there are 41 U-curves, each with 161 points along them, I want to pick a point and be able to search among only the 41 points of the same index value.
I've tried to do a series component going into a list item component, which works when only one index is selected from the 161 available; I thought the same logic would work to be able to run the same operation on all 161 indices at the same time, but it doesn't seem to work quite so simply.
Another way I thought of doing it would be to say I want to pick a point of branch x, index B, and search only the two points next to it, which would be x,B+1 and x,B-1, but I don't know how to perform this logic in grasshopper.
Any suggestions?…

- 100.
After that, I want to separate it into 5 different lists in spesific thickness.
in this case of 0-100 so it would be :
1. if the distance 0 - 20 then the thickness is 5
2. if the distance 21 - 40 then the thickness is 10
3. if the distance 41 - 60 then the thickness is 15
4. if the distance 61 - 80 then the thickness is 20
5. if the distance 81 - 100 then the thickness is 25
But, the problem is the list of distance isn't static between 0-100. It could be 5 - 250 / 3.5-175/etc.....
Could you help me how to make the expression?? Is this possible if I make one expression?
thank you.

nb: distance and thickness hasn't mathematical relation.…

onent are experiential or location specific. For example: humidex has been derived and widely used in Canada.Also both humidex and discomfort index should be used in in-shade conditions.For universal applications and locations, you should concentrate on either PET or UTCI (this is what "Outdoor Comfort Calculator" component is based on).
I have found out, that for instance - OutdoorComfortCalculator - which considers temperatures of 9-26 and other factors, gives the % of comfortable time outdoor for instance in Kenya in Africa (high temperatures and humidity) 55%, whereas within the same .epw data and some additional factors added to the Thermal Indices component, the "humidex" or "Discomfort index" give a result drastically lower, I think it was even 1-5% comfortable.How is that?
Yes, this is one of the issues that I have with UTCI index: the authors wanted to make it as an index applicable in any type of climate. To create the UTCI comfort categories a number of data has been collected from different locations (for hot humid climate, it was the data from Madagascar. I may be wrong on this). This resulted in universal comfortable range of 9 to 26 C which you mentioned. How would the people in Madagascar perceive the feel like temperature of 9 degrees as comfortable is beyond my understanding.Thermophysiology of a human in Madagascar, and in Poland is the same. However their acclimatization is quite different, which raises the issue with the upper universal comfortable range. In general people who live in hotter climates have a bit higher tolerance to high temperature than those living in continental climates. And vice-versa: their tolerance to lower temperatures is lower than the tolerance of the people from the continental climates. Here is a comparison of the UTCI - PET stress categories:
UTCI
all climates stress category
above +46 extreme heat stress+38 to +46 very strong heat stress+32 to +38 strong heat stress+26 to +32 moderate heat stress+9 to +26 no thermal stress+9 to 0 slight cold stress0 to -13 moderate cold stress-13 to -27 strong cold stress-27 to -40 very strong cold stressbelow -40 extreme cold stress

I attached below an example of PET humid climate comparison with UTCI, for in-shade and out-shade conditions.As it can be seen UTCI shows the percent of time comfortable: two times higher than PET.

t the sum of the three parts equals the length of the original list). This will generate a tree of lists. If you want these lists to actually have separate outputs, you can either [Explode] the tree, or you need to use other kinds of components.
For example you could use [Split List] twice, once to split the lists into parts A&B vs. C, and then another Split List component to split the still combined A&B into separate A and B lists.
Or perhaps use three individual [Sub List] components, all with different domains that represent your desired list lengths. So using your numbers, the first splitting domain would be from 0 to 21 (for a total of 22 points), your second splitting domain would go from 22 to 25 (giving you the next 4 items) and the third domain would go from 26 to 41 (giving you the last 16 values).…
