Problem generating a radiation rose with hydra example

Hi Guys!

I am using the example RADIATION ROSE provide by Mostapha Roudsari to make a radiation rose for Stuttgar with an epw file downloaded from energy plus web but it does not work.

The problem say that input radiation are all 0. What is the problem? I have attached the file.

Thanks!

Eduardo,
I have not checked your file yet but my initial guess is that you are selecting a sky at nighttime. I will try to look soon.

Eduardo,

Your file is running fine for me.

Can you post the exact error and a screenshot of it?

The warming is: RADIATION VALUES ARE ALL 0.

It just occurred to me that this issue is probably related to this one:

Can you check the epw file that you are using and make sure that it's size is much larger than 1 kB. Alternatively, can you upload the epw file that you are using?

Eduardo,

It seems my intuition was wrong and I still have not been able to recreate your issue (both your GH file and EPW file are producing a radiation rose for me). I could not see Ladybug_Ladybug in your screenshot. Is it orange or red? If so, try setting a default folder as input to the component. The username of your computer might have a space in it, which prevents Ladybug from finding a good default folder as per these discussions:

Eduardo,

I am fresh out of ideas about what the problem could be. It is difficult to figure out the issue without being able to re-create it. I will see if I can get Mostapha to take a look at this or ask if he has any ideas.

If anyone else on this forum has experienced this issue or has thoughts about what it could be, please post.

Eduardo,

I can't reproduce the case either, but can you set the useOldRes_ in the HB_genCumulativeSkyMtx to False? This way it will re-calculate the sky radiation from fresh.
