swing move
 

hello everyone, i m trying to swing a leaflet inside a flow.
First, i tried it by using "fixed support" on a are to run the movement by deformation, But now i just need to swing it with using more rigid material, as its pimmed by one edge like a window or door etc. but when the load is gone, it needs to get back its starting point. What should i use in Transient Structural ?

This is my area fixed supprted before is in the attachment.

Would be really appreciated if anyone helps...
