j), runs simulation in Contam and re-imports results back into Grasshopper for visualization and data processing. Contam (developed by NIST) is a multizone indoor air quality and ventilation analysis computer program. It can be used to determine infiltration, exfiltration, and room-to-room airflows in building systems driven by mechanical means, wind pressures acting on the exterior of the building, and buoyancy effects induced by the indoor and outdoor air temperature difference. You can read more about Contam at NIST website: https://www.nist.gov/services-resources/software/contam
Installation

The thing is that if I raise the -aa parameter from 0.05 to 0.1 all works fine..
Is this only related to my PC then?? What should I do to solve this issue?
Thanks again for your help

ake a network of lines (i.e. a graph) and make a Plankton Mesh, from which you can use Cytoskeleton to make a solid mesh (and then smooth it with Weaverbird).
Works with ngons (polygons with 3 or more sides). Other examples I found only worked with tris and quads.
Works on open or closed surfaces
While these examples start with a surface, you could start with a network of lines and make a patch surface
This is meant for 2D networks/surfaces. I haven't attempted filling a 3D volume. My guess is this wouldn't work as it would require a non-manifold mesh that Plankton wouldn't handle.
Note similar results could be achieved with the following:
TSplines
MeshDual (dual of a tri mesh, not as much freedom/control)
Working backwards, here is the GhPython script from Will Pearson that builds a Plankton Mesh from vertices and faces. The vertices are a list of 3D coordinates, the faces are a tree a lists, with each list containing the indices of vertices that form a closed loop. From Will, "Plankton only handles manifold meshes, i.e. meshes which have a front and a back. This orientation is determined by the "right-hand rule" i.e. if the vertices of a face are ordered counter-clockwise then the face normal will be out of the page/screen."
# V: list of Point3d # F: tree of int
import Grasshopper appdata = Grasshopper.Folders.DefaultAssemblyFolder
import clr clr.AddReferenceToFileAndPath(appdata + "Plankton.dll")
import Plankton
pmesh = Plankton.PlanktonMesh()
for pt in V: pmesh.Vertices.Add(pt.X, pt.Y, pt.Z)
for face in F.Branches: face = list(face)[:-1] pmesh.Faces.AddFace(face)
These vertices and faces are precisely the output from Starling. Starling takes in a list of Polylines which form the (properly oriented) face loops.
The polyline face loops can be generated...
Directly from Panels on a surface using LunchBox
Using any network of lines/curves on a surface (curves will need to be converted to polylines before Starling)
The latter was achieved using the Surface Split command, then converting the face edges (converted to curves) into polyline loops to represent faces.

). It deals with the potential possibility to port GH into AEC fields (real-life AEC fields, nothing to do with academic thinking). The bad news are that the smart AEC sector is occupied solely by Bentley/GenComp – expect soon Revit/Dynamo as well (not to mention CATIA). The good news are that there’s millions of designers/engineers/industrial designers out there who could be interested for a 3rd alternative.
Intro: Well, in the old days (when men had mustache and muttonchops) AEC design performed in a nice top-to-bottom sequence (kinda like a vector) : the Big Man (aka The Brain) did some sketches (with crayons) and the rest (known as the “others”) struggled to make The Idea a reality. Today things are different, mind. Or they should be different. Or may be different. Or whatever. The big easy:For a zillion o reasons (AEC matures, PLM, cost, outsourcing, sustainable engineering…add several more) this vector like process of the past is like a Brown motion these days: Right down the moment that you (or your team) “sketch” The Big Idea … another team design simultaneously (i.e. in parallel) the components (parts) that compose the whole. This is the so called bottom-to-top design mentality. So the whole and the parts meet in some "middle point" instead the later being dictated by the former. In quite a few occasions parts dictate the whole (cost, cost and cost being the main reasons). The more a design is contemporary the more this bottom-to-top thing plays a critical role. Ignore it and have a very big time (sooner or later).The bad news:If you accept the above…well GH – at present phase - is not ready for contemporary AEC work. At.All.3 Main reasons for that:1.You can’t use parametric parts (i.e. nested blocks to speak Rhino language) into a given definition (in this case attached : truss nodes, connection flanges, mount plates, cable tensioners, planar glazing components, roof skin components…etc etc). This is obviously a Rhino domain.2.You can’t bake a given solution in such a way that the Rhino file is structured (i.e. assemblies of nested blocks). Or you can do it theoretically writing some VB/C code – but the core of the matter is that corresponding components are MIA. That means that you can’t export anything useful actually into established AEC oriented apps and/or established MCAD apps (for doing/calculating the parts for real-life production).3.The GH process can’t being interrupted. Imagine defining, say, a building “envelope” in GH and then …er…use Evolute tools in order to optimize things (say quad planarization and the likes). Then …continue in GH for more detailed work. Then design the parts as in 1 above. Then back to Evolute. Then back to GH.So…if anyone is interested I would be glad to start the mother of all debates and/or some kind of crusade (GH for President, that is).PS: This definition is a WIP thing – more refined stuff to follow (in particular a complex canopy tubes pre-stress system).
PS: Tree8 components are used sporadically.

