e and i get it. If you have time check the attached papers we published a while ago in relation to the contribution of thermal mass in the reduction of temperature in residential buildings. See the nice contribution of the heavy TM or the lower one for light TM.
As for the solarHeatCapacity, your description (of the 50W) is derived on a 1 Facade/Floor ratio and fully glazed. The only way to reduce it is to increase the ratio (bigger facade area). Which is not recommended (energy losses), but this is a different issue. So, roughly, we can say that 50 is the lower value. If i have less glazing area this number will be higher (right?)
I want to define a value list of "architectural situations", so it is easy to explain and understand. One situation can be:
"Ratio facade/floor 1 & Fully glazed" = 50
"Ratio facade/floor 1 & Half glazed" = 75
"Ratio facade/floor 1.5 & Fully glazed" = 30
"Ratio facade/floor 1.5 & Half glazed" = 50
"Ratio facade/floor 0.75 & Fully glazed" = 70
"Ratio facade/floor 0.75 & Half glazed" = 90
Makes sense for you something like this?
I also defined a value list for the timeConstant like this:
Light Building (Mobile home) = 1Medium-light building (Cement tiles on floor) = 4Semi Heavy Building (Concrete floor + Tiles) = 8Heavy Building (Concrete floors/ceilings + Heavy external and internal walls) = 12
As for the first 5-10 cm effective TM in general my assumption is that you take half of the mass to your space and half to the space above/below you. Will be interesting to do a parametric study on just the thermal mass, uninsulated and insulated to see what the depth limits effectivity will be. Interested in doing such a study together? Can be a nice work even for publishing.
Thanks a lot ... again,

In this case we see a geometrically approach, which doesn’t works efficient, because it required knowing how they behaviors together before, and I think it is not the ‘really behaves’.
To make the structure ‘really behaves’ I tried use kangaroo and the result works very well! As you can see I simply give the 2-set reverse UForce, and then they start to rotate until they found their equilibrium. That means 90 degree rotation. I was wondering what we can do to make a endless-rotation. I am mean 360 degree or more like this:
https://www.youtube.com/watch?v=4owFczeqqMQ
By the way, I try to give supports which allow a horizontal movement only (Just curious how we could keep the anchor-movement horizontally and in the same layer, for example like usual supports for compression ring…). I use the AnchorXYZ, but Kangaroo-Engine seems don’t accept its output.
So maybe some one knows a better solution?

problem later) to fit more shapes that are otherwise won't fit in.
On the example below horizontal rectangle couldn't fit in but its rotated analog could and thus was placed in.
Later, when placed shapes are used to generate frames, because of this rotation, the position of the starting points changes and because of the approach I use to generate the frames some angle values are attached to the wrong corners, this brakes the frame shape and looks like this (on the left the frame of sick shape and on the right the frame of the healthy shape):
Again, this happens because the angle values are assigned to the specific corners (points) and previously rotated shapes get these all messed up:
Easy fix, don't rotate the shapes, problem is, I've already baked a good number of them for later use. I'd like to avoid regeneration because it takes a lot of time and without rotation I constrict the algorithm even more.
Better fix, use a different approach, this is where I'd like to hear suggestions and kicks in a right direction. Please take a look at my definition. It works but I have a feeling like giving an amputee a job of sweeping the floor.

