t the elements I used CreateHBsrfs and I added "Adiabatic" in the EPBC input. Since the EnergyPlus results weren't what I expected, I checked the idf file and I discovered none of the element is adiabatic. Furthermore, the simulation doesn't use the materials I set up for the not-adiabatic wall.
I even tryed with MakeAdiabatic, MakeAdiabaticbyname and MakeAdiabaticbytype. With the first and second the problem is still the same. With MakeAdiabaticbyType, if I change one wall type in the CreateHBsrfs, it still remains the same type in EnergyPlus, so it makes all the walls adiabatic. Is there something I can do? I attach the GH file Thanks in advance Lisa…

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.

ns. but first allow me to explain what i'm trying to do: i have a serial device i want to talk to, but i have to do it using some sort of handshaking. for instance, when i send a command/data, i need to wait for an appropriate response before sending another. i have used andy payne's general serial components from firefly, but i don't think they'll work for what i want to do, and in general, i want to know how to do this from scratch. i'm using the pyserial library to do the comm, and i can get it to work within one script. here's an example of a working (mostly) port open/close script (x=input param for baud, y=input param for port name, z=boolean input param for open/close):
import serialmyPort=serial.Serial()myPort.baudrate = xmyPort.port = yif z == True: try: myPort.open() except: print "Something went wrong. Cannot open port." if myPort.isOpen() == True: print myPort.name + " is open" if z != True: try: myPort.close() except: print "Something went wrong. Cannot close port." if myPort.isOpen != True: print myPort.name + " is closed"
this all works well and good. here are my questions:
1) I can open the port and then close it. however, if i try to re-open it, i get an access denied error. it seems rhino is holding the port open, as i have to re-start rhino to get it working again. i read through the discussions and didn't see any definitive answers to this problem. any advice?
2) I'd like to share this port with other components (or at least break up the functions of opening/closing the port and read/write, not unlike how the firefly components are organized), but i have no idea how to share an object instance between components. i did see that there is a sticky dict and tried to add myPort to it, but i kept getting errors in the other component when i try to use the object's methods. for instance:
Component 1 Script:
import serial
import scriptcontext
myPort=serial.Serial("COM4", 9600)
scriptcontext.sticky['myPort']=myPort
Component 2 Script:
import serial
import scriptcontext
myPort=scriptcontext.sticky['myPort']
print myPort.read()
but i get messages like:
Runtime error (MissingMemberException): 'Serial' object has no attribute '_port_handle'
any assistance would be greatly appreciated!!

starting mesh. The geometry of the lines is then modified, through the formfinding routine.
In my second vb component, I need to build an array with 4 columns. Each row represent one face of the mesh (row 0 for face 0, row1 for face 1, ...) and each column represent the number of the edge element. If ABCD is the quad face, column 0 is the number of the edge AB, column 1 is BC, column 2 is CD and column 3 is DA.
So to build this array, I extract the edges of each face with FaceB component then Explode component, and I build the array by comparing each line coming from this to each line coming from MEdges component, with a 2 level nested loop. Here is where I am looking for an efficient way to compare 2 lines...
Is there an easier and faster way to build this array ?…

But with my script, I canot align the center of gravity with the center of buoyancy longitudinally.
What I would like to do is to have 3 inputs:
- Heel angle (Degrees)
- Displacement (Tons)
- Center of gravity position of the ship (X, Y, Z)
And the script acts on the hull depth (like now) AND on the trim angle, so the GC and BC can be aliged longitudinally.
Anobody has an idea ?
