Outdoor Wind tunnel grading error

Hello I am having this error in grasshopper, I dont know why when I put values higher than 105 degrees the grading node throws this error: 1. Solution exception:Invalid input: 1.44
In this case I used 151 degrees as an input to create the vector for the wind tunnel node

Thanks in advance


Hello, How are you?

Kindly do you have any suggestions to solve this problem?

Butterfly gives that error mentioned above when the wind direction vector is changed in the wind direction component. It only accepts (0,1,0).

How could we import different angles without getting the error?

Many thanks in advance.
