he direct sunlight hours per node per day. With the actual component it is not possible (I think). You can calculate only totals (per node=sunlightHoursResult output and all the nodes=totalSunlightHours output). What is interesting the existing output sunIsVisible but the thing is that it considers the hours of sun from the sunrise to the sunset so when you try to split the list using the 24h it doesn't work (fig 1). So if you don't know for every day of the analysis period the duration of the day you cannot split the list coming from the output sunIsVisible (Fig 1). To overpass this I had to calculate the actual hours of the day for every day of the analysis period from the sunPositionInfo of the SunPath component (Fig 2) but it is very tricky. So what I suggest is to add a second sunIsVisible outup but on the 24 hours. Thank you!!

is not accurate enough, so I'm using Grasshopper instead.
Currently I'm interpolating the curve by hand. Adding control points to the curve and then moving them along the curve to get an error of <0.2mm at the leading edge and an error of <2mm for the rest of the airfoil. In total I use +-24 CP, but most of those are located at the leading edge, so in practice it is very useable. It's not that long a process but it will become very tedious very quickly when you have to do it quite a few times.
So I was wondering the following:
Is there a way to program Grasshoper (maybe with Galapagos) so that it does the following: - Automatically interpolate the imported airfoil (the one with 100+ CP) - So that it meets a set tolerance - While using as few CP as possible. - Bonus: Maybe there is a way to set the tolerance for different regions of the curve, so that it can interpolate precisely for the leading edge and less precise in other regions Would be great if anyone had an idea or a view pointers so I can work this out.
UPDATE: Was wondering if I could maybe write a PythonScript to do the job.
All it really needs to do is start out with InterpCrv.gh, check the MaxDev inbetween two control points, add one if MaxDev > Tolerance or move to the next two point if MaxDev < Tol.…

ll these 12500 points.
Group 1 would represent the point located at 0, 5, 10, 15, 20 etc.
Group 2 - 1, 6, 11, 16, 21 etc.
Group 3 - 2, 7, 12, 17, 22 etc.
Group 4 - 3, 8, 13, 18, 23 etc.
Group 5 - 4, 9, 14, 19, 24 etc.
I can create the pattern but the selection of points are all the points in row 0 and then all the points in row 5 and so on.
I would like the selection of points to start at the bottom left, and sequentially continue to the right and then continue on the 2nd row (left to right & bottom to top). i am hoping the pattern i am trying to achieve is more understood with the quick screen capture I uploaded.
the end goal is to be able to select all the points in the grid that are in each pattern.
Thanks in advance for any guidance with this. …

adiation values I get this for the same 24 hour analysis period:
As Chris pointed out, it seems to be missing half of the day. I double checked the direct radiation output numbers and your component is doing what it is supposed to from what I see.
Here is another view of the sky from the edited epw file:
Again, I expected a sky that more resembled the one produced by the original .epw file - just different values.
Maybe the raw data I supplied is not correctly formated - or the time step is off. The direct radiation replacement data was given by hour starting from the hour after midnight.
Any idea, Sarith?…
helped me solve some geometry problems).
I uninstalled energyPlus and installed again, updated the components, and hanges replaced the once that were not automatically replaced.And I have a deadline :(
Could it be because there are no materials assigned?
Thanks a lot.
