Thanks for your detailed explanation. I tried your method and my code
works right now!

That would be my first guess.
I don't know much about MPI. Could someone explain th
Hi, guys,
I have a problem using MPI. The behaviour of my code becomes weird.
The following is part of my code where the problem is:
// First output mesh and nodal data
const MeshBase& mesh = es.get_mesh();
std::cout << '[' << libMesh::processor_id() << "] "
<< "writing e
Hi,
if I use
./configure --disable-mpi
I get the same problem
Running the samples directly doesn't work either. If you don't have time
- maybe someone else has any suggestion?

Robert,
I'm sorry I don't really have time to dig into this at the moment but there are
a few more things you can try. First if you just want to play around with
libMesh you don't need to run with the MPI library. You might try disabling
MPI when you run configure to see if that will provide

I used the libraries mpich2 and libpetsc3.0.0 from the Ubuntu

For me it is strange that it worked fine with the version which I

Robert, I have been running libMesh on Ubuntu every release since 8.04. We
have it running right now on 10.10 without any issues. The one thing that we
do slightly different than many users though is that we build our own MPICH2
library to link against instead of using the packages available t
Hi,
I have just tried to install the latest libmesh release in Ubuntu
karmic. I just downloaded the folder and used ./configure and make to
install libmesh.
However, when I want to do
make run_examples
I get the following error message:
Fatal error in MPI_Comm_dup: Invalid communicator, error
Hi all
I tried to execute the 4th example in parallel but it seams that it fails
to run!
I typed on the console: mpiexec -n 2 ./ex4-opt -d 2
but when it is run then (except for printing mesh.print_info() &
equation_systems.print_info() infos) then the following messages appear:
Fatal error in M
