Try to redo the problem, but with the full stent model instead of the 1/8th model. Do you still get similar results? How does the model setup change?
- Hint - How does the symmetry help us to simplify constraining the model? The symmetry in the partial model helped us to use boundary conditions in order to limit the rigid body motion (unconstrained motion of the model. Is there an easy way to restrict rigid body motion using a full model, and does this method affect the solution? Try constraining faces first, then try constraining points, and see if the solutions vary.
