Why do I get 4402 error when I apply a static displacement to a 2 node system with a PBUSH element in the middle and one node clamped ?
Do I need another element ?
Is it necessary to create mass on the nodes ? is CBUSH element alone enough to create a system that has a certain stiffness and I can apply the imposed displacement to its nodes ?
I did it a quick trial.
1 cbush element between 2 nodes with stiffness in X and Y. Then BC:
- 1 end clamped
- the other end non zero constrain option under constrains: only x and y 1 mm. Rest 0
If you apply load with dispalcement option, then, I guess you do not have "free" dof to solve the system. You would need more nodes.
Hope it helps.