creating the structural frame, finding the endpoints, linking these endpoints with curves and afterwards lofting the surfaces between the curves.
The results were quite nice, however, the procedure is very time consuming and inefficient. There is just too much copy-pasting involved.
(see attached file: "Old Attempts.zip" )
Mesh relaxation:
I have later on used Daniel Piker's tutorials on Mesh Relaxation and realized that this might be the way to go.
The link to these online tutorials on wewanttolearn.net is:
https://wewanttolearn.wordpress.com/2011/10/22/mesh-relaxation-kangaroo-tutorial/
His tutorials, however, only deal with mesh boxes which are ideal cubes. He then joins them together in various directions, but it is under 90 degrees angle.
( see attached file: "Daniel Pikers Examples" )
What I would like to achieve:
I want my bridges to go in all directions and angles, not just under 90 degree angle.
Ideally I would like to make a square (polygon) follow a curve (which moves in all axis) at certain number of division points. I would then loft these squares into a mesh and use that shape as a mesh box. I would later use this mesh box and relax it the same way as Daniel Piker used the cubes in his tutorial. The anchor points are only the vertices of the squares which create the lofted mesh box.
( see attached file: "New Attempts" )
As you can see below this procedure works even if the curve is moving in all directions not only along xy axis. There are, however, many problems connected to it.
The problem:
Despite all the effort I cannot seem to come up with a design where I would be able to draw a random curve which would be the guideline for my mesh box and then apply this box to one definition in order to relax the mesh and create the shape that I want. Without this I am again forced into a lot of copy pasting as the final mesh box is made out of several sections.
Also is there any way I could make the final resulting mesh a bit smoother? Increasing the number of mesh faces is probably the only way, right?
Thank you guys so much for any potential help.
All best,
Luka

nd container id.Do you have the OpenFOAM container running?You can initiate OpenFOAM container by running start_OF.bat:C:\Program Files (x86)\ESI\OpenFOAM\1612\\Windows\Scripts\start_OF.bat
I have read other Issue problems such as #1 , #2 , #3 or OpenFoam Installation instructions but till now I couldn't run the simulation .. I figured out there is sth wrong with my openfoam installation where there should be a container called of-plusv1612-centos66 that openfoam must read it but it can not find it .. I checked with docker quickstart terminal as showed in pictures .. It could read the image but can not find the of-plusv1612 container ..
Do you have any suggestions?
P.S. I have opened all the possible files with or without administrator permissions but wasn't solved ..
Thanks …
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

een them to be adiabatic (at first. See later on for an alternative).
The whole process is fine/clear up to the solveAdjacencies: The walls are defined as "outdoors" and "surface" for the boundary conditions. So far so good.
Now i get to the HB_makeAdiabaticByType, and some issues appear (See A in the file).
Setting the interiorWalls to True doesn't change the condition from"surface" to "adiabatic" (A1 in file).
Setting the walls set both internal and external, to adiabatic (A2 in file). Is this supposed to work like this? Why the just the internal doesn't make the change?
In addition to this i'll appreciate your advice in the following. Let's say that i want the internal walls to be divided in 2 parts each. One should be adiabatic and the other "air wall". How do you recommend to do this? Is the modeling in the file correct, or i must do surface by surface?Or using the Decompose Honeybee Zone ...?
How can i retain the air walls and still use the makeAdiabaticByType component?
Thanks for your help!!

uired information, a poor representation of data evolve misreading messages and by turn ambiguous responses especially with complex data. Inforgraphics are graphic visual representations of information, data or knowledge intended to present complex information quickly and clearly. In the nowadays flow of complex information, Infographics is the key for optimized visual communication. The use of infographics is an important step towards developing a pedagogical approach that draws on visuals where 90% of Information is transmitted to the brain so it is crucial to tickle the optic nerves to get people excited about data. The workshop investigates how computational tools can aid in designing and controlling complex information to be easily understood in addition to improve cognition by utilizing graphics to enhance the human visual system’s ability to see patterns and trends and much more likely to be remembered in today’s fast – paced environment. This workshop investigates multiple computational tools and techniques of developing coefficient visualization of data types including; network, statistical and hierarchal data. The workshop objective is to reconsider visual representation a promising design tool for architects, artists and designers. /// Application To apply, please follow this link to fill the application form https://docs.google.com/forms/d/1HOv6c1_LzhHNJU5n_FLvuhC-Yg75HDfbEcq6TN6mulI/viewform /// Fees 1200 EGP for students / 1500 EGP for graduates and young professionals more info on the workshop webpage: http://www.encodestudio.net/#!infographics/cqvl
