Angeles, which has 12% of the year made comfortable, and Shiraz, Iran, which also has 12% comfortable (assuming default parameters).
Jerusalem also makes sense to me. There is only a maximum possible 9% of the year that is inside the polygon (you'll see this if you set the timeConstant to a very high number). The default strategyPar makes 6% of these hours comfortable and 3% without cool enough temperatures in the previous hours. This seems reasonable to me.
I could be convinced to change the default time constant to 12 hours (instead of 8) as I know that 12 is the default of climate consultant but that seemed really idealized in my opinion. You'll need really high exposed mass and insulation without much internal heat gain to make conditions stable for more than 8 hours in my opinion.
As for the solarHeatCapacity, I get changes when I drop it down to 10 W/m2 or boost it up to 100 W/m2. It's definitely a parameter that operates on an "order of magnitude" scale and little tweaks to it won't change it too much. You can think of this number as representative of a lot of other physical properties: most notably the depth of the space being passively heated and the thermal mass of that space's materials that participate in heat exchange over the time constant. Climate consultant uses a default assumption of 30 W/m2 but, from my calculations, this is likely assuming a space that has a facade to floor area ratio that is greater than 1. If we say that we need to raise the temperature of 10 cm of an exposed concrete floor for passive heating purposes, and we have a facade-to-floor area ratio of 1:
Required solar flux = ((1 facade-to-floor ratio) x (0.1 m3 of concrete) x (2400 kg/m3 concrete density) x (880 J/kg-K concrete specific heat capacity)) / 3600 seconds/hour
This lands you with a required solar flux of 58 W, which is almost twice the 30 W climate consultant default. While me might say that not all 10 cm of concrete participates over the course of a default 8-hour time constant (most of the action is probably within the first 5 cm), we also have to account for things like transmittance of solar though the window, which, for triple pane, is probably only half of the incident solar. So 50 W seemed to be a more reasonable rule of thumb from my perspective, essentially assuming a facade-to-floor ratio of roughly 1 with 5 cm of concrete participating in an 8 hour heat exchange and a little more than half of solar heat getting through a fully glazed window.
Let me know if that makes sense or if you have any suggestions,

hat will be the basis of creating lamella members. In the sketch I'll use the 8 m side as U and 6 m as V. The surface is divided into a grid comprised of 1 m² squares. This step is not strictly needed but I use it to calculate the spacing in each direction for trimming.
2. Remap the UV of the surface again to generate the grid for lamella members in each direction. This grid subdivisions will be twice the size of the basic grid from step 1. Before remapping the grid I'm pretty sure I trimmed off the ends of the surface in the U direction by 1/2 the grid division distance (1 m off each end in the sketch). Repeat this for V, but in the other direction.
3. Extract the diagonals in each of the grids from step 2. Connect points 0 & 2 to form on diagonal, and 1 & 3 for the other diagonal. This will create lines for generating the lamella ribs. You'll have to dig around my definition to see how that's done...it will be very difficult for me to type that out.
4. Others probably have cleaner methods of producing the same effect. I know I certainly didn't put much effort into cleaning up the definition.

