ere are ways to remap the data (PathMapper etc) and there's an excellent tutorial by David Rutten about path mapper on this forum somewhere.
And always look at whether you simply need to flatten your data to ba able to work with it.
For point lists I often use the PointNumber component to help visualise the data and the good old Panel component helps too!
When you see some of the elegant, compact definitions on here, there often seems to be some mystical foresight needed right from the first component but hopefully this jedi skill comes with practice!…

y does not account for contribution of shear to the total elastic energy, but it should be possible to get a shear force from equilibrium (much like with Euler-Bernoulli beams). The equation is something like this, using Einstein notation:
Mab,a+Qa=0 (1)
However, I don't know if the elements used in Karamba can deal with this? It would be very helpful to have information on shear forces in some cases...
Best,

operates, but why would you need 5 different simulations if you have 5 different thresholds? During one simulation can't Daysim switch between different slat states according to different thresholds of the external sensor?
Just to clarify with my Q1 above, I want the blind to be controlled by an external sensor with 5 different irradiance/illuminance thresholds, and measure the illuminance on a grid in the room to see the effects of the blind.
Anyone got anything to add to Q3? As I said any help is appreciated.
All the best

y using the Honeybee_Update Honeybee component.
The video below (best viewed in full-screen mode) provides an idea of what these components are capable of being used for:
The video below shows how these components can be used in an existing Honeybee project (for additional links please open this video in youtube):
I have uploaded two examples as Hydra files that show how these components can be used for grid-point and image-based simulations:
Example1 : Grid Point Calculations
Example2: Image based simulation
Finally, a more esoteric application is demonstrated in this video:
These components are still in the beta-testing stage. Some of the limitations of the components are:
1. Only Type C photometry IES files are supported at present.
2. Rhino is likely to get sluggish if there are too many luminaires (i.e. light fixtures) present in a scene.
3. Due to the spectral limitations of the ray-tracing software (RADIANCE), simulations involving color mixing might not be physically realizable.
Additional details about photometric and spectral calculations are probably an overkill for this forum. However, I'd be glad to answer any related questions. Please report any bugs or request new features either on this forum or on Github.
Mostapha, Leland Curtis, Reinhardt Swart and Dr. Richard Mistrick provided valuable inputs during the development of these components.
Thanks,
Sarith
Update 16th January 2017:
An example with some new components and bug fixes since the initial release announcement can be found here

s, each made from two Nurbs curves, each with different surface properties.
Curves A1 and A2 have 2 control points:
startpoint and endpoint
Curves B1 and B2 on the other hand were drawn with 6 control points each.
What's more, those point's aren't equally distanced from one another.
The lofts inherit the position of control points of the profile curves.
The distribution of control points in the loft direction is uniform.
So no suprise here:
You can think of Nurbs curves as rubber bands and of Nurbs surfaces as rubber sheets. The areas with less control points would correspond to streched rubber.
Now lets imagine you take an A4 piece of rubber, lay in on a table and draw equally distanced lines on it. When you strech it ununiformally - the distances won't stay equal anymore.
Returning to your first post:
The Divide Surface component operates on u,v values which you can imagine as dimensions of the rubber sheet in relaxed state.
So the result you got was indeed an equaly divided surface, only in the so called "parameter space" of the surface, which doesn't always correspond to the xyz space.
There are methods to divide curves and surfaces in equal distances in the way you want it. For starters check out the Evaluate Lenght component.
I think that's enough teory for today. Have fun!

limate based sky, and then use that sky to do a radiation analysis with ambient calculations turned off (i.e. a -ab 0 run).
Daysim approximates the position of the sun, which can be in as many as unique 3000 locations on an annual basis, to only 65 odd locations in the sky. GencumulativeSky, which is used for the cumulative studies in the Hydra examples, takes the annual radiation data and creates a Tregenza Sky pattern .... While a Tregenza pattern might be fine for an annual simulation, using it for hourly simulations isn't going to be very accurate.
There are actually some thermal comfort examples on the Hydra website that you might find useful.
