Sunpath Solution Exception:Math Domain Error

[Evan]

Hey guys,

I’ve just downloaded ladybug plug-in to do some sunpath analysis , when i connected epw location to ladybug_sunpath _location , it show up error report : Sunpath Solution Exception:Math Domain Error.

the report shows:

        {0;0}

0. Current document units is in Millimeters
1. Conversion to Meters will be applied = 0.001
2. Runtime error (ValueErrorException): math domain error

Traceback:
line 1565, in solInitOutput, “”
line 1598, in drawDailyPath, “”
line 1625, in drawSunPath, “”
line 437, in main, “”
line 713, in script

Any idea why this might be happening ?

Hi @Evan . Please update your ladybug tool using ladybug update component. Slide on to canvas and toggling that to true. Restart and it should work fine.

Thanks for the correct answer @Asisnath and I just wanted to link to the official answer posted here:

"Sunpath" component does not read some of EPW files

Hello All, Sorry for the very late response here. There was actually a fix that I just pushed to the sun position calculation last week that I believe should fix the issues reported here: The fix isn’t in the Food4Rhino stable release but you can get the updated Ladybug_Ladybug component that contains the fix by running the “Ladybug_Update Ladybug” component.

It’s odd that everyone suddenly got this error after years of it never surfacing. I have to imagine that there was some update to IronPython with the latest Rhino or something like that, which suddenly made this an error whereas it previously was auto-corrected. In any case, it’s all fixed now.
