Dear Chucui, The Triangulation <https://dealii.org/9.0.0/doxygen/deal.II/classTriangulation.html#a5ae613e76606c08f919aa6e4bdf5f94a>, DoFHandler <https://dealii.org/9.0.0/doxygen/deal.II/classDoFHandler.html#aee69e8dd102b00e6e2e706ab43ea6c2a> and Vector <https://dealii.org/9.0.0/doxygen/deal.II/classVector.html#a753f299ab91013f742448f5bfc0f4b68> classes support serialization, that is to say that they have built-in save() / load() functions. The GridIn::read_vtk() <https://dealii.org/9.0.0/doxygen/deal.II/classGridIn.html#a058cd187cea704428ac1118410cd0fb8> function can supposedly construct a triangulation from a solution vector, but I’m not sure if this is working at the moment (see this GitHub issue <https://github.com/dealii/dealii/issues/7296>). I don’t think that there exists a mechanism to read in the numerical data from VTK file as of yet. So I would suggest that you utilise the serialization capabilities, which should allow a complete restart of a simulation from any tilmestep. I understand that this is what the ASPECT library <https://aspect.geodynamics.org/> does.
Although it does not directly help you restart a simulation using VTK data, I hope that you find this information useful.
