Henry Schau

A spring element e.g. SPRING2 connects two nodes with a spring. Specify the displacement for the free node (the other node is a node of the model).

*BOUNDARY, TYPE=DISPLACEMENT

SPRINGNODE, 1, 1, 10.0

Moeen Khurram

@Henry thank you for your reply, you mean i have to attach one more spring to the existing spring and introduce displacement?

I will be really appreciated if you elaborate me lil bit more from the gui.

Victor J. Аdlucky

It seems that spring must have a bi-linear characteristic with high stiffness at the beginning. This high stiffness and the point (relative displacement, force) where curve changes its tangent have to be found experimentally using condition that the stretch is small when desired linear spring displacement is reached.
