http://grasshopperworkshopamman.blogspot.com/ introduction: This workshop will introduce basic and advanced notions of Grasshopper and the methodology of parametric design and algorithmic modeling and its usage in Architecture, design, landscape, and urban scale. It is intended for professionals and students with a minimum experience in 3D Modeling.

he resulting STL file has no problems. I was going to make a 3D print of it but I thought I could make it even more interesting.
When I make a duplicate piece of geometry with reversed curve rotation values and combine the 2 together I get this interesting result:
However, after baking this geometry the exported STL file has a huge number of errors - there are literally thousands of flipped normals, multiple mesh parts, and disconnected triangles.
I have tried lots of things to resolve this and none of them worked: converting to meshes in GH, GH mesh smooth, Rhino Solid Union, Mesh Repair, Align Normals, etc. I use 3D Builder to correct STL problems, but it can't fix this one.
An even more interesting shape happens when I twist the above shape in one direction, and then add it to another that is twisted in the opposite direction:
Of course the STL file for this one is even worse because it just compounds the previous problems.
Is there any way to resolve these problems? My GH file is somewhat messy and perhaps a bit obscure, but I'd be happy to clean it up and share it with anyone who thinks there is a way to get this puppy working.

of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

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 .

he "return" is comment out as shown below?
After restarting Rhino and Grasshopper, I opened the outdoors_airflow demo file, and the first step of creating the case file is ok:
Then the blockMesh component gives the following error: seems I have to manually start OF first..
so, as the error message suggested, I open OF by Start_OF.bat:
Then come back to the blockMesh component, now it can be executed while the OF command line window is also openning:
... and the blockMesh finished successfully:
... so I proceeded to run snappyHexMesh, checkMesh and update fvScheme:
... up to the simpleFoam component, I got the error again:
The warning message is:
1. Solution exception: --> OpenFOAM command Failed!#0 Foam::error::printStack(Foam::Ostream&) in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #1 Foam::sigFpe::sigHandler(int) in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #2 ? in "/lib64/libc.so.6" #3 double Foam::sumProd<double>(Foam::UList<double> const&, Foam::UList<double> const&) in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #4 Foam::PCG::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #5 Foam::GAMGSolver::solveCoarsestLevel(Foam::Field<double>&, Foam::Field<double> const&) const in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #6 Foam::GAMGSolver::Vcycle(Foam::PtrList<Foam::lduMatrix::smoother> const&, Foam::Field<double>&, Foam::Field<double> const&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::PtrList<Foam::Field<double> >&, Foam::PtrList<Foam::Field<double> >&, unsigned char) const in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #7 Foam::GAMGSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so" #8 Foam::fvMatrix<double>::solveSegregated(Foam::dictionary const&) in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/lib/libfiniteVolume.so" #9 Foam::fvMatrix<double>::solve(Foam::dictionary const&) in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #10 Foam::fvMatrix<double>::solve() in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #11 ? in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #12 __libc_start_main in "/lib64/libc.so.6" #13 ? in "/opt/OpenFOAM/OpenFOAM-v1606+/platforms/linux64GccDPInt32Opt/bin/simpleFoam"
... and the command lines in the readMe! output are pretty long and it is saved in the text file attached here.
So, my questions are:
1. why I have to manually start OF first before I can use the blockMesh component? Should butterfly automatically start OF?
2. what might be the cause of the unsuccessful run of simpleFoam in the end?
Hope you can kindly advise! Thank you!

len , I lost all of my work (at least the 3d modeling)
And I frankly if I want to participate I´ll need to finnish up the board and i cant do the renders on my own I need more time , but I only have until 11:59 pm of July 6 to finnish up one render, if you feel up to the challenge, whoever completes it will receive 290 dollars (its all I can give) to any account you want. I basically need one single image.
It consists on 3 towers, with an organic facade, I'm including the competition board I had saved on in my dropbox, I want more or less the same perspective shown on the left of the board.
Sorry, but i'm desperate, I had it all done but well cant control everything in life i guess, only do it if you feel you can pull off a professional render.
Thanks. (contact me and I´ll give you more info on the towers, I was able to save some limited sections and floor plans .... but yeah.. limited, so you´ll have to base your work on the images I provide here.
I can give some files now, including images of the physical model.
Board: http://i.minus.com/idYpFK844DWns.jpg
Physical model: http://imgur.com/a/PywJa
Hope its enough, I'm also including one image i had where I explored the footprints of all the buildings, but its just for reference.
I know theres barely enough time to finnish it... but I dont know what else to do, do you guys think i should probably just take a good photograph of the model and run with that? I feel that would probably look very unprofessional :l but I really dont have a choice here
