Dear all,
I am getting a running error that I can not really understand when calling
*PETScWrappers::PreconditionILU
preconditioner(system_matrix)*. However, it seems to work with
*PETScWrappers::PreconditionBlockJacobi preconditioner(system_matrix).*
May I ask for help to understand/solve this issue? The solver function ad
error that I get is the following:
*void LaplaceProblem<dim>::solve()*
* {*
* PETScWrappers::MPI::Vector
completely_distributed_solution(locally_owned_dofs,mpi_communicator);*
* SolverControl cn(completely_distributed_solution.size(), 1e-8 *
system_rhs.l2_norm());*
* PETScWrappers::SolverGMRES solver(cn, mpi_communicator);*
* PETScWrappers::PreconditionILU preconditioner(system_matrix);*
* solver.solve(system_matrix, completely_distributed_solution,
system_rhs, preconditioner); *
* constraints.distribute(completely_distributed_solution);*
* locally_relevant_solution = completely_distributed_solution;*
* }*

The violated condition was:
ierr == 0
Additional information:
deal.II encountered an error while calling a PETSc function.
The description of the error provided by PETSc is "See
https://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html for
possible LU and Cholesky solvers".
The numerical value of the original error code is 92.
Thank you very much
