I have read the documentation but I didn't find anything related to using
BlockVector from PETScWrappers with a Direct Solver, for instance
SolverPreOnly should work as a Direct Solver with PETScWrappers::PreconditionLU.
In my serial code I used SparseDirectUMFPACK, but it is incompatible with a
PETScWrappers::MPI::BlockVector.
Is there any way to use a Direct Solver with PETScWrappers::MPI::BlockVector ?
No. You have to use non-blocked matrices and vectors if you want to use one of
the PETSc direct solvers.
