Hi, I'm trying to solve a large deformation problem interactively using updated lagrangian formulation. I have some trouble in updating the mesh. In the code I attached here, I attempted to define new_ulf_iteration in problem.nls_iter_hook (line 149) and nls.iter_hook (line 152). But both methods failed to update the msh. How do you update mesh in interactive mode? Thanks!
