory and my page file is set also to 16 GB just to be shure...I then switched to Rhino 5.0 Version 5 SR14 64-bit (5.14.522.8390, 05/22/2017) which also had big problems to display the lofted surface. It was unresponsive after loading the file for a minute and a half and then it normally displayed the lofted surface. Every move of camera takes at least 10 seconds to update, but at least it runs. GH profiler says the loft took only 12 ms (90%).
So I'm suspected my graphics card, because the Windows are just three weeks from a clean install. I've also updated my Graphics Driver from the stock Windows one to Intel HD one, but nothing changed.Is there something I'm missing??? What can I try next?My specs:CPU: i5-3320M @ 2.60 GHzRAM: 16 GBGPU: Intel HD Graphics 4000, driver: 07.04. 2017, version 10.18.10.4653

ino al suo utilizzo per la risoluzione di tematiche di modellazione complessa di ARCHITETTURA e DESIGN.Durante le lezioni si insegneranno i comandi avanzati del software Rhinoceros ed inoltre i discenti, alla fine del percorso formativo saranno anche in grado di creare modelli attraverso il linguaggio della Plug-in avanzata Grasshopper(http://www.grasshopper3d.com/photo).
Il workshop si divide in due moduli che possono essere frequentati anche separatamente:
STRUTTURA
mod.1 _MODELLAZIONE BASE con Rhinoceros | Venerdì 14 Dicembre e Sabato 15 Dicembre | dalle 10,00 alle 19,00
Scadenza iscrizione: Lunedì 10 Dicembre
mod.2 _MODELLAZIONE AVANZATA con Rhinoceros e Grasshopper | Domenica 16 Dicembre e Lunedì 17 Dicembre | dalle 10,00 alle 19,00
Scadenza iscrizione: Mercoledì 12 Dicembre
SINTESI
mod.1 _MODELLAZIONE BASE con Rhinoceros
L’obbiettivo del corso è quello di insegnare in tempi brevi, gli strumenti base della modellazione 2D e 3D e la renderizzazione dei modelli creati. Le ore saranno dedicate allo studio dell’interfaccia del software Rhinoceros e all’apprendimento dei comandi base per la gestione del documento di progetto; si approfondiranno i comandi più utilizzati per l’editing e la costruzione del disegno per arrivare alle operazioni booleane semplici e complesse. Inoltre si imparerà a costruire e trasformare curve e superfici free-form. Le nozioni ed i metodi verranno trasmessi trattando temi e problematiche reali di design ed architettura.
mod.2 _MODELLAZIONE AVANZATA con Rhinoceros e Grasshopper
Il secondo modulo tratterà forme complesse implementando la modellazione avanzata di Rhinoceros con le potenzialità espresse dalla plug-in Grasshopper. La plug-in di Rhinoceros permette di disegnare abbandonando l’usuale interfaccia dei software di rappresentazione, consentendo un rapporto più diretto con il linguaggio proprio del computer: la programmazione. Questo cambiamento porta ad una radicale variazione del rapporto che il progettista ha con lo strumento di rappresentazione digitale. I partecipanti saranno orientati verso un nuovo rapporto con le forme create che oltre ad essere frutto di trasformazioni delle entità primitive che Rhinoceros propone, si costruiranno anche in relazione a parametri variabili.
Nel corso si imparerà a comporre algoritmi semplici, di carattere principalmente geometrico, in grado di generare forme e gestire i comportamenti delle stesse se sottoposte a variabili esterne.
In fine si imparerà a confrontarsi con un contesto evolutivo, che influenza i parametri della rappresentazione portando a dei modelli dinamici.
