Dear Hamed, I think you can only use the TrilinosWrappers::SolverDirect classes for TrilinosWrappers::MPI::Vector 's and of course TrilinosWrappers::Vector 's.
Unfortunately, I've no experience with PETScWrappers::SparseDirectMUMPS <https://dealii.org/8.4.1/doxygen/deal.II/classPETScWrappers_1_1SparseDirectMUMPS.html>, and I don't think we have included that to candi so far. (You need to install mumps against your mpi compiler and point to that during the petsc installation) Best regards Uwe On Tuesday, October 25, 2016 at 3:17:39 AM UTC+2, Hamed Babaei wrote: > > Hi friends, > > I am parallelizing a code similar to step-44 in which it is possible to > use either an iterative solver SolverCG or a direct solver, > SparseDirectUMFPACK.
