used of 180 being for the northern hemisphere and 0 for the southern hemisphere.For the optimal tilt, to my knowledge, they are mostly based on correcting location's latitude through a single formula.TOF component is more sophisticated. It essentially replicates the Solmetric's Annual Insolation Lookup tool.What it does is that it creates a grid of points. Each point represents the calculated annual insolation on the surface (PV module, SWH collector, facade, any kind of surface) for a single tilt and azimuth angle.Each point is then elevated according to the annual insolation values. The mesh is created from that grid of points. The portion of the mesh which is the highest, represents the optimal tilt and azimuth angles. So the higher your "precision_" input is, the more points in a mesh you'll have - thus the more precise final optimal tilt and azimuth will be.For the diffuse component of the annual incident solar radiation for each point the Perez 1990 modified model is used. Direct is from classical cosine law, and Ground reflected component from Liu and Jordan (1963).So TOF component calculates the optimal tilt and azimuth based on annual incident solar radiation, not AC energy....…
the use of digital technologies as architectural design tools. The workshop " Computer Aided Design: parametric design and digital fabrication " aims to do some introductory teaching in the use of some of these tools.
The workshop will focus on the use of computational models of parametric behavior for generating architectural forms. The generative capacity of these models it will be tested in the development of designs defined by repetitive non-standard components, based on the parametric control of its variations and series differentiations. This process will be developed by the use of a three-dimensional modeling software - Rhinoceros, associated with an application for visual programming - Grasshopper.
The last day of the workshop is dedicated to the use of digital manufacturing tools in architecture. Part of the work will take place at the facilities of the Institute of Design of Guimarães (IDEGUI) providing for the use of their laboratories and manufacturing CNC machines (computer numerically controlled).
At the end of the workshop, it is intended the students to understand that the use of digital technologies in architecture can overcome representational functions, and their integration in the design conception, analysis and construction enriches the methodology of project development.

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!

1. Select a building to mount a photovoltaic generator on (seen in Rhino in green).
2. Select a surface within that building to mount a photovoltaic generator on (seen in Rhino in green).
3. Create a Honeybee context surface from that surface.
4. Place a photovoltaic generator on that Honeybee context surface by using the Honeybee generation component. Honeybee_Generator_PV and connecting the context surface to it's input _HBSurfaces. Then you can specify both the performance and the financial data of the photovoltaic generator.
5. Create a Honeybee generation system which consists of the photovoltaic generator in 4. By using the component Honeybee_generationsystem and connecting 4 to its input PVHBSurfaces_. Then you can specify the annual maintenance cost of this system.
6. Run the simulation in Energy Plus by connecting 5. to the input HBGenerators_.
7. Read the results of the simulation:
- The electricity produced by the Honeybee generation system in 5.
- The net purchased electricity of the facility (the Honeybee zone) to which the Honeybee generation system is attached to. This is the electricity consumed by the facility less the electricity generated by the Honeybee generation system.
- The financial costs of the Honeybee generation system; capital, maintenance and replacement costs.
8. Calculate the net present cost of the Honeybee generation system in 5 assuming a 25 year lifetime.
9. Visualise the net present cost.

e is changed.
This is what I am trying to achieve: If the dropdown component is changed, the c#-component should update the slider... It is also working with GH_Document.SolutionEnd Event but as far as I understand, this will recompute the whole solution. So if there is a huge script following downstream, this will be called always twice (correct?). I would like the script to:
1. detected the change of an input parameter value 2. stop the script and set a few sliders 3. continue computing downstream stuff.
Thanks in advance!
private void RunScript(System.Object mySliders, bool startme, ref object A) { if (!startme) return;
if (_running) return;
_run = true;
Component.Params.ParameterChanged += new GH_ComponentParamServer.ParameterChangedEventHandler(OnSolutionEnd);
}
// <Custom additional code> private bool _run = false; private bool _running = false;
private void OnSolutionEnd(object sender, GH_ParamServerEventArgs e) { // Unregister the event, we don't want to get called again. Component.Params.ParameterChanged -= OnSolutionEnd;
// If we're not supposed to run, abort now. if (!_run) return;
// If we're already running, abort now. if (_running) return;
// Reset run and running states. _run = false; _running = true;
foreach (IGH_DocumentObject obj in GrasshopperDocument.Objects) { if(obj is Grasshopper.Kernel.Special.GH_NumberSlider) { var slider = obj as Grasshopper.Kernel.Special.GH_NumberSlider; slider.TickValue = 9; _running = false; } } }

radiance parameters to get rid of blotching. To add another level of complexity to my problem, I am running simulations with a translucent material with the following properties: void trans testTrans
0
0
7 0.478 0.478 0.478 0.000 0.010 0.178 0.635
I have had no issues with the renderings when I use clear glazing, as seen on this image:
However the blotching-issue becomes very noticeable when I introduce translucent glazing into the scene:
For the two above cases I used the following parameters:
_av_ is set to 0
xScale is set to 2
_ab_ is set to 6
_dc_ is set to 0.5
_aa_ is set to 0.2
_ad_ is set to 2048
_st_ is set to 0.5
yScale is set to 2
_ps_ is set to 4
_ar_ is set to 64
_as_ is set to 2048
_ds_ is set to 0.25
_pt_ is set to 0.1
_dr_ is set to 1
_pj_ is set to 0.9
_dp_ is set to 256
_dt_ is set to 0.25
_lr_ is set to 6
_dj_ is set to 0.5
_lw_ is set to 0.01
I ran another test with increased Radiance parameters and got the following output:
with the following parameters:
_av_ is set to 0
xScale is set to 6
_ab_ is set to 6
_dc_ is set to 0.75
_aa_ is set to 0.1
_ad_ is set to 4096
_st_ is set to 0.15
yScale is set to 6
_ps_ is set to 2
_ar_ is set to 128
_as_ is set to 4096
_ds_ is set to 0.05
_pt_ is set to 0.05
_dr_ is set to 3
_pj_ is set to 0.9
_dp_ is set to 512
_dt_ is set to 0.15
_lr_ is set to 8
_dj_ is set to 0.7
_lw_ is set to 0.005
Although the second blotching case is much better than the first, it is still very bad for hours when the sun is lower in the sky. The above images are rendered for a clear sky at 18:00 in Germany in a West-facing room.
Sorry for the long post! Can someone help? Kind regards, Örn
