Wind - Physics

Hi dear forum,

there is a little problem i have, i think your knowledge could be very helpful.
I created a simple curtain (+ pole) and placed a wind behind it.
The result looks very good, but is not working 100%.

I think its because of the wind or physics/collision settings.
If i turn/twist/move/rotate… the object (simulation mode),all things look the way they have to.
Except the wind. Although it’s placed right next to it, the cloth is not moving.

I saw some additional tutorials, but i didn’t find the correct answer.
Do you have any ideas ?

You can see the current physics/collision - settings and a rotated curtain as pic here.

Thanks for your time and effort!
Stay healthy.
