Saving and retrieving solution vectors for adjoint based optimization

[Praveen C]

Dear all
I am doing an adjoint based optimization for which I solve a forward problem and an adjoint. I need to save the forward solution at different time instants and read it back to compute a gradient. What methods are available to do this in deal.II ?
Thanks

The various vector classes have functions that can just dump the state of the
vector into a file (the 'block_write/read()' functions), or you can serialize
the whole vector via the serialization framework. (There is no tutorial
program for serialization, but you can find examples of how this works in the
tests/serialization/ directory).

Alternatively, there is also the SwappableVector class that could help in your
case.

Best
