nd linear/planar tectonics. Within this new field of investigation, the Stuttgart VS will be researching into novel techniques of material mixtures and grading, associative design and double curvature surface generation.
For the second cycle of this exploration we will be based at the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart. Drawing from the Institute’s long history of experimentation and research on tensile structures instigated by Frei Otto in the 1960s and conducted at present by Werner Sobek, this year we will be focusing on the design and fabrication of materially graded membranes, as well as the application of UHPC and FGC on fabric formworks. The workflow followed will be divided into two stages:
1. Computing Membranes: Computational form finding methods will be taught by professional engineers and architects from ILEK and str.ucture GmbH. The aim will be to utilise the latest software technologies to form find membranes for textile structures, or fabric formworks for complex concrete structures. The results will be evaluated against criteria such as internal air pressure, as well as asymmetric and wind loading. The outcome of this research will inform the material grading procedures (i.e. changing the stiffness, thickness or porosity of the membranes themselves, or the consistency of the concrete poured into the formworks) that will follow in stage two.
2. Fabricated Grading: The digitally computed membranes or formworks will eventually be fabricated physically, utilising the workshop and robotic fabrication facilities at ILEK. The objective will be to rethink conventional research on tensile and concrete structures as isotropic constructs, by customising attributes such as materiality, reinforcement, rigidity, translucency, patterning, and porosity among others. The final, graded prototypes will be made up of mixtures of materials, all accurately engineered to respond to variable environmental, structural and aesthetic criteria, in essence forming multi-material structures that have finally caught up with the latest material developments.

even (0, 2, 4) then that means the point either never hit it, or went in and out again, meaning it's outside. If it hits an odd number of times, then it must have come from within originally.
The method implements this approach using the mesh bounding box, and then striking a polyline from your test point along a vector that is defined by the upper right corner of the bounding box + a vector of (100,100,100). In the case of your failing points, this is a result of their striking an edge very precisely, which gets counted as 2 hits instead of 1 (as it should be getting captured) and passing false:
Your best bet is probably to roll your own implementation, that tests for multiple vectors:
private void RunScript(List<Point3d> P, Mesh M, ref object A, ref object B, ref object C) {
BoundingBox bb = M.GetBoundingBox(false);
List<bool> inside = new List<bool>();
for (int i = 0; i < P.Count; i++) {
Polyline a = new Polyline(); Polyline b = new Polyline();
a.Add(P[i]); b.Add(P[i]);
a.Add(bb.Max + new Vector3d(100, 100, 100)); b.Add(bb.Max + new Vector3d(100, 150, 150));
int[] fa; int[] fb;
Point3d[] xa = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(a), out fa); Point3d[] xb = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(b), out fb);
inside.Add(xa.Length % 2 == 1 || xb.Length % 2 == 1);
checkA.AddRange(xa, new GH_Path(i)); checkB.AddRange(xb, new GH_Path(i));
}
A = inside;

This is the change that I made to your simulation.
It's usually not a good idea to have space in the path, as you do for "Projeto de Pesquisa", when dealing with Radiance.
cc: Mostapha/Chris. The culprit is the octree resolution setting of 2048. I guess most users won't run into issues with that kind of setting. So, I am not sure if a fix is needed for this at all.

izes like 0.6m, 0.8m, 0.9m and 1.2m are the most "common": In cases where mechanical floors are a must (hospitals for instance) a 2.4/2.4 is quite handy (habitable/mechanical per floor). You can try 1.8/2.7 as well (floor/habitable) since 1.8 floor thickness can host HVAC and some decent W truss size. Also 1.6/2.4 (floor/habitable) is used in small buildings. NOTE: see next.
3. Don't forget to include corrugated metal height + concrete screed height + raised floors height: for the latter, say, something like 0.3m (modules + adjustable mounts + free space for electric stuff [boxes etc]).

ybee_EnergyPlus Window Shade Generator" component.
3. SolveAdj component has the input to set BC for interior surfaces.
If you want to set them to adiabatic then you can use setToAdiabatic components.
4. For natural ventilation Chris has provided extensive answers including this one.
If the component doesn't work then you need to download the files manually from github and replace the userObjects with the old ones. You have to do it separately for Ladybug and Honeybee which can be painful. Is there anyway to change the firewall settings?