o sensor Shield V5.0 - 2 standard servos (plugged into pins 9 and 10 in the sensor shield) - 7.5V wall power supply - USB cable to computer
I'm running Rhino SR 8 on a 32 bit Windows Vista machine I have Version 0.9.0014 of grasshopper (the latest) and Firefly_Build_1.0067 I have flashed my Arduino board with the latest firefly firmata (updated September 10th, 2012)
I have checked that I am using the "MEGA write" box I have got the right bits going to the right pins and I have checked that they all have "servo" ticked instead of "digital" or "pwm"
My servos and board work perfectly well with the normal Arduino software, but just not any longer with firefly since my computer was switched off.
The port shows correctly as COM 4 and opens fine.
When I move the slider to control the servos, the TX light is on and the RX light flashes, but no servos move... (everything works with the sweep example in arduino though, so I have eliminated power and wiring issues)...
Any ideas what might be the problem?
I've tried re-installing, switching off and on many times, changing cables, trying a different board (also doesn't work any more with the duemilanove), trying all pins on the shield, trying one servo without the shield, trying one servo with the shield, lots of googling, lots of searching forums, unblocking the firefly installation files in explorer, lots of things... I'm all out of ideas... And very confused as it was working just a few days ago... Am I just missing something really obvious or could there be an issue with the software at my end?…
rom a few pieces until all of the pieces are in place. You could also, theoretically, modify the form of the base, high, etc.
To do this I started making three pieces (all triangular) of different sizes... and then I stablished that there is going to be a bigger concentration of bigger pieces on the first third of the building, a bigger concentration of medium pieces on the second third and a bigger concentration of small pieces on the last third. I did this by rotating the pieces a number of times accordingly to a percentage.. the funny thing is that it works most of the times, but it doesn't work if the base of the building has 3, 8, 12, 18 or 20 sides (20 being the higher number on the number slider).. maybe there is a way to solve this with lists that I am not using????
My second problem is that I want to rotate each floor of the building separetly using a range... the thing is, I cannot make it work, because it rotates each triangle and not the whole floor... maybe there is a way of making groups or changing the list definition, but I'm not getting there.... I tried working with planes, but it is even more difficult to make the whole thing work...
I'm attaching the grasshopper documment and a couple of pictures so you can get my idea....…
basis FE model to get some stresses to evaluate and then I remap these stresses into a thickness within a certain domain. These values are then used as input to a new FE model.
I look at a cantilever beam (8 x 3 m) which has uniformly distributed loads on top and bottom and all DOF's are fixed in the end (left side).
I get the exact opposite result as I would expect. See the result below.
I've tried to switch the domain input of the thickness which kind of gives a result more likely to what I would expect but still does some weird thing at the end of the cantilever beam. Also I don't really see the logic in doing that.
I've also tried the region boundary support instead but with no luck.
Can anyone see what I'm doing wrong?
Thank you very much!…
control point edit from a sphere.
Since it is the first time I try Exoskeleton, I checked the lists of input geometry in the exemple and got the same in my definition, but the component turned red, giving this error message:
1. Solution exception:Index was outside the bounds of the array.
For the Radius at Start and End values, I tried using the same principle applied inside the Exo-vase exemple, which links the radius to the Z values, remapping them from .3 to 8.
Is there the problem or elsewhere?
Could someone give me a hint about what I am missing ? Many thanks!!!
Below a screenshot., and I attach the definition.

ou will see all of the available components on a ribbon at once so there is no need to keep clicking drop down menus.
It's all about discoverability with GH. What if you're a beginner and don't know about the Create Facility (dbl click canvas) how can you find Extr?
Even if you hover over every component or use the drop down lists you will not see the name Extr appear anywhere.
Sure it makes sense that Extr is short for Extrude but it's also the Nick Name of Extrude to Point component
So you can easily miss the fact that one has a Distance Input verses a Point Input.
I think I made the move to Icons around about the move from version 0.5 to 0.6, possibly before. I initially thought that I would go back to text because I loved the mono chromatic look of the text but I soon realised that Icons were the way forward. The greatest benefit is speed. You don't need to digest and decipher every component (which is written 90 degrees to the norm).
I'm not saying you should move to Icons forthwith but at least consider that once you have a better knowledge and understanding of GH, Icons will set you free.
My top ten tips that I would highly recommend to anyone wanting to better themselves with GH.
1) Turn on Draw Icons
2) Turn on Draw Fancy Wires
3) Turn on Obscure Components
4) Use the Create Facility like a Command Line eg "Slider=-1<0.75<2" or "Shiftlist=-1"
5) Use Component Aliases to customise your use of the Create Facility eg giving the Point XYZ component an alias of XYZ will bring it up as the first option on the Create Facility as opposed to the other possibilities.
6) Try to answer other people's questions even if it's not relevant to your own area. By looking into solving a problem outside of your comfort zone and then posting your results it is very rewarding but it also lets you see the other approaches that get posted in a new light.
7) Take the time to understand Data/Path structures.
8) Buy a second monitor - There is nothing that can compare to real estate when working in Grasshopper.
9) Read Rajaa Issa's Essential Mathematics
10) Pick a panel in a tab on the ribbon and get to know every component inside and out and then move on. Start with the Sets Tab > List Panel…
