Dear prof. Bangerth, I am not sure how to answer your question. I'm using a very basic a setup equivalent to step-8. Therefore, I have a solution vector with final displacements where each entry corresponds to the displacement of a dof. My aim is to find the initial position of the vertices in the form of std::vector<Point<dim>> and the final position (i.e., the initial position + its displacement) in the same form.
Best, David.