till quite rough.
I went through your attached log but it seems to be a successful run, perhaps the error log wasn't attached. In any case, I believe we have identified this issue. The goal of the update fvSchemes component was to apply schemes to finalized meshes in an automatic way. While this is useful for new users it is also a dangerous thing to do in CFD studies.
The component works by relating mesh quality to the mesh non-orthogonality, which the checkMesh component reports. While non-orthogonality is one of the important criteria of mesh quality it does present difficulties on some kind of meshes, especially like the simple cases that BF has been meshing so far.
The example case of simple box buildings in a wind tunnel above for instance will appear as a good quality case for even the lowest of cell-count meshes, simply because it is an orthogonal geometry. That means that checkMesh will probably report low values (imagine an empty blockMesh of 10m blocks has a non-orthogonality of 0) which in turn means that higher order schemes might be paired with actually low quality meshes. This I believe is causing problems.
I posted a possible solution to this here https://github.com/mostaphaRoudsari/Butterfly/issues/57. The idea is that Buttefly provides additional options to the users, enabling them to choose between first-order (faster, more robust, but lower quality schemes) and second-order (slower, less robust, but more accurate) schemes depending on mesh quality, stage of assessment, etc. In cases like the above mesh quality a first-order scheme might provide a better option. To test this I am attaching an fvSchemes file you can use by replacing yours in the /system folder of the case.
As a note however, I would like to stress there is so much that a tool like Butterfly can provide in this area. Meshing is a quite complicated and demanding part of the process, involving a lot of trial and error. Sometimes the problem is just the mesh and not the solution options (GIGO stands true in CFD as well). It does however get easier with experience. The safe advice is the simplest one: when changing solution options doesn't help, refine mesh and run again.
Kind regards,

stall with Visual Studio Express, which is something that I highly recommend doing.
As far as a basic guide, I think most of the beginners books that are out there are going to cover the topics that are going to be used within Rhino/GH fairly well. On one hand, the books out there are all pretty decent, but its more that programming with GH doesn't really require using all of the features of dot NET. As long as you get things about syntax, flow statements, data types, an introduction to OOP, and coverage of using collections, they you'll be fine in regards to programming in GH.
The one that I have here, which is useful but not a stand out, is Beginning VB.NET. I've liked Apress recently, so their book Beginning VB 2008 might be worth a look. I have the O'Reily book VBscript in a nutshell, which is leans more towards reference with a good introduction. Although I can't say with certainly, their VB 2005 in a nutshell book seams to be along the same lines.
Also, I've yet to find a book that is very relevant to Rhino/GH or doesn't have a bunch of stuff that winds up going largely unused in the context of Rhino/GH. Its not that those topics are useless (they might be if you choose to take your programming in a more "typical" direction), but within Rhino/GH they just don't get much face time. The topics that are useful will always require some translation as well, since the examples use some generic kind of issue to demonstrate the topic at hand.
Lastly, I've gotten more mileage out of books that are more specific than the general ones, so if there are some specific issue that you think you might want to explore you might want to see if there's a book out there that's more useful. Since I think OOP is a important concept to grasp to program well with the SDK, I'd take a look at Beginning Object Oriented Programming as its been a very useful book for me.…

r even a geometry.
We want to develop open source architecture, and be able to reuse easily open source elements of projects shared by the community.
We are interested to display the 3D files in the browser, thanks to connection with external services like http://beta.speckle.xyz or others though at the moment it is not yet available.
When I discovered the grasshoper forum, I liked the fact that people talk very openly about their modelling problems and share definition files...
But I think Bricks could be a complementary publication mode, to find in a glance an element with all its geometry and a link back to the forum post to join the discussion.
Indeed when I work as an architect, I have not always the time to browse a forum with all its discussions to find a suitable element for my project.
I've quickly reposted 2-3 forums posts to test it out.
I would love to have your feedbacks on this new way of publishing grasshoper definition files and more globally 3d reusable geometries.
Here you can see a single definition or the list of definitions that can be classified at the left thanks to custom categories.
If you create an account and upload a few definitions and 3d images and files, you could also tell us, what you think of this process.
