Hi Carlos, <br>
<br>
you're right, on the current master the nonoverlapping Jacobi
version does not compile. <br>
We need to fix that asap.<br>
However the nonoverlapping SSORk version does work even with 2
processors. <br>
I have tried out the example in dune-pdelab-howto:<br>
- src/convection-diffusion/nonoverlappingsinglephaseflow.cc<br>
<br>
Maybe adapt this code from the pdelab-howto.<br>
<br>
Best regards, <br>
<br>
Marian<br>

<br>
<br>
I have problems with the nonoverlapping linear solvers in the
attached test case.
<br>
My dune version latest version of all dune core modules and latest
pdelab version from
<br>
GIT repo.
<br>
<br>
Operating system is : Opensuse 13.2
<br>
g++ : 4.8.2
<br>
MPICH: 3.1.3
<br>
<br>
1) Dune::PDELab::ISTLBackend_NOVLP_BCGS_SSORk works well on sinlge
CPU.
<br>
Solver produces explodes if I use more than 1 cpu.
<br>
<br>
2) There are some compilation issues with Jacobi preconditioner.
<br>
(Please uncomment out line 243 in the attached file)
<br>
<br>
(this attached tets example is modified from testpoisson.cc in
pdelab/test directory)
<br>
<br>
Please let me know if you need more information.
<br>
Thank you for looking up the issue.
<br>
<br>
PS: this test example works well with older version (dune-2.3.1)
<br>
<br>
Best regards and thanks in advance,
<br>
Carlos.
