f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance

akes the linear regression of the Schroeder integral over 30 dB worth of decay. Whether it is T-15 or T-30, they all seek to estimate the RT, which is always always the time it takes for sound to decay 60 decibels.
The website has benchmarks, for your reference. You can find them under the 'Pachyderm' drop down menu, under 'Benchmarks'.
Your model may well require millions of rays to be accurate. It sounds like a very large space. I'm sorry if that is an unpleasant answer. Sometimes it does help to have a computer with more cores to help with this. I have gotten up to 90% processor usage on a 12 core machine before.

hat differ in shapes, sizes and height the facade would be a mess. Some spaces need some light while other can't have any. I would like to have full freedom of creation inside the building, to make it as functional as possible. Thats why i decided the parametric "skin" solution would be best. Since the location has industrial past (factories made of brick) i decided that brick would give interesting result.
I tried creating the definition on my own but since i lack skill in GH i got some problems (especially multiplication of bricks and the diffrence between each "level" (half a brick on y axis) caused problems for me.
I post my simple sketch explaining the idea of definition i would like to create (sorry about quality):
1 - Brep - I would like to use 25x12x6cm (classic brick) but as well experiment with diffrent shapes - like the one on the right with hole inside - that would give more light. Thats why i think the best solution would be using brep for this definition.
2- Multiplication - biggest problem for me - I don't know how tall the wall would be, what will be the final shape of Brep (brick) and that's why i would like to manipulate this with sliders as well. All the walls are flat (maybe it would be easier to use surface?). As i managed to multiply the bricks easy way i don't know how to gain control over height of the wall - for example that it is 30 bricks high, but has each second row moved on x axis by the distance of 1/2 brick. I tried using Series but with no success. Could you help me with that please?
3 - Rotation - i would like to use image sampler for that so i can "paint" where i want more sun and where i dont need it at all (black and white). The rotation has to be limited to 180 degrees as well. Obviously i didn't get here yet, but i never used image sampler so if you could give me some advice how to use component and how to create such images i would be really grateful.
4 - More of a concept thing - since the connection angles differ from 90 degrees i will have to figure out how to connect the parts of the wall at sides ;).
I would like to ask you for help with the defintion, since i am totally stuck at step 2. I post what i came up with so far. Thank you for your time and help!
PS. I post an image that is pretty similar to one of options i would like to check for my building.

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…
till quite rough.
I went through your attached log but it seems to be a successful run, perhaps the error log wasn't attached. In any case, I believe we have identified this issue. The goal of the update fvSchemes component was to apply schemes to finalized meshes in an automatic way. While this is useful for new users it is also a dangerous thing to do in CFD studies.
The component works by relating mesh quality to the mesh non-orthogonality, which the checkMesh component reports. While non-orthogonality is one of the important criteria of mesh quality it does present difficulties on some kind of meshes, especially like the simple cases that BF has been meshing so far.
The example case of simple box buildings in a wind tunnel above for instance will appear as a good quality case for even the lowest of cell-count meshes, simply because it is an orthogonal geometry. That means that checkMesh will probably report low values (imagine an empty blockMesh of 10m blocks has a non-orthogonality of 0) which in turn means that higher order schemes might be paired with actually low quality meshes. This I believe is causing problems.
I posted a possible solution to this here https://github.com/mostaphaRoudsari/Butterfly/issues/57. The idea is that Buttefly provides additional options to the users, enabling them to choose between first-order (faster, more robust, but lower quality schemes) and second-order (slower, less robust, but more accurate) schemes depending on mesh quality, stage of assessment, etc. In cases like the above mesh quality a first-order scheme might provide a better option. To test this I am attaching an fvSchemes file you can use by replacing yours in the /system folder of the case.
As a note however, I would like to stress there is so much that a tool like Butterfly can provide in this area. Meshing is a quite complicated and demanding part of the process, involving a lot of trial and error. Sometimes the problem is just the mesh and not the solution options (GIGO stands true in CFD as well). It does however get easier with experience. The safe advice is the simplest one: when changing solution options doesn't help, refine mesh and run again.
Kind regards,

Hi friends,
trying to get a cumulative sky image metric to run and encountered an issue with the image-based metrics component. It throws:
Runtime error (KeyNotFoundException): honeybee_materialLib Traceback: line 768, in main, "<string>" line 1442, in script
I guess this is some sort of setup issue on my end, or I messed up the definition? Any help appreciated.
Thanks,
Max
