PETScWrappers::MPI::BlockVector with Direct Solver

[mau....@gmail.com]

Hello to everyone,

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 ?

Thanks!

No. You have to use non-blocked matrices and vectors if you want to use one of
the PETSc direct solvers.

Best
W.
