i have made a 3d model of diaphragm spring.
i need to simulate the way it works when force is applied at the center.
but i am unable to do so.
please help. i am only getting deflection in the center part where force is being applied. no deflection is occuring in the outer part of diaphragm.

i am afraid that my fixtures are wrong
