Model wind driven rotation of a geometry

[wonggeric]

I’m currently trying to determine how a sculpture will rotate under different wind conditions. One issue I can’t figure a solution to is to update the points where the wind load act on (only the parts of the sculpture that is exposed to the wind). Here’s a picture of the sculpture that I’d like to rotate around the z-axis.

Has anyone created models similar to this? Tried using Kangaroo and creating my own script. Thanks in advance for any help/suggestions people have!

That’s a physics problem. There is no general, simple relationship between geometry quantities such as centroids and the equivalent location where aerodynamic forces and moments act. For certain types of bodies such as wings with the wind acting from certain directions there are simple relationships, but nothing general for all geometries.
