 Hello

 I'm performing an adjoint sensitivity analysis in a transient problem and I
 need to save the entire solution history. I don't have many degrees of
 freedom or time steps so I should be able to avoid memory problems. I've
 thought of creating a std::vectorVec and save all the PETSc Vec that I
 get from TSGetSolution there. Would this be a problem if I'm running the
 simulation in parallel? Is there a better way to save the entire solution
 history in memory?

Your suggestion is fine.  I would do it from a monitor (TSMonitorSet)
and VecCopy the solution vector into your array of solutions.
