Hello Nik,

I am also having the same problem.
I scaled my model and this problem occurred.

I found a discussion here: Butterfly_Wind Tunnel Grading Issue - butterfly - Ladybug Tools | Forum
I couldn’t solve my problem. But, maybe it helps you.


Hello, Merin Abbas,

I was also advised to update Raino, but I have not tried it yet, maybe it helps you
