ted a picture of in your post. The reason is that sound has larger wavelengths than light.
With a light rendering model, energy can be said to reflect specularly, relative to their geometry, because the wavelength of light is inifinitesimally small relative to any object you might have modelled. With sound, energy may travel and reflect diffusely, or move around objects, depending on the scale of those objects. Think of the fundamental equation of frequency to wavelength - speed of sound = frequency X wavelength. Using that, you can see that a wave in the 125 hz octave is about as tall as a human being (or maybe a little taller) and would easily move around your body, not being reflected at all. A wave in the 1000 Hz. octave band is as big as your forearm, and might reflect specularly from your torso. A wave in the 4000 hz. octave band is about as long as your index finger, and might reflect off of your torso, or even your head.
Similarly, if you were to model the seats explicitly, it might be relatively accurate at very high frequencies (say 4000 hz. and above) but that is a very small part of the answer. Consensus in the field is that the most accurate way to model the seats is with a flat plane, raised to about shoulder height, and then with scattering coefficients applied to represent the varying effects of geometry on sound. I tend to use low coefficents below 250 hz. (say around 30%) and high coefficents above 250 Hz.(90%).
Absorption depends on the seat which was chosen. This is often a good area to use for a model calibration based on measured reverberation time.

ces are distorted (second). What is going on?
Surfaces in the second are a rhino cage edit of the surfaces in the first image. They were originally all closed polysrfs exploded just to input into grasshopper.
In the definition attached, each surface is compared to an original (its the small box in the far left of the top image) The point there is the ability to select for more than just the 6 faces of a cube, but find the closest match to more complicated inputs. In the second image, distorted surfaces are being compared to a distorted original.
If I have my math right, two parallel unitized normal vectors should have a dot product of 1, and the further away from 1 their dot product the further away from parallel, no? Why does it fail when I leave the comfy land of 90 degrees?…

e to constrains, I HAVE to do it like this (I can't 3D print everything or opposite).
First
I have no idea how to make the panels, without so many duplicate Edges, Faces etc.
Second
I can't figure out how to align the triangle panels to fit in the construction, so it can be assembled ideally without glue. This problem is both conceptual (I can't figure out how to do it fiscally) and grasshoper-wise - I don't know how to organize data list and produce a global movement, so that the triangle parts do not intersect with each other, BUT intersect the 3d printed construction part (where they fit fix in or just fit and can be glued).
Triangles will be milled out from 3mm Plexiglas, BUT I will not have an option to mill at an angle, so only 90° edges.
3D printed parts will be executed by a high level production powder printer, so it should hold good.
Any ideas?
best,
cuki

File) 2. I have designed a curved Trichordal-Truss from one curve in Rhino.
The Truss is lying in the XY direction and the footer is placed on the zero point.
3. And now my problem:
I want to put the Truss-object on the feet, move 90°
(from the XY axis to Z axis, see sketch 1).
4. Then copy / move the truss to all 36-points of ellipse (see sketch 1).
5. Align the 36 trusses with the center of the triangle .
pointing at the center of the ellipse (see sketch 2).
6. Using a slider to change the position of the 36-Trusses at der ellipse.
Variable distance between Truss and ellipse (see sketch 3).
Thanks for you Answer.
Best regards

multiply of variants from Galapagos, to have a chance for better analysis and comparability after. I also would like to use more then one solution in my design after.
In old topics i found kind of 3 solutions.
1.Change Galapagos to octopus ( what don t really want to do, i am kind of happy with Galapagos)
2. Use Slingshot! and MySQL Database ( it s look a little bit too complicated from the first view)
3. Use Colibri and Design Explorer Platform (looks kind of pretty way to solve my problem)
So i tried to add Colibri components to my definition , but have some mistake in the Colibri Aggregator after adding the Genome "An item with the same key already been added". I think it comes because for some steps i am using the "Gen Pool" and not a normal slider. Is it a way to connect Gen Pool and Colibri (i really prefer to have it, then a lot of sliders in some cases)?
And the second question (if i will get it solved with gen pool), could i somehow controll the recording process? For example i would likte to record only variants wit fitness over 90% or start recording just after 20. generation and record till the end?
I also opend for all other possibilities to reach the same goal (record/save/bake multiply variants from galapagos)

when i type the equations for z,y,z it says a syntax error so i obviously do not understand how to construct an expression. (screen capture attached)
Any help/explanation of using this function would be greatly appreciated
thanks so much

is useful to replace values (even if I cannot replace the same value for example "fraction radiant" in two different internal gains), but not to add new stuff, as in our case.
As you may recall, we were able to add our internal gains through the additional strings, but we have the problem of the default ones that we can not change or remove.
We've noticed that People, Lights and ElectricEquipment Internal gains are located inside the "runEnergySimulation" honeybee command inside the Python script.
We were thinking of two possible quick alternatives while waiting to be able to fully customize the internal gains with honeybee.
For the first one, if it is possible, you could make a "modified" "runEnergySimulation" command for us in which you cut off the Internal Gain parts, so that we can add them as text in the additional strings part. Alternatively you could show us where to add the additional strings we need inside the runEnergySimulation command so that we can add the values we need to run the simulation.
For clarity, these are the internal gains in idf file we need (that are inside de gh file in the panel just below the additional strings command)

not seem to manage to download the data... (see picture attached).Djordje, do you have any idea about what I can I do or check to fix this?
I just tried to run the component for a couple of locations and it successfully downloaded the data from opentopography.org:
When did you try to run the component? An hour ago?Can you try again?
Other question, just to be sure, regarding the "origin_", is it the central point that you to get out of the output mesh/surface? And does it need to be the point at the actual point elevation or does it need to be the point projected on the ground floor (as I do in my definition)?
Yes, you are correct about both things: it's the central point and it will lie on the actual terrain (it will be projected to the terrain).The latitude and longitude information from the _location input will be taken to find the origin_ point. Elevation will always be ignored, as elevation is calculated from the elevation of the point laying on the terrain at those particular latitude-longitude coordinates.Please let me know if I did not precisely gave the answer to your questions. Or if I misunderstood your question.We are here to help with any issue.…
' component in K2 works very well, it converged in equilibrium state. But, in K2E, the 'rod' component behave differently so it bend very much that the whole structure became collapsed. I was using the mechanical properties just as the K2E presets has provided.
Model from K2 after Solving
Model from K2E After Solving
I want to do structural analysis on my model using K2E. But, with the whole structure in an equilibrium state as it was reached in K2 component.
Do you have any idea how i should done this?
Should I have any input on the 'Threshold' part of the Solver in order to limit the iteration?
Any help will be much appreciated.
Thank you.…
