I will like to simulate this part with Static analysis
The part have and banana that start with a diameter on 5mm an go down to 0,75mm i diameter.
it form a half circle with radius 5mm
But when i do i just fail, even at 1N, i have tryed from 1N to 100N....
If i'm using "small displacement" i will get somthing like on picture 3
Picture 1 is the force with 20N and Fixed geometry
Picture 2 say that deformation is to big to be realistic, but i got the part i my hands, and it will take more than 20N to bend it 2mm (with large displacement)
Picture 3 will show up after the solver fails and i restart the samen simulation with the same config.
What i'm doing wrong ?
