Dear Timo,
Sorry, I did not mean to write to your personal e-mail. Just pressed the
wrong reply button by mistake.
Thank you very much for your reply. I will check the way how I set
mpi_communicator now. Hopefully, will find the problem.
I have changed step-40 couple of days ago myself to
and from your email I got off-list (please try to use the mailinglist):

Dear Timo,
The main reason I do this is that I do not understand how to reuse this
decomposition in deal.ii.
I am relatively new to deal.ii and C++, and I have never used MUMPS before.
The way I set it up with SparseDirectUMFPACK was to use InnerPreconditioner
structure:
template
struct
Dear Timo,
Because I do not understand how to reuse this decomposition in deal.ii.
I am relatively new to deal.ii and C++, and I have never used mumps before.
I would appreciate any advice on this. Maybe there is some example in deal.ii
that use mumps to construct a preconditioner.
Thank you

Dear Timo,
Thank you for your reply.
I am still having trouble with implementing my code with MUMPS.
I will briefly describe the problem:
I am solving 2 systems of Maxwell's equations in the following way:
the systems are Ax1=b1 and Ax2=b2;
A is a sparse block symmetric matrix (C -M; -M

You have to
Dear All,
I have modified step-22 to solve system of Maxwell's equations, and then
used step-40(and 55) to parallelize the code.
In the serial version I used
template
struct InnerPreconditioner;
template<>
struct InnerPreconditioner<0>
{
typedef SparseDirectUMFPACK type;
};
template<>
struct
