Daylight Gridbased Simulation Error (rtrace: fatal - truncated octree)

old forum

Hi all, I am a new user of Ladybug and Honeybee, still watching all the tutorials and I encountered a problem. I was trying to get this script with a simple box geometry working based on Mostapha’s tutorial on youtube (https://www.youtube.com/watch?v=BqbCkjMYxdk).
The example file worked fine after I updated it, but I tried to re-do the script by myself and run the gridbased simulation for illuminance and it gives me a fatal error message (as seen on the image, also for DF simulation):

Failed to read the results!
rtrace: fatal - (WWR_.5_TVis_.6_RAD.oct): truncated octree

Runtime error (PythonException): Failed to read the results!

Traceback:
line 336, in script

I checked everything again and it still gives me the same error. I uploaded 2 of my script files (one where both illuminance + DF simulation did not work and another one where DF simulation could work). I am using the latest LB+HB version and Copenhagen as my weather file.
Can someone tell me what is wrong and help me to solve this issue?

Thanks before

Stephanie,

Just disconnect the panel from the additionalRadFiles input in the HB_runDaylightAnalysis. Do that also for the DFanalysis. Unless you have files with radiance dfinitions that should be embedded in the simulation you don’t need to connect here anything.

BTW, why you are not connecting directly the mesh output of the genTestPts to the recipies inputs?

-A.

Thank you for your help, Abraham, it works well now. I think I misjudged the string on the example file connected to the additionalRadFiles.

And I realized that the newer version has the move component already in the genTestPts. Thanks for reminding me about this, I was too naive following the tutorial files with the older version. I will be aware now!

Thanks again!
