Outdoor Airflow Butterfly Vectors going through the building

Hi all,

I’m using butterfly plug to create a wind analysis.

Would anyone know why the vectors are going through the buildings? instead of bouncing off it?


@mtieu The vector can be adjust by grasshopper , so vector is not suitable for analysis wind speed . You should use wind speed for data visualization.

Hi Ming,

I’m using the butterfly plug-in and the vectors was in the example file, I can’t upload anything but could you have a look at my script?

Thank you!
