Annual Wind Analysis issue

Grasshopper Eddy3D

Hello folks,

I am writing to ask about the following issue regarding the annual wind analysis template on Eddy (main version). I hope you would be able to provide some assistances.

I did not do anything with the template except updated the epw for my region, but as I ran your template on annual wind analysis, the Wind Factor function failed, yielding two issues: 1. Solution exception: Object reference not set to an instance of an object. 2. Data conversion failed from Number to Vector. Therefore I cannot generate the analysis. Did other users also encountered these issues? Would you know the possible fixes for them?

I however downloaded the EPW to local drive and plugged in directly. Rest is just out of box.

I had the same issue and then solved it. I had done few mistakes.

1 - when change the epw file with one stored locally you need to bypass the C# script and link it directly to ABL component EPW input

2 - do step 6.CLEAN first then run all the button in the right orders

3 - change the field input of the component Visualize Probes to the desired analysis

Hello, following the method you provided, I have successfully run the ‘annual wind analysis’ module and analyzed the wind velocity distribution of the site. However, I still have a question. In the ‘Visprobes’ block, the initial template provides ‘name’ and ‘field’ options as ‘aoa’ and ‘age of air’. If I want to continue analyzing ‘age of air’ or other fields, the aforementioned issue will still persist. I’d like to ask if you have any suggestions for solving this problem. Thank you for your help!
