algorithmic modeling for Rhino

As of a few hours ago, I can no longer conduct radiation analyses through Ladybug. The problem seems similar to the previous post by GB, except I have not received an error message. Instead, everything looks normal except that no matter how I change the parameters or flip the surfaces, every surface is registering as 0 kWh/m2 (as seen below). I've tried multiple files (including files that worked fine yesterday) but I always get the same result.

I've attached all my files below. Any help would be greatly appreciated!

Hi Caleb,

Simple: You just need to insert LB_LB component and let it fly. That's it.


I wish it were that simple, but I've already done. I went back to verify and still got the same result.

This so strange then because on my end it works completely fine.

I will try to set the UseOldRes in the genCumulativeSkyMtx component to False, so it will recalculate the sky radiation.


That is strange.

I really have no idea why it stopped working for me. Maybe I need to re-install Ladybug.

I re-installed Ladybug, but unfortunately the radiation analysis still does not work.

Try another weather file.

Did you tried what i suggested above?

Got it to work! Both of those methods did the trick. I guess I just had to toggle UseOldRes to False a few times before it actually registered and recalculated the sky radiation.

Thanks a lot for the help Abraham.

No problem.

But now i'm having a question for Mostapha, which is kind of related:

The genCulativeSky calculation results are supposed to be located at c:\ladybug. I don't find it there. Do you know where they are now?

Hi Abraham,

As Chris mentioned on Github, if the user doesn't have full access to C:\ then the folder will be at C:\Users\%USERNAME%\AppData\Roaming\Ladybug\ to avoid any potential permission issues.

I tried reinstalling Ladybug and changing the EPW file and it's still all blue... Any suggestions?

Check the normal directions.


I tried flipping them, and exploding the brep into individual surfaces.  It's still showing up all blue.

I've attached the files.  Do you have any other suggestions?  Thanks for your help.
