Keisei,

I'll suggest two options (recently one of my students "suffered" the same thing):

Option 1: GO to the directory where the sky matrix is calculated (usually c:\ladybug, but check this in the output of the LB_LB component). Look for the directory with the weather station name (or so). You'll see that the file is 0 size (probably). Delete it and try activating the simulation again.

Option 2: If 1 doesn't work, define another target directory in the input of the LB_LB component.

Hope this will work for you.

Thank you Abraham!!

but i'm still confused about check the output of the LB.

is seen in my picture? and how to delete the zero size?

and option2 seems to change a weather file location? such as from desktop to the other place?

sorr... i'm not familiar with grasshopper.

thank u very much!!!

Hi Keisei,

Can you try the attached file and let me know if it works. It basically does what Abraham mentioned.

Also can you share the weather file? Taipai_02_[Nowhere] doesn't look promising! It might be because the values are missing from the weather file.

WEA file is the Ecotect weather file format (also used for Daysim). This probably making you trouble. Try to use an EPW file.

Usually the EPW files size is about 1.5Mb. The file you attached is just 138 k.

Keisei, You should provide more information for us to be able to help. You can download an epw file from different sources: http://www.grasshopper3d.com/group/ladybug/forum/topics/faq-where-t...
