Hi,
I got the below error when calling KINSOL::solve() with Trilinos MPI vectors.
It looks KINSOL tried to call scale() for a ghosted vector.
The vector has ghost elemets probably because I passed
a ghost vector as "initial_guess_and_solution" argument to solve().
I can pass a non-ghosted vector as "initial_guess_and_solution", but this will
cause another problem in the residual assembly function which requires ghosted
elements.
Any advice on this issue would be appreciated.

An error occurred in line <2146> of file
</usr/src/dealii-v9.5.0/include/deal.II/lac/trilinos_vector.h> in function
void dealii::TrilinosWrappers::MPI::Vector::scale(const
dealii::TrilinosWrappers::MPI::Vector&)
The violated condition was:
!has_ghost_elements()
Additional information:
You are trying an operation on a vector that is only allowed if the
vector has no ghost elements, but the vector you are operating on does
have ghost elements. Specifically, vectors with ghost elements are
read-only and cannot appear in operations that write into these
vectors.
See the glossary entry on 'Ghosted vectors' for more information.
