Hi, That’s quite an interesting coupled problem that you’re solving!
If I understand correctly, you’re wanting your one problem to solve to completion, and you then want to save that state and load it in another, new simulation? If that’s the case then we have save/load functionality built into most (if not all) linear algebra vectors (see here in the documentation of the Vector class <https://dealii.org/developer/doxygen/deal.II/classVector.html#a9c9b9333d11630bf0fc82a7957e0d1c1>, for example). Of course, you’ll need to access that data with a matching DoFHandler (paired with the correct FE / FESystem), but all of those are also serialisable too. Although I don’t think that we have too many tutorials that demonstrate serialisation (I cannot think of one off the top of my head), we do have a collection of tests <https://github.com/dealii/dealii/tree/master/tests/serialization> that can illustrate how its done. Was that the information that you were looking for? Best, Jean-Paul > On 30.
