I’m running a daylighting simulation in Grasshopper.
I created a grid on the workplane and used the HB Annual Daylight component. Besides DA and UDI results, I’d like to export annual illuminance data (raw data) for each grid point in both .ill and .csv formats.
According to the results panel, the raw .ill file should be generated in the specified folder. I checked the folder and found that a 0.ill file was created under project folder/initial_results. However, when I opened it with Notepad, the text was unreadable (garbled characters).
I’ve attached an image for reference. Could anyone explain how to properly generate or read the raw annual illuminance data from the .ill file? Is there a recommended way to convert it to a readable format like .csv?
The newer versions of the recipe is using binary Radiance files and NumPy files, which will reduce the disk space for each simulation.
You can convert the annual daylight results with the example file that I have attached. This will give you a new results folder with human read-able text files.
Thank you for your return, Mikkel.
I’m using Rhino 7 and GH 1.7.0.
I tried running the simulation by connecting the GhPython Script component as you suggested, but the problem still hasn’t been solved.
Judging from the error message(No script to execute), it seems that it can’t read the original .ill file.
I checked the simulation log, and the simulation itself was completed successfully, and the generated .ill file does exist:
C:/Users/SSEL/simulation/unnamed/annual_daylight/initial_results/final/0.ill
The example file you sent me is for version 1.9.0. Could this issue be related to the GH version I’m using?
Thanks for taking the time to read this.
I re-ran the simulation by entering my model information into the example file you provided, and it worked successfully.
It doesn’t seem to be a version issue.
I haven’t figured out what exactly caused the problem, but at least it’s solved for now.
Thank you!
