rep' to type 'System.Collections.Generic.IEnumerable`1[Rhino.Geometry.Brep]'. (line: 86)
This basically translates to: "I wanted a collection of Breps and you've given me a single brep". You'll need to put your cone and boundingbox into a collection. Easiest is to make an inline array:
Dim result As Brep() = Brep.CreateBooleanIntersection( _
New Brep() {cone}, _
New Brep() {boundingbox}, _
0.001)
I concur it should probably work on individual breps as well, I'll add those overloads to RhinoCommon.
-----------------------------
Dim volume As Double = rhino.geometry.VolumeMassProperties.Compute(result(0))
This is wrong. VolumeMassProperties.Compute() does not return a single number. It returns a new instance of the VolumeMassProperties class, which contains the volume, but also the error, the centroids, the moments of inertia and so on and so forth.
Dim vp As VolumeMassProperties = VolumeMassProperties.Compute(result(0))
A = vp.Volume

e inner face temperatures (from 4 to 6; at 4 is similar)
I checked this early on to cross-reference it with the comf map outputs, and that's what led me to suspect something weird may be going on with them.
When you once again omit the schedule, air change and system setting assignment part of our script, you get the below comf map results:
Comf map output of CMAP script with ideal air / OS system, schedule and ac/h script section bypassed
When you set the programme in the CMAP script to Office:OpenOffice, you get an similar output:
Comf map output of CMAP script with ideal air / OS system, schedule and ac/h script section included, with Office:OpenOffice programme set
Once I switch to the MidriseAppartment:Appartment programme, even with the ideal air / OS system parameters bypassed in the script, I get the following:
Comf map output of CMAP script with ideal air / OS system, schedule and ac/h script section included, with Appartment schedule set (same output whether ideal air part settings excluded or not).
Having stared at this "the men who stare at goats" style for quite some time now, I think I see the pattern now; the difference between the apartment and office programme is in the loads, etc. which mods the surf temps, which changes the distribution (and that one result you had that looked totally different did not reappear).
As for the 'wash' of temperatures- yes.. granted, the U value of the glazing is pretty good; the spread of temperatures we are looking at is only about 0.3 degrees, on average.
Maybe that simply *is* the distribution, and the E+ radiance temp output snapshot leads me down a false cognitive avenue, priming me to expect a different distribution than actually present?
Best,

xamine triangle AOC: OX bisects angle AOC.
3. Since we know the angle AOC (equal to A'O'C, which we can derive from the projector's known settings) we can also construct point O" (by intersecting two arches on any plane).
4. If we revolve this point (O") around segment AC we get a collection of possible locations of O
5. Repeat steps 2-4 for the other triangle (BOD) and we get the second possible set of locations (a circle revolving around DB
6. Intersect the two circles and we get O
I tested this and it works. However I'm still looking for a more elegant, solution. The best thing would be to do it all in a scripting component.…
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,

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.

s levels of detail by subdividing a 6 sided cube mesh and projecting its vertices according to a referenced height map. This is one of the standard conventions for building full sizes planets. At the lowest level (0) the mesh planet is made of 6 pieces(each 32x32 resolution). The next level down (1) is made of 24 pieces... 6 divided by 4 = 24. Level (2) is 96 quads etc etc. The script will generate each quad at its sub-division level and compare edge vertices to neighboring quads. It will then make sure any shared vertices are in fact at the same projected vector. This ensures a planet quad with edge vertices that match.
The problems comes in texturing each quad.
If I build the quad as a nurb surface from points I can place the texture easily because each surface UV maps squarely to my texture map (which is also square).
If I build the quad as a mesh I cannot just apply the square texture to the mesh UVs. This is because when you unwrap the UVs from a mesh they will not unwrap like a nurb surface's UVs. Therefore to get the correct mapping I would have to manipulate each UV back to an evenly aligned array (which is 1024 points in a 32x32 resolution UV). Maya and blender have 'relax uv' and 'align UV' functions but they don't do the trick and manual corrections are out of the question. So why not skip the mesh method and use the nurb method?
I did this and there is a trade off. The nurb will accept the material texture I want with no other work on my end but when I export the object as an .obj rhino creates its own mesh to describe the nurb(with various unsatisfactory setting options). This works great up to a point because at some level the interpreted mesh will have vertices that do no match at the edges, ie .. creating visible seams in the mesh. The picture below is the nearly seamless planet at LOD(1) made of 24 quads, each with 32x32 vertice resolution and a 512x512 jpg texture running in Unity3d 5. It works but at close level there are seams. This will be resolved simply by having the next LOD(x) instantiate before getting close enough to see the seam but at core nerd level I want the seamless mesh.
So, I can make the seamless mesh but I can not realistically texture map it. I can also make the nurb surface from points and texture it at the expense of the edge vertices matching. I am at the split in the road but I want to have my cake and eat it too. Thoughts, comments, trolls...?
Thanks for reading =)
Footnote: For you pros I am not using seamless noise across the map I am using grasshopper to sew up my otherwise non perfect edges.