io, alle ore 19:30 presso la Mediateca MARTE di Cava de’ Tirreni (Sa), la lecture magistralis dell’arch. Walter Nicolino dal titolo “Augmented visions / Responsive spaces”, un viaggio culturale che, attraversando gli studi progettuali a diverse scale condotti tra la sede torinese e il centro ricerca di Boston, mette in luce una attitudine nell’indagare e nel dar forma alle interazioni tra le persone, gli oggetti e gli spazi, al fine di fornire possibili risposte alle nuove istanze poste dalla rivoluzione digitale.
In apertura i saluti istituzionali del sindaco Marco Galdi, mentre a introdurre la lecture l’arch. Amleto Picerno, promotore del Mediterranean FabLab di Cava de’ Tirreni e tutor della Summer School digitalMed, il laboratorio progettuale che da quattro anni a questa parte, indaga temi, pratiche e tecniche dell’attuale panorama architettonico internazionale. È la smart city al centro della IV edizione di Summer School Digitalmed 2013, che si svolge a Salerno dal 22 al 28 luglio con l’obiettivo di creare un sistema di relazioni e di interazioni continue tra la città, le persone e l’ambiente in cui queste si rapportano in un continuo scambio di informazioni.
Ad esprimere la critic ai prototipi di progetto che emergeranno dal workshop digitalMed, sarà proprio Walter Nicolino, architetto di spicco del panorama italiano, coinvolto in numerosi progetti di ricerca al Senseable City Lab del MIT di Boston, insieme all’arch. Carlo Ratti con cui è fondatore e socio dello studio torinese CARLORATTIASSOCIATI.
Il 26 luglio lo space 1.0 della Mediateca MARTE di Cava de’ Tirreni si fa, dunque, arena d’avanguardia per un interessante dibattito durante il quale, a proposito della Summer School digitalMed, si ragionerà anche sul modo in cui le tecnologie digitali influenzano l’architettura.
«Da qualche tempo a questa parte possiamo scegliere se orientarci alla perfezione tramite navigatori GPS o perderci come sognanti flâneur metropolitani; possiamo associare in un batter d'occhio infiniti layers di dati a un luogo, oppure contemplarne in silenzio il paesaggio; possiamo anticipare la realtà con sofisticate rappresentazioni virtuali, oppure esercitarci in giocose autocostruzioni partecipate.
Possiamo avere l'una e l'altra cosa: non si tratta di una scelta tra il mondo reale e quello virtuale, come predetto da parte della letteratura agli albori dell’era digitale, ma si tratta di capire come il nostro ambiente costruito e gli spazi in cui viviamo stiano imparando a parlare un nuovo linguaggio e ad interagire in modo sempre maggiore con le persone - afferma Walter Nicolino che parafrasando Le Corbusier “La civilisation digitale cherche et trouvera son expression architecturale”, sottolinea l’importanza di integrare le nuove tecnologie e radici locali senza perdere la visione e la dimensione umana della città: All’architettura è richiesta una revisione dei propri strumenti per creare spazi flessibili, inclusivi, in grado di adattarsi ai nuovi modi di vivere e lavorare e di rispondere in modo interattivo alle nostre esigenze».

tly light vehicles such as bicycles and variations thereof. Although frame design is mostly of a structural nature, there are a number of elements that interact mechanically. Also, as you may be aware, bicycle and high grade tubing is not of constant section so shelling method in FEA is out of the question, but even so, because the joint needs to be modeled very accurately, that means different geometry and properties for welded area, heat affected area and base material; like so a simpler FEA package may not suffice.
I don't know karamba extensively, rather superficially, actually, but I'm under the impression it mostly deals with beam analysis. Pls correct me if I am under the wrong impression. I must say it would be very nice to have a complete FEA package inside GH really!!
Typical workflow for me would be to model everything in Solidworks, and then export to Ansys Mechanical. Although Ansys needs to read every input and naturally remesh back again, integration within Solidworks, Catia, Inventor, Creo, Solidthinking... and the sort, works reasonably well.
Now, I don't remember Ansys having a Rhinoceros plugin so that you could bridge the 2 together, but maybe I should go check again.
3) Great work with that fractal tree. It's nice to know it is a possibility at least. I have tried Apophysis and others, but to my knowledge there's not an application that could deliver 3D fractal designs in a way that you could further manipulate with conventional modelling techniques, maybe apply textures and render, or export to CAM, 3D printing... etc.
P.S.: I have tried all the apps mentioned above and then some more. All of them have serious limitations when it comes to parametric design. For complex models they crash plenty upon rebuilding... a number of time consuming errors appear, and general work flow isn't very efficient for purely parametric work. Speaking for myself, I'd rather spend the time on a definition that enables me to have full control and then generate a new result within seconds, than model everything very quickly and then taking a long time with each new result.
(Thanks for the replies and sorry for the long text, you asked to elaborate).…
