roader than this. IFC (Industry Foundation Class) as an open BIM format permits users with the choice of other software they work with. From Grasshopper you can choice to use the model data in Digital Project, Archicad, Microstation, Tekla and beyond. http://buildingsmart-tech.org/implementation/implementations
But there is much scope for improvements in the implementation of model importing/exporting in all software. This is also why I decided to develop a Revit Addon (I can reuse 80 to 90% of my existing c# code) to import the data within this environment. But again this enabling workflows from all the software above plus Rhino/Grasshopper into Revit.
Certainly I think the work of the others is impressive and in areas I haven't really broached yet. But given demand for these aspects I will certainly be looking at it.
Look forward to hearing other thoughts and observations.

temperature.
I changed it and things are clearer, yet now I became intrigued by a discrepancy between what is reported by the "conditionOfPerson" and the "percentOfTimeComfortable" outputs. At first glance would seem that they are reporting the same thing in different manner, but they both provide different outcomes (See pic).
Why is that the case?
Shouldn´t the "conditionOfPerson" output had to incorporate the values within the threshold of 80 or 90% (in case that is not happening)?
Any comments?...
PD: The AdaptiveComfortChart doesn´t provide any output data. Not that I wan´t to rush any one out to fix it, but I just want to report it.
Thanks!,
Alejandro

s random reduced with the random reduce component.
Then the random reduced surfaces, is extruded in z direction with negative factor, The plane surface is also extruded in z direction with negative factor, then i used Trim solid, and had about 40 boxes cut in the xy plane with different hight.( hight is from the flowing surface)
The i open a new grasshopper file, and take brep container, and get one of the boxes cut in xy plane, but if i use isotrim on the brep faces or subdivede quad from lunchbox, the divide component show orginal extruded surface and not the smaller one i got after using Trim solid, on the extrusion.
is it clear or you need the file, and have anyone a answer
thank you

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.…
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!!
