As I said before, I have checked out master branch and merged with your
stefano_zampini/pcbddc-primalfixe branch. configured, compiled successfully.
I have used --with-pcbddc option in configure as Barry suggested.
However, tests are failed with following reason:

I think the problem is somehow related to
-pc_fieldsplit_schur_precondition selfp. In the example below your are not
using that option.
Here is the selfp output. It retains the A00 solver.

Thanks! I've spotted another difference: you are setting the
fieldsplit_0_ksp_type and I'm not, just relying on the default
instead. If I add -fieldsplit_0_ksp_type gmres then is also get
the correct answer. Probably, you will get my problem if you
remove -fieldsplit_velocity.

Hello,
This may be rather a C/C++ question, but ...
I encapsulate some petsc functions into c++ classes. Since I don't want
to pull all petsc symbols into the global namespace for anyone using my
classes I try to put petsc into it's own namespace:
Header petsc.h:

Dear PETSC users,
I tried to use SCOTCH 5.1.12b in my PETSC codes since MUMPS has
compatibility issues with the latest SCOTCH library.
I was told that SCOTCH/6.0.0 that comes with PETSC/3.5.0 is automatically
downloaded and installed. Is it still possible to use old SCOTCH library

Hi Barry,
Thanks for the suggestion. I downloaded the scotch tar ball in the petsc
source directory, and set up the configure flag as suggested, but I got the
following error:

In general I am also having to try by trial and error which solvers and

Is there a list somewhere?

Did you read my comment on your scicomp post?
I recommend using src/ksp/ksp/examples/tutorials/ex45.c since it was
written by us (Barry) and is more controllable via run-time
perhaps unrelated - but are you sure you had the latest master?

Hi all,
So I understand how the FEM code works in the DMPlex examples (ex12 and 62).
Pardon me if this is a silly question.
1) If I wanted to solve either the poisson or stokes using the discontinuous
Galerkin method, is there a way to do this with the built-in DMPlex/FEM
functions? Basically
