orders from bottom to top. There are three pre-set heights: 20,000 / 50,000 / 80,000 (or 20, 50, 80 meters, I'm working in mm).
So if the three cantilevering volumes would be numbered 0,1 and 2, then I'm looking for a way to let Grasshopper generate the following:
A = 20m-position
B = 50m-position
C = 80m-position
(A,B,C):
0,1,2
0,2,1
1,0,2
1,2,0
2,0,1
2,1,0
Attached is wat I have so far, I have only managed to make simple translations per geometry.

summer because of the relative humidity of outdoor air will be over 80%.
I want to set the schedule like this
1) cooling setpoint to be 27C degree and max humidity to be 50%.
2) when the outdoor air temperature is lower than 27C, open the windows and ventilation naturally.
3) Air conditioning and dehumidification are needed only when the occupancies are at home (almost at night) and Natural ventilation is not to be.
4) Accept the indoor air relative humidity to be almost 100% when dry bulb temperature is lower than 27C.
Now, I set the air conditioning schedule as cooling setpoint schedule, but there are no components to set a dehumidification setpoint schedule.
The dehumidifier keeps working all day whichever the windows are opening or not.
How can I stop the dehumidifier during the windows open?
thank you.…
s, each made from two Nurbs curves, each with different surface properties.
Curves A1 and A2 have 2 control points:
startpoint and endpoint
Curves B1 and B2 on the other hand were drawn with 6 control points each.
What's more, those point's aren't equally distanced from one another.
The lofts inherit the position of control points of the profile curves.
The distribution of control points in the loft direction is uniform.
So no suprise here:
You can think of Nurbs curves as rubber bands and of Nurbs surfaces as rubber sheets. The areas with less control points would correspond to streched rubber.
Now lets imagine you take an A4 piece of rubber, lay in on a table and draw equally distanced lines on it. When you strech it ununiformally - the distances won't stay equal anymore.
Returning to your first post:
The Divide Surface component operates on u,v values which you can imagine as dimensions of the rubber sheet in relaxed state.
So the result you got was indeed an equaly divided surface, only in the so called "parameter space" of the surface, which doesn't always correspond to the xyz space.
There are methods to divide curves and surfaces in equal distances in the way you want it. For starters check out the Evaluate Lenght component.
I think that's enough teory for today. Have fun!

le discontinuous list of index numbers and I'd like to be able to generate a set of domains where each span of numbers would have its own domain. For example:
This list: 5,6,7,8,9,22,23,24,25,26,77,78,79,80,81...
Would give these domains: 5 to 9, 22 to 26, 77 to 81...
I'm at a loss as to how I can achieve this though. I know I can use the bounds function on the list but that would give a single domain, not several. In case it helps the list in question was generated by a true/false cull pattern from the complete list of indices so simply determining the indices of the beginning and end of each chunk of 'trues' in the cull pattern would work as well as it would give the same domains. I can post an example file if anyone would like but I figure this is a pretty general issue.
So anybody have any ideas on how to solve this multiple domains from a single list problem? Thanks in advance for any help at all, I'd really appreciate it!

e BIOS as i noticed that i was required to do so. This is the progress i made. Now the file "do something". It takes about 4 minutes in the blockMesh component, so something is happening. But at the end of the 4 minutes i get the same error as before. Tried to run the start_OF.bat externally, but no use either.
Those are the snapshots of both of them:
Be patient ... and bear with me. Sorry for bothering with this ... and thanks,
-A.
P.S. There is a chance it is related to the firewall of my university, or some other security issue for those trying to apply virtual machines/hosting.
I'll try at home in the evening.
A more detailed image of the shell running the batch file manually:
…
ce condition I believe, which yes usually this is 0. Bare in mind that OF divides pressure by density, so if you want the 'real' pressure you would need to multiply the results by 1.205 (perhaps we add this in BF at some point but it's easy in native GH).
Vector based velocity is a very good idea, and a nice and easy way to model these kind of flows!
If you wish to experiment even further with the custom boundary condition components you can try implementing a flowRateInletVelocity boundary condition (see https://github.com/OpenFOAM/OpenFOAM-3.0.x/blob/master/src/finiteVolume/fields/fvPatchFields/derived/flowRateInletVelocity/flowRateInletVelocityFvPatchVectorField.H)
It will allow you set the flows in m3/s, which is handy for usual HVAC specs. The direction of the patch follows the normal of the surface. Setting a minus in the volumetric flow rate assigns an opposite direction.
Thanks for using and sharing! Keep them coming!
Kind regards,
Theodore.
P.S.: Try this as an expirement. Increase the refinement of your mesh, factor of 4 should be nice. You can simply reduce the the blockMesh cell size by 4 to accomplish that. Try running the case and see the impact on the residual graph.

ters thesis on exactly stratification in atria and big semi-outdoor rooms.I am testing a bunch of variables and I was thus looking into utilizing Butterfly. However, this new update came too late in the process for me to fully test out.
I am very interested in your findings, as I had to go to the old fashion (and correct but yet very slow) way of using Ansys Fluent for my investigations.
I would however very much like to compare my results with the ways of the parametric tools, i.e. Butterfly: How valid are the results of BF so far? What could be optimized? When is the parametric tool favourable over the hardcore tools when considering these factors? What are the future objectives?
Could I therefore borrow your script later on at some point to use for my own to generate some analyses?Or would it maybe be possible for you to (in a month or so?) to create a very basic template script that is prepared for temperature analyses in an very simple atrium-like room maybe with an inlet and outlet as you are (or seem to be) making them? I am willing to go with NDA or give full credit to you and your work.
Very interesting what you are doing!!

llowing for higher skyline and construction areas along public transportation corridors. Up until now, neighborhoods once characterized by two-story houses, gardens and ground- floor open shopfront programs, have been completely transformed by the introduction of fortressed monolithic residential and office towers, which lack any sort of urban street life.
The new master-plan, however, now requires buildings to have an open street façade to accommodate multiple programs. Led by tutors from UNStudio (www.unstudio.com), the AA Visiting School São Paulo will address the changes being prescribed by the new masterplan through the redefinition of the tower typology in the extending of the ground of street culture, green landscapes and ecological mediation along the vertical axis of these buildings. For this, the workshop will teach advanced digital design and fabrication techniques to explore a series of novel differentiating structural and environmental organizations in the redefinition of the São Paulo skyscraper.
