Fail to read Radiance result for visualisation

Hi everyone,

I am dealing with an issue using honeybee and Radiance. I have successfully run daylight simulation (grid based analysis) but found error when reading the radiance result (using ‘ReadRadResult’). There are 6 figures attached that you can see.

Looks like this is related to ‘AnalysisRecipe’ where I input skyfile based on epw file (GridBasedSimulation). This generates 3 file outputs for analysis recipe and it leads the simulation to produce the number of data exceeding the number of grid cells (three times of gridcells). I found no error when applying DFSimulation for the analysis recipe because it generates only one skypath output (see figure 2)

Actually, I have solved this issue by using item selector to chose one of three outputs produced by ‘genClimateBasedSky’. It works! (see figure 3) But, when I changed to another output of skypath, the results changed by about 20-200 lux (I just noticed some values in panel). This led me to throw this issue in the forum: which skypath is trustable that I can choose? and or whether myworkflow in grasshopper is not correct? (looks like it’s better to use honeybeeplus but I haven’t explored it yet)
Also, the illuminance value produced in my model is too big (see figure 5). Please give me some explanation about this…


Here is I attached my gh file

Latihan 2 radiance daylight factor (847.7 KB)

@sunarywend Your grasshooper file maybe have some bug. It opened epw file 5-6 times and ran radiance 2 times.And it gave me some warning as below.
After ran your grasshooper file,I found a easy bug.It is about the north sign. You set 3 item to climate-base sky, so it generated 3 sky. And ran 3 times for 3 result files.You just need to set 61 to north directly, then your model will be run normally.

Thanks for your solution. It works!

My grasshopper opens epw file several times because I put three ‘input weatherfile’ objects there. Some of them are applied for EnergyPlus simulation input. In the file you see, I try to integrate input simulation for EnergyPlus and Radiance in one file.

Related to the material, my grasshoper didn’t give me those warnings as you attached.
